# Putting it all together and getting organized
> ### Instructor notes

> The goal of this last part is to put together all the pieces started in the
>previous lesson to build a manuscript that is fully automated. Most of the
>files are already provided but they are missing the key pieces that make
>everything work. In this lesson, participants need to copy and paste the chunks
>of code listed in the appropriate files. At the end, their directory should
>look like the content of https://github.com/fmichonneau/teaching-automation

```
## Tests
`testthat` has a convenient function called `test_dir` that will run tests
included in files in a given directory. We can use it to run all the tests in
our `tests/` folder.
```r
test_dir("tests/")
```
```
## Error in test_dir("tests/"): could not find function "test_dir"
```
Let's turn it into a function, so we'll be able to add some additional
functionalities to it a little later. We are also going to save it at the root
of our working directory in the file called `make.R`:
```r
## add this to make.R
make_tests <- function() {
test_dir("tests/")
}
```
## Figures
This is the code to generate the two figures in the manuscript:
```r
## add this to R/figure.R
plot_summary_lifeExp_by_continent <- function(mean_lifeExp) {
ggplot(mean_lifeExp, aes(x = year, y = mean_lifeExp, colour = continent)) +
geom_line() + facet_wrap(~ continent) + theme(legend.position = "top")
}
plot_change_trend <- function(mean_lifeExp, year_break) {
tmp_data <- get_coef_before_after(mean_lifeExp, year_break)
ggplot(tmp_data, aes(x = period, y = trend, colour = continent, group = continent)) +
geom_point() + geom_path()
}
## -----
```
This is the code to generate PDF files from figures, and the two figures as PDF files:
```r
## add this to make.R
make_figures <- function(path = "fig", ...) {
make_summary_by_continent(path = path, ...)
make_change_trend(path = path, ...)
}
make_summary_by_continent <- function(path = "fig", ...) {
mean_lifeExp <- get_mean_lifeExp(gather_gdp_data())
p <- plot_summary_lifeExp_by_continent(mean_lifeExp)
make_pdf(print(p), file = file.path(path, "summary_by_continent.pdf"), ...)
}
make_change_trend <- function(path = "fig", year = 1980, ...) {
mean_lifeExp <- get_mean_lifeExp(gather_gdp_data())
p <- plot_change_trend(mean_lifeExp, year = year)
make_pdf(print(p), file = file.path(path, "change_trend.pdf"), ...)
}
## -----
```
## Data
This is the code that generates the intermediate datasets:
```r
## add this to R/data.R
gather_gdp_data <- function(path = "data-raw") {
split_gdp_files <- list.files(path = path, pattern = "gdp-percapita\\.csv$", full.names = TRUE)
split_gdp_list <- lapply(split_gdp_files, read.csv)
gdp <- do.call("rbind", split_gdp_list)
gdp
}
get_mean_lifeExp <- function(gdp) {
mean_lifeExp_by_cont <- gdp %>% group_by(continent, year) %>%
summarize(mean_lifeExp = mean(lifeExp)) %>% as.data.frame
mean_lifeExp_by_cont
}
get_latest_lifeExp <- function(gdp) {
latest_lifeExp <- gdp %>% filter(year == max(gdp$year)) %>%
group_by(continent) %>%
summarize(latest_lifeExp = mean(lifeExp)) %>%
as.data.frame
latest_lifeExp
}
get_coef_before_after <- function(mean_lifeExp, year_break) {
coef_before_after <- lapply(unique(mean_lifeExp$continent), function(cont) {
mdl_before <- lm(mean_lifeExp ~ year,
data = mean_lifeExp,
subset = (continent == cont & year <= year_break))
mdl_after <- lm(mean_lifeExp ~ year,
data = mean_lifeExp,
subset = (continent == cont & year > year_break))
rbind(c(as.character(cont), "before", coef(mdl_before)[2]),
c(as.character(cont), "after", coef(mdl_after)[2]))
}) %>%
do.call("rbind", .) %>% as.data.frame %>%
setNames(c("continent", "period", "trend"))
coef_before_after$trend <- as.numeric(levels(coef_before_after$trend)[coef_before_after$trend])
coef_before_after$period <- factor(coef_before_after$period, levels = c("before", "after"))
coef_before_after
}
## -----
```
This is the code to generate the CSV files that contain the intermediate
datasets that are needed to draw the figures. The function `make_data` generates
both datasets at once.
```r
## add this to make.R
make_data <- function(path = "data-output", verbose = TRUE) {
make_gdp_data(path)
make_mean_lifeExp_data()
}
make_gdp_data <- function(path = "data-output") {
gdp <- gather_gdp_data()
make_csv(gdp, file = file.path(path, "gdp.csv"))
}
make_mean_lifeExp_data <- function(path = "data-output") {
gdp <- gather_gdp_data()
make_csv(get_mean_lifeExp(gdp), file = file.path(path, "mean_lifeExp.csv"))
}
## -----
```
## Cleaning
The only way to ensure that your analysis is reproducible is to delete all the
intermediate and final products to make sure your functions can recreate
everything from the raw data and your code.
Having the figures and the intermediate data files isolated in their own folders
in your working directory will allow you to make sure you only delete these
generated figures, and none of the original data.
```r
## add this to make.R
clean_data <- function(path = "data-output") {
to_rm <- list.files(path = path, pattern = "csv$", full.names = TRUE)
res <- file.remove(to_rm)
invisible(res)
}
clean_figures <- function(path = "fig") {
to_rm <- list.files(path = path, pattern = "pdf$", full.names = TRUE)
res <- file.remove(to_rm)
invisible(res)
}
## -----
```
## Make everything
These are wrapper functions to generate/delete everything:
```r
## add this to make.R
make_ms <- function() {
rmarkdown::render("manuscript.Rmd", "html_document")
invisible(file.exists("manuscript.html"))
}
clean_ms <- function() {
res <- file.remove("manuscript.html")
invisible(res)
}
make_all <- function() {
make_data()
make_figures()
make_tests()
make_ms()
}
clean_all <- function() {
clean_data()
clean_figures()
clean_ms()
}
## -----
```
and before we continue, we are going to replace the make_tests function with
something a little more comprehensive:
```r
## add this to make.R
make_tests <- function() {
if (require(testthat)) {
p <- test_dir("tests/")
if (!interactive() && any(p$failed)) {
q("no", status = 1, FALSE)
}
} else {
message("skipped the tests, testthat not available.")
return(NULL)
}
}
## -----

