因为直接使用系统vedioview，底部的MediaController布局有点不好看，尤其是进度条，不能实现办半屏与全屏的切换，自己网上看了下别人的资料，整理了下，做以笔记；初学者，勉强才实现这些功能，还有许多地方不明白。
看下效果：
1，MediaController.java.直接复制下系统源码的MediaController，来进行修改，就两个地方，一个布局相关的修改，以及进度条ProgressBar的修改，然后就 是添加了半屏与全屏的切换接口。

/**
* A view containing controls for a MediaPlayer. Typically contains the
* buttons like "Play/Pause", "Rewind", "Fast Forward" and a progress
* slider. It takes care of synchronizing the controls with the state
* of the MediaPlayer.
* <p>
* The way to use this class is to instantiate it programatically.
* The MediaController will create a default set of controls
* and put them in a window floating above your application. Specifically,
* the controls will float above the view specified with setAnchorView().
* The window will disappear if left idle for three seconds and reappear
* when the user touches the anchor view.
* <p>
* Functions like show() and hide() have no effect when MediaController
* is created in an xml layout.
*
* MediaController will hide and
* show the buttons according to these rules:
* <ul>
* <li> The "previous" and "next" buttons are hidden until setPrevNextListeners()
* has been called
* <li> The "previous" and "next" buttons are visible but disabled if
* setPrevNextListeners() was called with null listeners
* <li> The "rewind" and "fastforward" buttons are shown unless requested
* otherwise by using the MediaController(Context, boolean) constructor
* with the boolean set to false
* </ul>

3.VideoView.java，这个类，只是简单的把实现源码中MediaPlayerControl接口，修改为上面自己写的MediaController中的接口MediaPlayerControl即可，还有一处就是此类中onMeasure中注释掉那些解码大小的判断，直接采用当前默认大小，然后设置mSurfaceHolder.setFixedSize(width, height);这句若没写，全屏会失败，

4相关布局，media_controller.xml这个布局就是视频播放底部的布局，我这里是直接调整了下，加了全屏半屏切换按钮，自己有相关业务需要，可以来修改此布局，建议源码之前有的控件若无需要就先隐藏，不要删除，否则又得去修改MediaController类，此处不粘贴了，下面有demo下载；
activity_main.xml这布局就是在具体操作类中，全屏半屏的播放界面看下布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="@+id/toprl"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<com.example.vedioviewcompat.VideoView
android:id="@+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout
android:id="@+id/rl_dd"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="2" >
<TextView
android:id="@+id/dd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</RelativeLayout>
</LinearLayout>
5.在MainActivity.java中实现视频的播放，以及全屏半屏的切换，切换是通过让视频横屏和竖屏，来控制改变VideoView布局相对父布局情况来实现的，
public class MainActivity extends Activity implements onClickIsFullScreenListener {
private MediaController mController;
private boolean fullscreen=false;
private VideoView viv;
private ProgressBar progressBar;
private RelativeLayout rlDD;
private RelativeLayout rlTop;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
viv = (VideoView) findViewById(R.id.