// OpenGL is literaly hitler to initialise a windowless context for, so no game.
// Leave it for someone smarter than me :G
//
// Here is guidance I received from my Graphics Lord, Elim Garak, on Discord:
// [5:44 PM] 🕴: Elim, my lord, plz tell me the simplest way of setting up a dummy OGL ctx so I can glGetString()
// [5:46 PM] Elim | iscicadabannedyet.com: You know how to acquire your function pointers, rite? For WGL, EGL, XGL shit etc(edited)
// [5:46 PM] Borgleader: glLoadGen >>>>> acquiring pointers manually
// [5:46 PM] Elim | iscicadabannedyet.com: or that
// [5:46 PM] 🕴: not really, no
// [5:46 PM] Elim | iscicadabannedyet.com: You just want to know how to get the dummy?
// [5:46 PM] Elim | iscicadabannedyet.com: oh
// [5:47 PM] 🕴: from what I've read it's impl-def land
// [5:47 PM] 🕴: OGL land is so fucking alien to me
// [5:48 PM] 🕴: from what I read I assume you use like WGL or some shit to make a ctx which allows you to call OGL-proper functions
// [5:48 PM] Elim | iscicadabannedyet.com: Basically, on Windows it's as trivial as wglCreateContext(GetDC(your_window_handle)
// [5:48 PM] Elim | iscicadabannedyet.com: WGL is the glue between the Windows window system and OGL
// [5:49 PM] 🕴: Can I use a dummy window for that?
// [5:49 PM] Elim | iscicadabannedyet.com: yes
// [5:49 PM] 🕴: cool
// [5:49 PM] 🕴: And what on non-Windows?
// [5:50 PM] Elim | iscicadabannedyet.com: On OS X, one doesn't need to jump through such hoops because the Apple lords integrated OpenGL 4.1 and below inside
// of their system SDK
// [5:50 PM] Elim | iscicadabannedyet.com: As for lunix, it's EGL over there
// [5:50 PM] Elim | iscicadabannedyet.com: https://www.khronos.org/registry/egl/sdk/docs/man/html/eglCreateContext.xhtml
// [5:50 PM] 🕴: So I don't need to set up anything on OSX, it will work OOTB?(edited)
// [5:50 PM] Borgleader: except their drivers are shit so theres no point inusing it 😛
// [5:51 PM] Elim | iscicadabannedyet.com: It will work in the sense that you can get any core profile out of the box, yeah
// [5:51 PM] Elim | iscicadabannedyet.com: will it work practically as borgleader mentions
// [5:51 PM] Elim | iscicadabannedyet.com: hehehe, fun times ahead 😛(edited)
// [5:51 PM] 🕴: right, so a raw call on OSX, WGL wglCreateContext() w/dummy window on Windooze and EGL on Linux
// [5:52 PM] Elim | iscicadabannedyet.com: yeah, on lunix eglCreateContext attaches to the display
// [5:52 PM] 🕴: Elim is the greatest man of all time
// [5:52 PM] Elim | iscicadabannedyet.com: bby, write code and be quiet 😛
// [5:53 PM] Elim | iscicadabannedyet.com: but yeah, it's p retarded

<h1 id="Loader简介"><a href="#Loader简介" class="headerlink" title="Loader简介"></a>Loader简介</h1><p><strong>Loader</strong>：是一个执行异步数据加载的抽象类。它是AsyncTaskLoader的父类，CursorLoader的祖父类。</p>
<p><strong>AsyncTaskLoader</strong>：它是继承于Loader的抽象类。在AsyncTaskLoader中有AsyncTask用来执行异步工作。</p>
<p><strong>CursorLoader</strong>：它是AsyncTaskLoader的子类。它可以查询ContentResolver然后返回一个Cursor，同时CursorLoader内包含ContentObserver对象来监听Cursor数据的变化。</p>
<p><strong>LoaderManager</strong>：它是一个抽像类，作用是用来管理Loader。LoaderManager关联到一个Activity或Fragment；例如，在Activity中通过getLoaderManager()可以获取到一个LoaderManager对象。</p>
<p><strong>LoaderManager.LoaderCallbacks</strong>：它提供了与”Activity或Fragment”交互的接口。LoaderCallbacks中共包行三个接口：</p>
<blockquote>
<ol>
<li>onCreateLoader()：根据所给出的ID，初始化并返回一个新的加载器。</li>
</ol>
</blockquote>
<blockquote>
<ol start="2">
<li>onLoadFinished()：当一个先前被创建的加载器完成了它的加载过程时被调用。</li>
</ol>
</blockquote>
<blockquote>
<ol start="3">
<li>onLoaderReset()：当一个先前被创建的加载器被重置时被调用，然后使加载器的数据无效。</li>
</ol>
</blockquote>
<p>总结：Loader, AsyncTaskLoader和CursorLoader都是用来提供异步加载的类；而LoaderManager则提供了管理这些异步加载类的接口。此外，Activity或Fragment保护了获取LoaderManager的接口，通过这样的接口，就可以在Activity或Fragment中实现异步加载任务！</p>

<h1 id="Loader使用示例"><a href="#Loader使用示例" class="headerlink" title="Loader使用示例"></a>Loader使用示例</h1><p>下面通过一则示例演示Fragment中执行异步加载的完整流程！该示例中，会在FragmentActivity中采用异步加载的方式查找并显示数据库中所有的图片的相关信息。</p>
<p>点击查看：<a href="https://github.com/wangkuiwu/android_applets/tree/master/api_guide/app_components/loader/loader_picture/LoaderTest" target="_blank" rel="noopener">Loader示例的完整源码</a></p>
<h2 id="1-获取LoaderManager，并执行initLoader"><a href="#1-获取LoaderManager，并执行initLoader" class="headerlink" title="1. 获取LoaderManager，并执行initLoader()"></a>1. 获取LoaderManager，并执行initLoader()</h2><pre><code>public class LoaderTest extends FragmentActivity
implements LoaderCallbacks<Cursor>, OnItemClickListener {
...
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ListView)findViewById(android.R.id.list);
simpleCursorAdapter = new SimpleCursorAdapter(
this,
R.layout.list_item,
null,
STORE_IMAGES,
new int[] { R.id.item_title, R.id.item_value}
);
simpleCursorAdapter.setViewBinder(new ImageLocationBinder());
listView.setAdapter(simpleCursorAdapter);
// 注意此处是getSupportLoaderManager()，而不是getLoaderManager()方法。
getSupportLoaderManager().initLoader(0, null, this);
listView.setOnItemClickListener(this);
}
}</code></pre><p>说明：需要重点关注的是getSupportLoaderManager()，它的作用是获取LoaderManager。然后，通过initLoader()初始化Loader。</p>
<p>initLoader()的完整声明如下：</p>
<pre><code>public <D> Loader<D> initLoader(int id, Bundle args, LoaderManager.LoaderCallbacks<D> callback);</code></pre><p>说明：<br>(01) id是Loader的唯一标识。<br>(02) args是Bundle，这里赋值位null。<br>(03) callback是回调函数。后面会给出回调的实现。 </p>
<h2 id="2-实现LoaderManager-LoaderCallbacks接口"><a href="#2-实现LoaderManager-LoaderCallbacks接口" class="headerlink" title="2. 实现LoaderManager.LoaderCallbacks接口"></a>2. 实现LoaderManager.LoaderCallbacks接口</h2><p>LoaderCallbacks中包行onCreateLoader(), onLoaderReset(), onLoadFinished()三个接口。下面是它们的实现：</p>
<pre><code>@Override
public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
CursorLoader cursorLoader = new CursorLoader(
this,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
STORE_IMAGES,
null,
null,
null);
return cursorLoader;
}
@Override
public void onLoaderReset(Loader<Cursor> arg0) {
simpleCursorAdapter.swapCursor(null);
}
@Override
public void onLoadFinished(Loader<Cursor> arg0, Cursor cursor) {
simpleCursorAdapter.swapCursor(cursor);
}</code></pre><p>说明：<br>(01) onCreateLoader()会在初始化Loader之后执行，它的作用是返回一个Loader对象。<br>(02) 而onLoadFinished()是当异步加载完成之后会被执行，当Loader加载完数据时，我们会通过 simpleCursorAdapter.swapCursor(cursor)将simpleCursorAdapter切换到新的Cursor对象(即，加载完后保存数据的对象)。不同于changeCursor()，changeCursor()在切换到新的Cursor之后，会将旧的Cursor关闭掉；而swapCursor()切换到新的Cursor之后，不会关闭旧的Cursor，如果旧的Cursor存在的话，它会返回旧的Cursor。<br>(03) onLoaderReset()则是当异步加载起被重置时会被调用。当Loader被重置会，我们通过simpleCursorAdapter.swapCursor(null)将Cursor设为null。</p>
<h2 id="3-其他操作"><a href="#3-其他操作" class="headerlink" title="3. 其他操作"></a>3. 其他操作</h2><p>经过上面两步之后，已经能成功的使用异步加载数据了。得到的数据保存在SimpleCursorAdapter对象中，接下来需要做的就是在SimpleCursorAdapter中显示数据。</p>
<p>在onCreate()中，我们通过simpleCursorAdapter.setViewBinder(new ImageLocationBinder())设置了SimpleCursorAdapter的ViewBinder对象。下面看看ViewBinder中是如何显示的：</p>
<pre><code>// 将图片的位置绑定到视图
private class ImageLocationBinder implements ViewBinder {
@Override
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if (columnIndex == 1) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
String path = cursor.getString(column_index);
((TextView)view).setText("Location: "+path);
return true;
}
return false;
}
}</code></pre><p>至此，数据的异步加载示例差不多介绍完了。总的来说很简单，先获取LoaderManager对象，然后通过initLoader()初始化Loader。接着，需要作的是实现LoaderCallbacks接口！LoaderCallbacks接口中，需要重点关注的是onCreateLoader()和onLoadFinished()接口！</p>

<h1 id="Loader架构和原理"><a href="#Loader架构和原理" class="headerlink" title="Loader架构和原理"></a>Loader架构和原理</h1><p>在Loader简介中，我们大致介绍了Loader, LoaderManager各个类的作用。这里，我们分析一下它们的源码来查看它们是如何工作的。主要解决的有以下几个问题：<br>(01) <strong>Loader的异步加载原理。也就是说Loader异步是通过什么实现的？是一个Thread，还是AsyncTask，还是其他的什么方式</strong>？<br>(02) <strong>onCreateLoader()和onLoadFinished()是如何回调的。尤其是onLoadFinished()，当数据加载完时，是如何回调的</strong>？<br>(03) <strong>当发生Activity或Fragment被重新加载(例如，发生旋屏动作)时，Loader不会重新加载，它里面的数据仍然存在。这是如何做到的</strong>？<br>(04) <strong>Loader异步加载器，能够自动更新数据。它又是如何做到的</strong>？ </p>
<h2 id="1-异步加载原理"><a href="#1-异步加载原理" class="headerlink" title="1. 异步加载原理"></a>1. 异步加载原理</h2><p>涉及到的文件：<br>frameworks/base/core/java/android/app/LoaderManager.java<br>frameworks/base/core/java/android/content/Loader.java<br>frameworks/base/core/java/android/content/AsyncTaskLoader.java<br>frameworks/base/core/java/android/content/CursorLoader.java</p>
<h3 id="1-1-initLoader"><a href="#1-1-initLoader" class="headerlink" title="1.1 initLoader()"></a>1.1 initLoader()</h3><p>LoaderManager.java中initLoader()源码如下：</p>
<pre><code>public <D> Loader<D> initLoader(int id, Bundle args, LoaderManager.LoaderCallbacks<D> callback) {
if (mCreatingLoader) {
throw new IllegalStateException("Called while creating a loader");
}
LoaderInfo info = mLoaders.get(id);
if (DEBUG) Log.v(TAG, "initLoader in " + this + ": args=" + args);
if (info == null) {
// Loader doesn't already exist; create.
info = createAndInstallLoader(id, args, (LoaderManager.LoaderCallbacks<Object>)callback);
if (DEBUG) Log.v(TAG, " Created new loader " + info);
} else {
if (DEBUG) Log.v(TAG, " Re-using existing loader " + info);
info.mCallbacks = (LoaderManager.LoaderCallbacks<Object>)callback;
}
if (info.mHaveData && mStarted) {
// If the loader has already generated its data, report it now.
info.callOnLoadFinished(info.mLoader, info.mData);
}
return (Loader<D>)info.mLoader;
} </code></pre><p>说明：<br>(01) initLoader()会现通过mLoaders.get(id)来根据id获取LoaderInfo对象。如果Activity或Fragment第一次调用initLoader()，则获取到的LoaderInfo对象为null。<br>(02) 如果info为null，则执行createAndInstallLoader()来创建LoaderInfo对象。 </p>
<h3 id="1-2-createAndInstallLoader"><a href="#1-2-createAndInstallLoader" class="headerlink" title="1.2 createAndInstallLoader()"></a>1.2 createAndInstallLoader()</h3><p>LoaderManager.java中createAndInstallLoader()源码如下：</p>
<pre><code>private LoaderInfo createLoader(int id, Bundle args,
LoaderManager.LoaderCallbacks<Object> callback) {
LoaderInfo info = new LoaderInfo(id, args, (LoaderManager.LoaderCallbacks<Object>)callback);
Loader<Object> loader = callback.onCreateLoader(id, args);
info.mLoader = (Loader<Object>)loader;
return info;
}
private LoaderInfo createAndInstallLoader(int id, Bundle args,
LoaderManager.LoaderCallbacks<Object> callback) {
try {
mCreatingLoader = true;
LoaderInfo info = createLoader(id, args, callback);
installLoader(info);
return info;
} finally {
mCreatingLoader = false;
}
}
void installLoader(LoaderInfo info) {
mLoaders.put(info.mId, info);
if (mStarted) {
// The activity will start all existing loaders in it's onStart(),
// so only start them here if we're past that point of the activitiy's
// life cycle
info.start();
}
}</code></pre><p>说明：<br>(01) createAndInstallLoader()会分别调用createLoader()和installLoader()接口。<br>(02) createLoader()会新建LoaderInfo对象，然后调用callback.onCreateLoader()接口。<strong>这里的onCreateLoader()就是我们实现的LoaderCallbacks接口中的onCreateLoader()接口</strong>。<br>(03) initLoader()中会调用info.start()接口。 </p>
<h3 id="1-3-LoaderInfo中的start"><a href="#1-3-LoaderInfo中的start" class="headerlink" title="1.3 LoaderInfo中的start()"></a>1.3 LoaderInfo中的start()</h3><p>LoaderManager.java中的内部类LoaderInfo的源码如下：</p>
<pre><code>final class LoaderInfo implements Loader.OnLoadCompleteListener<Object>,
Loader.OnLoadCanceledListener<Object> {
final int mId;
final Bundle mArgs;
LoaderManager.LoaderCallbacks<Object> mCallbacks;
Loader<Object> mLoader;
...
public LoaderInfo(int id, Bundle args, LoaderManager.LoaderCallbacks<Object> callbacks) {
mId = id;
mArgs = args;
mCallbacks = callbacks;
}
void start() {
if (mRetaining && mRetainingStarted) {
mStarted = true;
return;
}
if (mStarted) {
return;
}
mStarted = true;
if (DEBUG) Log.v(TAG, " Starting: " + this);
if (mLoader == null && mCallbacks != null) {
mLoader = mCallbacks.onCreateLoader(mId, mArgs);
}
if (mLoader != null) {
if (mLoader.getClass().isMemberClass()
&& !Modifier.isStatic(mLoader.getClass().getModifiers())) {
throw new IllegalArgumentException(
"Object returned from onCreateLoader must not be a non-static inner member class: "
+ mLoader);
}
if (!mListenerRegistered) {
mLoader.registerListener(mId, this);
mLoader.registerOnLoadCanceledListener(this);
mListenerRegistered = true;
}
mLoader.startLoading();
}
}
...
}</code></pre><p>说明：start()中一个非常重要的成员是mLoader。<strong>它就是onCreateLoader()返回的Loader对象</strong>。start()会调用mLoaders.startLoading()。</p>
<h3 id="1-4-startLoading"><a href="#1-4-startLoading" class="headerlink" title="1.4 startLoading()"></a>1.4 startLoading()</h3><p>下面查看startLoading的相关代码。查看代码时，请记得：Loader.java, AsyncTaskLoader和CursorLoader这三者之间存在继承关系！</p>
<pre><code>// 在Loader.java中
public final void startLoading() {
mStarted = true;
mReset = false;
mAbandoned = false;
onStartLoading();
}
// 在CursorLoader.java中
@Override
protected void onStartLoading() {
if (mCursor != null) {
deliverResult(mCursor);
}
if (takeContentChanged() || mCursor == null) {
forceLoad();
}
} </code></pre><p>说明：startLoading()是在Loader.java中定义的，它调用了onStartLoading()。而CursorLoader.java覆盖了onStartLoading()函数。在onStartLoading()中，此时的mCursor是为null；所以，它会执行forceLoad()。</p>
<h3 id="1-5-forceLoad"><a href="#1-5-forceLoad" class="headerlink" title="1.5 forceLoad()"></a>1.5 forceLoad()</h3><p>下面查看forceLoad的相关代码。</p>
<pre><code>// 在Loader.java中
public void forceLoad() {
onForceLoad();
}
// 在AsyncTaskLoader.java中
@Override
protected void onForceLoad() {
super.onForceLoad();
cancelLoad();
mTask = new LoadTask();
if (DEBUG) Slog.v(TAG, "Preparing load: mTask=" + mTask);
executePendingTask();
}
// 在AsyncTaskLoader.java中
void executePendingTask() {
if (mCancellingTask == null && mTask != null) {
if (mTask.waiting) {
mTask.waiting = false;
mHandler.removeCallbacks(mTask);
}
if (mUpdateThrottle > 0) {
long now = SystemClock.uptimeMillis();
if (now < (mLastLoadCompleteTime+mUpdateThrottle)) {
// Not yet time to do another load.
if (DEBUG) Slog.v(TAG, "Waiting until "
+ (mLastLoadCompleteTime+mUpdateThrottle)
+ " to execute: " + mTask);
mTask.waiting = true;
mHandler.postAtTime(mTask, mLastLoadCompleteTime+mUpdateThrottle);
return;
}
}
if (DEBUG) Slog.v(TAG, "Executing: " + mTask);
mTask.executeOnExecutor(mExecutor, (Void[]) null);
}
}</code></pre><p>说明：forceLoad()会调用onForceLoad()。而onForceLoad()中会新建LoadTask对象，然后执行executePendingTask()。在executePendingTask()中会调用LoadTask对象的executeOnExecutor()。</p>
<h3 id="1-6-LoadTask"><a href="#1-6-LoadTask" class="headerlink" title="1.6 LoadTask"></a>1.6 LoadTask</h3><p>LoadTask是AsyncTaskLoader的内部类。实际上，它是AsyncTask的子类。在<a href="/2014/06/25/AsyncTask">介绍AsyncTask的文章中</a>，我们知道executeOnExecutor()会将任务提交到线程池中去执行，而这个被提交到线程池的任务会执行AsyncTask的doInBackground()。</p>
<pre><code>// AsyncTaskLoader.java中
final class LoadTask extends AsyncTask<Void, Void, D> implements Runnable {
private final CountDownLatch mDone = new CountDownLatch(1);
boolean waiting;
@Override
protected D doInBackground(Void... params) {
if (DEBUG) Slog.v(TAG, this + " >>> doInBackground");
try {
D data = AsyncTaskLoader.this.onLoadInBackground();
if (DEBUG) Slog.v(TAG, this + " <<< doInBackground");
return data;
} catch (OperationCanceledException ex) {
if (!isCancelled()) {
throw ex;
}
if (DEBUG) Slog.v(TAG, this + " <<< doInBackground (was canceled)", ex);
return null;
}
}
/* Runs on the UI thread */
@Override
protected void onPostExecute(D data) {
if (DEBUG) Slog.v(TAG, this + " onPostExecute");
try {
AsyncTaskLoader.this.dispatchOnLoadComplete(this, data);
} finally {
mDone.countDown();
}
}
...
}</code></pre><p>说明：LoadTask的doInBackground()会调用onLoadInBackground()。</p>
<h3 id="1-7-onLoadInBackground"><a href="#1-7-onLoadInBackground" class="headerlink" title="1.7 onLoadInBackground()"></a>1.7 onLoadInBackground()</h3><p>下面查看onLoadInBackground()的相关代码。</p>
<pre><code>// AsyncTaskLoader.java中
protected D onLoadInBackground() {
return loadInBackground();
}
// CursorLoader.java中
@Override
public Cursor loadInBackground() {
synchronized (this) {
if (isLoadInBackgroundCanceled()) {
throw new OperationCanceledException();
}
mCancellationSignal = new CancellationSignal();
}
try {
Cursor cursor = getContext().getContentResolver().query(mUri, mProjection, mSelection,
mSelectionArgs, mSortOrder, mCancellationSignal);
if (cursor != null) {
try {
// Ensure the cursor window is filled.
cursor.getCount();
cursor.registerContentObserver(mObserver);
} catch (RuntimeException ex) {
cursor.close();
throw ex;
}
}
return cursor;
} finally {
synchronized (this) {
mCancellationSignal = null;
}
}
} </code></pre><p>说明：loadInBackground()会执行查询。<strong>这就是后台任务真正执行的动作所在！</strong></p>
<p>至此，我们已经回答了第一个问题：Loader的异步加载原理。实际上，Loader的异步加载是通过AsyncTask启动一个后台任务，在后台任务中再执行query()查询操作！</p>
<h2 id="2-onLoadFinished是如何被回调的"><a href="#2-onLoadFinished是如何被回调的" class="headerlink" title="2. onLoadFinished是如何被回调的"></a>2. onLoadFinished是如何被回调的</h2><p>我们知道，当AsyncTask中的任务执行完时，会通过onPostExecute()反馈执行结果。下面，我们看看AsyncTask反馈的结果中是如何调用onLoadFinished()的。</p>
<h3 id="2-1-onPostExecute"><a href="#2-1-onPostExecute" class="headerlink" title="2.1 onPostExecute"></a>2.1 onPostExecute</h3><p>下面看看onPostExecute()的相关代码。</p>
<pre><code>// AsyncTaskLoader.java中
@Override
protected void onPostExecute(D data) {
if (DEBUG) Slog.v(TAG, this + " onPostExecute");
try {
AsyncTaskLoader.this.dispatchOnLoadComplete(this, data);
} finally {
mDone.countDown();
}
}
// AsyncTaskLoader.java中
void dispatchOnLoadComplete(LoadTask task, D data) {
if (mTask != task) {
if (DEBUG) Slog.v(TAG, "Load complete of old task, trying to cancel");
dispatchOnCancelled(task, data);
} else {
if (isAbandoned()) {
// This cursor has been abandoned; just cancel the new data.
onCanceled(data);
} else {
commitContentChanged();
mLastLoadCompleteTime = SystemClock.uptimeMillis();
mTask = null;
if (DEBUG) Slog.v(TAG, "Delivering result");
deliverResult(data);
}
}
}</code></pre><p>说明：onPostExecute()会执行dispatchOnLoadComplete()，而后者会调用deliverResult()来分发消息。</p>
<h3 id="2-2-deliverResult"><a href="#2-2-deliverResult" class="headerlink" title="2.2 deliverResult()"></a>2.2 deliverResult()</h3><pre><code>// CursorLoader.java中
@Override
public void deliverResult(Cursor cursor) {
if (isReset()) {
// An async query came in while the loader is stopped
if (cursor != null) {
cursor.close();
}
return;
}
Cursor oldCursor = mCursor;
mCursor = cursor;
if (isStarted()) {
super.deliverResult(cursor);
}
if (oldCursor != null && oldCursor != cursor && !oldCursor.isClosed()) {
oldCursor.close();
}
}
// Loader.java中
public void deliverResult(D data) {
if (mListener != null) {
mListener.onLoadComplete(this, data);
}
}</code></pre><p>说明：CursorLoader.java中的deliverResult()会通过super.deliverResult()调用父类的deliverResult()，也就是会执行Loader.java中的deliverResult()。最终会执行mListener.onLoadComplete()。mListener是什么呢？它是我们在执行LoaderManager.java的start()函数时，通过mLoader.registerListener(mId, this)注册到Loader上的。也就是说，mListener是LoaderManager中的LoaderInfo对象。</p>
<h3 id="2-3-LoaderInfo中的onLoadComplete"><a href="#2-3-LoaderInfo中的onLoadComplete" class="headerlink" title="2.3 LoaderInfo中的onLoadComplete()"></a>2.3 LoaderInfo中的onLoadComplete()</h3><pre><code>@Override

} finally {
if (mActivity != null) {
mActivity.mFragments.mNoTransactionsBecause = lastBecause;
}
}
mDeliveredData = true;
}
}</code></pre><p>说明：onLoadComplete()会调用callOnLoadFinished()，而callOnLoadFinished()最终会调用onLoadFinished()。<strong>这就是我们实现的LoaderCallbacks接口中的onLoadFinished()</strong>。</p>
<p>至此，我们也搞明白了第二个问题onLoadFinished()是如何被回调的。当AsyncTask任务执行完时，会调用onPostExecute()；而onPostExecute()会通过LoaderManager，LoaderManager最终会调用onLoadFinished()。</p>
<h2 id="3-当Activity或Fragment被重新加载时，Loader不会被重新加载。"><a href="#3-当Activity或Fragment被重新加载时，Loader不会被重新加载。" class="headerlink" title="3. 当Activity或Fragment被重新加载时，Loader不会被重新加载。"></a>3. 当Activity或Fragment被重新加载时，Loader不会被重新加载。</h2><p>这个原理其实非常简单，关键就是initLoader()的实现方式。</p>

@Override
public Cursor loadInBackground() {
synchronized (this) {
if (isLoadInBackgroundCanceled()) {
throw new OperationCanceledException();
}
mCancellationSignal = new CancellationSignal();
}
try {
Cursor cursor = getContext().getContentResolver().query(mUri, mProjection, mSelection,
mSelectionArgs, mSortOrder, mCancellationSignal);
if (cursor != null) {
try {
// Ensure the cursor window is filled.
cursor.getCount();
cursor.registerContentObserver(mObserver);
} catch (RuntimeException ex) {
cursor.close();
throw ex;
}
}
return cursor;
} finally {
synchronized (this) {
mCancellationSignal = null;
}
}
} </code></pre><p>说明：在执行query()查询之后，如果得到的Cursor对象不是null。则通过cursor.registerContentObserver(mObserver)来监听该cursor的内容。</p>
<h3 id="4-2-注册mObserver"><a href="#4-2-注册mObserver" class="headerlink" title="4.2 注册mObserver"></a>4.2 注册mObserver</h3><pre><code>// CursorLoader.java中
public CursorLoader(Context context) {
super(context);
mObserver = new ForceLoadContentObserver();
}
// CursorLoader.java中
public CursorLoader(Context context, Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
super(context);
mObserver = new ForceLoadContentObserver();
mUri = uri;
mProjection = projection;
mSelection = selection;
mSelectionArgs = selectionArgs;
mSortOrder = sortOrder;
}</code></pre><p>说明：在创建CursorLoader对象时，就创建了mObserver，它是ForceLoadContentObserver对象。</p>
<h3 id="4-3-ForceLoadContentObserver"><a href="#4-3-ForceLoadContentObserver" class="headerlink" title="4.3 ForceLoadContentObserver"></a>4.3 ForceLoadContentObserver</h3><pre><code>// Loader.java
public final class ForceLoadContentObserver extends ContentObserver {
public ForceLoadContentObserver() {
super(new Handler());
}
@Override
public boolean deliverSelfNotifications() {
return true;
}
@Override
public void onChange(boolean selfChange) {
onContentChanged();
}
}
// Loader.java中
public void onContentChanged() {
if (mStarted) {
forceLoad();
} else {
// This loader has been stopped, so we don't want to load
// new data right now... but keep track of it changing to
// refresh later if we start again.
mContentChanged = true;
}
}</code></pre><p>说明：ForceLoadContentObserver是Loader.java的内部类，它继承于ContentObserver。当数据发生变化时，它会回调onChange()，进而调用onContentChanged()。而onContentChanged()则会执行forceLoad()。forceLoad()在前面已经介绍过了，它会启动AsyncTask被执行query查询操作！</p>
<p>至此，几个问题都回答完了。Loader, AsyncTaskLoader, CursorLoader和LoaderManager的相互关系也整理完了！谢谢观赏！</p>

<h1 id="AsyncTask介绍"><a href="#AsyncTask介绍" class="headerlink" title="AsyncTask介绍"></a>AsyncTask介绍</h1><p>AsyncTask比Handler更轻量级一些，适用于简单的异步处理。</p>
<p>使用AsyncTask时，注意重写以下几个方法：</p>
<h2 id="1-doInBackground"><a href="#1-doInBackground" class="headerlink" title="1. doInBackground()"></a>1. doInBackground()</h2><p><strong>作用</strong>：执行后台任务。<br><strong>要求</strong>：必须重写！<br><strong>注意</strong>：在doInBackground()中不能进行UI操作！ </p>
<h2 id="2-onPreExecute"><a href="#2-onPreExecute" class="headerlink" title="2. onPreExecute()"></a>2. onPreExecute()</h2><p><strong>作用</strong>：通常用于执行后台任务开始前的准备动作。在用户调用execute()后，并且在AsyncTask主动执行doInBackground()之前被调用。<br><strong>要求</strong>：选择性重写。如果不重写该函数，默认不执行任何动作 </p>
<h2 id="3-onPostExecute"><a href="#3-onPostExecute" class="headerlink" title="3. onPostExecute()"></a>3. onPostExecute()</h2><p><strong>作用</strong>：通常用于处理后台动作的返回结果。在AsyncTask主动执行doInBackground()之前被调用。<br><strong>要求</strong>：选择性重写。如果不重写该函数，默认不执行任何动作 </p>
<h2 id="4-onProgressUpdate"><a href="#4-onProgressUpdate" class="headerlink" title="4. onProgressUpdate()"></a>4. onProgressUpdate()</h2><p><strong>作用</strong>：通常用于执行后台任务执行期间的进度更新。因为doInBackground()中不能操作UI，假如我们想在后台任务处理时显示进度，可以在doInBackground()中调用publishProgress()，而publicProgress()会调用onProgressUpdate()；在onProgressUpdate()中进行UI操作即可。<br><strong>要求</strong>：选择性重写。如果不重写该函数，默认不执行任何动作 </p>
<h2 id="5-onCancelled"><a href="#5-onCancelled" class="headerlink" title="5. onCancelled()"></a>5. onCancelled()</h2><p><strong>作用</strong>：通常用于执行取消AsyncTask任务时的相关动作。如果客户主动调用cancel()，则会执行onCancelled()；否则(AsyncTask执行完之后正常停止)，则不会调用onCancelled()。<br><strong>要求</strong>：选择性重写。如果不重写该函数，默认不执行任何动作 </p>
<p><a name="anchor2"></a></p>
<h1 id="AsyncTask使用和示例"><a href="#AsyncTask使用和示例" class="headerlink" title="AsyncTask使用和示例"></a>AsyncTask使用和示例</h1><p>下面是一个自定义的AsyncTask。</p>
<pre><code>private class MyTask extends AsyncTask<String, Integer, String> {
//onPreExecute方法用于在执行后台任务前做一些UI操作
@Override
protected void onPreExecute() {
Log.i(TAG, "onPreExecute");
textView.setText("loading...");
}
//doInBackground方法内部执行后台任务,不可在此方法内修改UI
@Override
protected String doInBackground(String... params) {
Log.i(TAG, "doInBackground");
try {
for (int i=0; i<6; i++) {
Log.d(TAG, "doInBackground: publishProgress="+i);
publishProgress(20*i);
Thread.sleep(500);
}
Log.d(TAG, "doInBackground: return OK!");
return "OK";
} catch (InterruptedException e) {
e.printStackTrace();
}
Log.d(TAG, "doInBackground: return FAIL!");
return "FAIL";
}
//onProgressUpdate方法用于更新进度信息
@Override
protected void onProgressUpdate(Integer... progresses) {
Log.i(TAG, "onProgressUpdate");
progressBar.setProgress(progresses[0]);
textView.setText("loading..." + progresses[0] + "%");
}
//onPostExecute方法用于在执行完后台任务后更新UI,显示结果
@Override
protected void onPostExecute(String result) {
Log.i(TAG, "onPostExecute");
textView.setText(result);
execute.setEnabled(true);
cancel.setEnabled(false);
}
//onCancelled方法用于在取消执行中的任务时更改UI
@Override
protected void onCancelled() {
Log.i(TAG, "onCancelled");
textView.setText("cancelled");
progressBar.setProgress(0);
execute.setEnabled(true);
cancel.setEnabled(false);
}
}</code></pre><p>说明：<br>(01) textView是一个TextView对象，cancel和execute分别是两个Button按钮，而progressBar则是进度条。<br>(02) 在任务开始时会通过onPreExecute()更新TextView的显示内容。<br>(03) 在任务结束时通过onPreExecute()更新TextView的显示内容。<br>(04) 任务执行过程中会通过publishProgress()更新进度条。<br>(05) 如果任务被强制取消的话，会将进度条重置为0。 </p>
<p>创建并执行AsyncTask的接口如下：</p>
<pre><code>mTask = new MyTask();
mTask.execute("http://www.baidu.com");</code></pre><p>取消AsyncTask的接口如下：</p>
<pre><code>mTask.cancel();</code></pre><p>点击查看：<a href="TODO">AsyncTask示例完整原理</a></p>
<p><a name="anchor3"></a></p>
<h1 id="AsyncTask原理"><a href="#AsyncTask原理" class="headerlink" title="AsyncTask原理"></a>AsyncTask原理</h1><p>下面通过Android4.4.2的AsyncTask源码来对AsyncTask原理进行介绍。</p>
<h2 id="1-AsyncTask构造函数"><a href="#1-AsyncTask构造函数" class="headerlink" title="1. AsyncTask构造函数"></a>1. AsyncTask构造函数</h2><pre><code>public AsyncTask() {
mWorker = new WorkerRunnable<Params, Result>() {
public Result call() throws Exception {
mTaskInvoked.set(true);
Process.setThreadPriority(Process.THREAD_PRIORITY_BACKGROUND);
//noinspection unchecked
return postResult(doInBackground(mParams));
}
};
mFuture = new FutureTask<Result>(mWorker) {
@Override
protected void done() {
try {
postResultIfNotInvoked(get());
} catch (InterruptedException e) {
android.util.Log.w(LOG_TAG, e);
} catch (ExecutionException e) {
throw new RuntimeException("An error occured while executing doInBackground()",
e.getCause());
} catch (CancellationException e) {
postResultIfNotInvoked(null);
}
}
};
}</code></pre><p>说明：</p>
<p>(01) mWorker是个WorkerRunnable对象，而WorkerRunnable是Callable的实现类。而在”<a href="http://www.cnblogs.com/skywang12345/p/3544116.html" target="_blank" rel="noopener">线程池中关于Callable的介绍</a>“时，我们说过，Callable类似于Runnable接口，不同之处主要在于Callable能和Future配合使用获取任务的结果，而Runnable不能获取结果！<br>(02) mFuture是FutureTask对象，而FutureTask洽洽是Future的实现类。 mWorker和mFuture配合使用，能获取后台任务的结果！ </p>
<h2 id="2-execute"><a href="#2-execute" class="headerlink" title="2. execute"></a>2. execute</h2><p>execute()的源码如下：</p>
<pre><code>public final AsyncTask<Params, Progress, Result> execute(Params... params) {
return executeOnExecutor(sDefaultExecutor, params);
}</code></pre><p>说明：sDefaultExecutor是线程池对象，而executeOnExecutor()是真正执行后台动作的地方。</p>
<p>下面是线程池相关的代码：</p>
<pre><code>private static final int CORE_POOL_SIZE = CPU_COUNT + 1;
private static final int MAXIMUM_POOL_SIZE = CPU_COUNT * 2 + 1;
private static final int KEEP_ALIVE = 1;
public static final Executor THREAD_POOL_EXECUTOR
= new ThreadPoolExecutor(CORE_POOL_SIZE, MAXIMUM_POOL_SIZE, KEEP_ALIVE,
TimeUnit.SECONDS, sPoolWorkQueue, sThreadFactory);
...
public static final Executor SERIAL_EXECUTOR = new SerialExecutor();
private static volatile Executor sDefaultExecutor = SERIAL_EXECUTOR;
private static class SerialExecutor implements Executor {
final ArrayDeque<Runnable> mTasks = new ArrayDeque<Runnable>();
Runnable mActive;
public synchronized void execute(final Runnable r) {
mTasks.offer(new Runnable() {
public void run() {
try {
r.run();
} finally {
scheduleNext();
}
}
});
if (mActive == null) {
scheduleNext();
}
}
protected synchronized void scheduleNext() {
if ((mActive = mTasks.poll()) != null) {
THREAD_POOL_EXECUTOR.execute(mActive);
}
}
}</code></pre><p>说明：该线程池是”通过双向队列实现的串行线程池”。scheduleNext()每次只会执行一个任务。</p>
<p>下面看看executeOnExecutor()的代码：</p>
<pre><code>public final AsyncTask<Params, Progress, Result> executeOnExecutor(Executor exec,
Params... params) {
if (mStatus != Status.PENDING) {
switch (mStatus) {
case RUNNING:
throw new IllegalStateException("Cannot execute task:"
+ " the task is already running.");
case FINISHED:
throw new IllegalStateException("Cannot execute task:"
+ " the task has already been executed "
+ "(a task can be executed only once)");
}
}
mStatus = Status.RUNNING;
onPreExecute();
mWorker.mParams = params;
exec.execute(mFuture);
return this;
}</code></pre><p>说明：<br>(01) executeOnExecutor()首先会对任务的状态进行处理。任务共三种姿态： </p>
<blockquote>
<p>PENDING: 挂起状态。当AsyncTask被创建时，就进入了PENDING状态。<br>RUNNING: 运行状态。当AsyncTask被执行时，就进入了RUNNING状态。<br>FINISHED: 完成状态。当AsyncTask完成(被客户cancel()或正常运行完毕)时，就进入了FINISHED状态。 </p>
</blockquote>
<p>当任务是RUNNING或PENDING状态时，会抛出异常。这就决定了，一个AsyncTask只能被执行一次，即只能对一个AsyncTask调用一次execute()；如果要重新执行任务，则需要新建AsyncTask后再调用execute()。<br>(02) 接着，调用onPreExecute()。这也就是任务执行前的准备动作！<br>(03) 然后，调用exec.execute(mFuture)。作用是将任务提交到线程池中进行执行。线程池的代码前面已经给出，SerialExecutor中的execute()会执行r.run()任务。r.run()实际上是调用FutureTask中run()方法，而FutureTask的run()方法，则会执行Callable的call()函数，即会执行到mWorker的call()方法。而观察前面mWorker的run()方法，我们会发现它会调用doInBackground()接口，并通过postResult()返回任务执行结果。而postResult()的内容如下： </p>
<pre><code>private static final InternalHandler sHandler = new InternalHandler();
private Result postResult(Result result) {
@SuppressWarnings("unchecked")
Message message = sHandler.obtainMessage(MESSAGE_POST_RESULT,
new AsyncTaskResult<Result>(this, result));
message.sendToTarget();
return result;
}
private static class InternalHandler extends Handler {
@SuppressWarnings({"unchecked", "RawUseOfParameterizedType"})
@Override
public void handleMessage(Message msg) {
AsyncTaskResult result = (AsyncTaskResult) msg.obj;
switch (msg.what) {
case MESSAGE_POST_RESULT:
// There is only one result
result.mTask.finish(result.mData[0]);
break;
case MESSAGE_POST_PROGRESS:
result.mTask.onProgressUpdate(result.mData);
break;
}
}
}</code></pre><p>说明：postResult()会发送MESSAGE_POST_RESULT给sHandler，而sHandler中会将任务执行结果传递给finish()。以下是finish()的代码：</p>
<pre><code>private void finish(Result result) {
if (isCancelled()) {
onCancelled(result);
} else {
onPostExecute(result);
}
mStatus = Status.FINISHED;
}</code></pre><p>说明：如果是正常执行结束，则调用onPostExecute()方法；否则(异常结束)，则调用onCancelled()方法。</p>
<p>至此，AsyncTask的原理结果完毕！总的来说，就是通过线程池来实现的，AsyncTask的任务会提交到线程池中，执行完后，线程池再返回结果。</p>

<p><a name="anchor1"></a></p>
<h1 id="ListPreference自定义属性"><a href="#ListPreference自定义属性" class="headerlink" title="ListPreference自定义属性"></a>ListPreference自定义属性</h1><p>系统自带的ListPreference的列表中只能显示文本。如果想显示图片或其他内容，只有通过自定义ListPreference的方式。</p>
<p>接下来，将通过示例来演示如何在ListPreference中显示图片。</p>
<p>点击查看：<a href="https://github.com/wangkuiwu/android_applets/tree/master/api_guide/app_components/fragment/preference_fragment/02_selfdeine_ListPreference_with_attr" target="_blank" rel="noopener">ListPreference示例的完整代码</a></p>
<h2 id="1-自定义属性"><a href="#1-自定义属性" class="headerlink" title="1. 自定义属性"></a>1. 自定义属性</h2><p>添加文件res/values/attrs.xml，内容如下：</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="IconListPreference">
<attr name="entryIcons" format="reference" />
</declare-styleable>
</resources></code></pre><p>说明：<br>(01) name=”IconListPreference”，与自定义的ListPreference类的名称相对应。后面会实现一个继承于ListPreference的IconListPreference.java。<br>(02) name=”entryIcons”，这是属性的名称。<br>(03) format=”reference”，这描述属性的值是引用类型。因为，后面会根据资源id设置该属性，所以将属性格式设为reference。如果是颜色，设为format=”color”；如果是布尔类型，format=”boolean”；如果是字符串，设为format=”string”。 </p>
<h2 id="2-自定义ListPreference"><a href="#2-自定义ListPreference" class="headerlink" title="2. 自定义ListPreference"></a>2. 自定义ListPreference</h2><h3 id="2-1-构造函数"><a href="#2-1-构造函数" class="headerlink" title="2.1 构造函数"></a>2.1 构造函数</h3><pre><code>public IconListPreference(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
// 获取自定义的属性(attrs.xml中)对应行的TypedArray
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.IconListPreference);
// 获取entryIcons属性对应的值
int iconResId = a.getResourceId(R.styleable.IconListPreference_entryIcons, -1);
if (iconResId != -1) {

}
// 获取Preferece对应的key

// 获取SharedPreferences.Editor
mEditor = mPref.edit();
// 获取Entry
// 注意：如果配置文件中没有android:entries属性，则getEntries()为空；
mEntries = getEntries();
// 获取Entry对应的值
// 注意：如果配置文件中没有android:entryValues属性，则getEntries()为空

// 设置Summary
if (mPosition!=-1) {
setSummary(mEntries[mPosition]);
setIcon(mEntryIcons[mPosition]);
}
a.recycle();</code></pre><p> } </p>
<p>说明：<br>(01) 首先，根据obtainStyledAttributes()能获取自定义属性对应的TypedArray对象。<br>(02) 在自定义属性中，entryIcons对应的类名是IconListPreference。因为需要通过”类名”_”属性名”，即IconListPreference_entryIcons的方式来获取资源信息。<br>(03) getKey()是获取Preferece对应的Key。该Key是Preference对象的唯一标识。<br>(04) getEntries()是获取Preferece的Entry数组。<br>(05) getEntryValues()是获取Preferece的Entry对应的值的数组。<br>(06) setSummary()是设置Preferece的summary标题内容。<br>(07) setIcon()是设置Preferece的图标。 </p>

<pre><code><?xml version="1.0" encoding="utf-8"?>

<p><a name="anchor1"></a></p>
<h1 id="ListFragment简介"><a href="#ListFragment简介" class="headerlink" title="ListFragment简介"></a>ListFragment简介</h1><p>ListFragment继承于Fragment。因此它具有Fragment的特性，能够作为activity中的一部分，目的也是为了使页面设计更加灵活。</p>
<p>相比Fragment，ListFragment的内容是以列表(list)的形式显示的。ListFragment的布局默认包含一个ListView。因此，在ListFragment对应的布局文件中，必须指定一个 android:id 为 “@android:id/list” 的ListView控件! </p>

<h1 id="Fragment创建方式"><a href="#Fragment创建方式" class="headerlink" title="Fragment创建方式"></a>Fragment创建方式</h1><p>Fragment有两种使用方式：静态方式 和 动态方式。</p>
<h2 id="1-静态方式"><a href="#1-静态方式" class="headerlink" title="1. 静态方式"></a>1. 静态方式</h2><p><strong>第一步</strong>：先定义一个Fragment子类。</p>
<pre><code>public class ExampleFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.example_fragment, container, false);
}
}</code></pre><p>说明：ExampleFragment是Fragment的子类，它的布局定义是example_fragment.xml文件。</p>
<p><strong>第二步</strong>：定义Fragment子类对应的布局文件。</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<EditText android:id="@+id/edit_message"

android:layout_height="wrap_content"
android:text="@string/button_send"
android:onClick="sendMessage" />
</LinearLayout></code></pre><p>说明：上面是example_fragment.xml的内容。</p>
<p><strong>第三步</strong>：在需要用到该Fragment的Activity对应的布局中使用该Fragment。</p>
<p>下面是引用Fragment的Activity的代码：</p>
<pre><code>public class FragmentLayoutTest extends Activity
{
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}</code></pre><p>下面是main.xml的内容：</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/fragment_intro"
/>
<fragment android:name="com.skw.fragmentlayouttest.ExampleFragment"
android:id="@+id/frag_example"
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout></code></pre><p>说明：在该布局文件中通过<fragment>调用了先前自定义的ExampleFragment。</fragment></p>

<h2 id="2-动态方式"><a href="#2-动态方式" class="headerlink" title="2. 动态方式"></a>2. 动态方式</h2><p>重复”上面的第一步和第二步”，实现一个Fragment子类。</p>
<p><strong>第三步</strong>：在需要用到该Fragment的Activity对应的布局中使用定义一个FrameLayout。</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"

>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/fragment_intro"
/>
<FrameLayout
android:id="@+id/frag_example"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout></code></pre><p><strong>第四步</strong>：在Activity中将Fragment填充到FrameLayout中。</p>
<pre><code>public class FragmentLayoutTest extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// 获取FragmentManager
FragmentManager fragmentManager = getFragmentManager();
// 获取FragmentTransaction
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
// 获取ExampleFragment
ExampleFragment fragment = new ExampleFragment();
// 将fragment添加到容器frag_example中
fragmentTransaction.add(R.id.frag_example, fragment);
fragmentTransaction.commit();
}
}</code></pre><p>点击查看：<a href="https://github.com/wangkuiwu/android_applets/tree/master/training/01_getting_started/05_fragments/implemention_02" target="_blank" rel="noopener">动态方式的完整源码</a></p>

<blockquote>
<p>实际上，Google官网关于Fragment的讲解内容包括三部分：创建Fragment，用Fragment创建灵活的UI，Fragments之间的通信。</p>
</blockquote>
<blockquote>
<ol>
<li>如何创建Fragment，我在上面已经详细介绍过了。 </li>
<li>灵活的创建UI，主要是指采用动态方式创建Fragment，并根据屏幕大小，来选择适当的Fragment对UI进行布局。 </li>
<li>Fragment之间的通信。Fragments之间是无法直接通信的，那怎么办呢？Google官网给出的解答是，采用类似于回调函数的机制。Fragment都是通过Acitivty来显示的，不同的Fragment可以通过Activity这个中介来进行通信。具体的做法是在Fragment给出接口定义，然后再在Activity中实现给接口，从而实现不同Fragment之间的通信。</li>

<blockquote>
<p>本章介绍会对Android的四大组建(Activity、Service、BroadcastReceiver、ContentProvider)中的Activity作概括性的介绍。</p>
</blockquote>
<p>首先，了解一下”什么是Activity”，Android中Activity的介绍如下：</p>
<blockquote>
<p>An activity is a single, focused thing that the user can do. Almost all activities interact with the user, so the Activity class takes care of creating a window for you in which you can place your UI with setContentView(). While activities are often presented to the user as full-screen windows, they can also be used in other ways: as floating windows (via a theme with windowIsFloating) or embedded inside of another activity (using ActivityGroup).</p>
</blockquote>
<p>从中，可以看出：<br> Activity 是用户接口程序，原则上它会提供给用户一个交互式的接口功能。它是 android 应用程序的基本功能单元。Activity 本身是没有界面的。所以activity类创建了一个窗口，开发人员可以通过setContentView(View)接口把UI放到activity创建的窗口上，当activity指向全屏窗口时，也可以用其他方式实现：作为漂浮窗口（通过windowIsFloating的主题集合），或者嵌入到其他的activity（使用ActivityGroup）。activity是单独的，用于处理用户操作。几乎所有的activity都要和用户打交道</p>
<p>接下来，我们将围绕Activity，依次介绍：<br>(1) Activity的生命周期<br>(2) Activity的启动方式和获取结果<br>(3) Activity的启动模式<br>(4) Activity和Application、进程之间的关系</p>

The Card and Board Game App
===========================
A web and Cordova app to play card and board games.
This app contains view-related code, which you can easily override, fork, or
entirely replace. For the core API and functionality, look at
https://github.com/lalomartins/cbga-core.
At some point before 1.0 (in fact, before 0.8), this will all be refactored
into packages; cbga:default-app will have routes, publishes, etc,
cbga:core-meteoric will have the Meteoric/Ionic views and layout, and any
game-specific game views will go to cbga:${game}-meteoric. There will be an API
for game-specific view packages to provide templates which game-neutral code
(your app, or cbga:core-meteoric) can look up via cbga:core, e.g.,
`{{> CBGA.view 'game'}}`.

* `Id`: this field distinguishes between initial Pairing messages (which follow the logic described in [Pairing](/apis/plegma/pairing-overview/)) and API messages. This is needed since unlike the rest of the supported protocols where HTTPS is used for the pairing procedure, here it is also carried out over Websockets
public enum eWSAPIType
{
Pairing = 1,
Api = 2
}
* `Subid`: a string that specifies the type of message being sent
* `Flags`: this field distinguishes between:
* Request-type messages (Get or Req) that mandate a response (Rsp or Set)
* Response-type messages to previous requests
* simple asynchronous messages
Specifically Flags is:
public enum eMsgFlags
{
None = 0, //async message
Request = 1, //message is request and expects response
Response = 2 //message is response to previous request
}
* `SyncId`:
* for a request that expects a response, this must be set to a non-zero, monotonically increasing number
* for a message that is a response to a previous request (Req or Get), this must be set to the original message's SyncId as previously described.
* for an async message the field should be ignored
* `Payload`: json-serialized payload being sent (same as in [Mqtt msg format](/apis/plegma/mqtt/message-format/))
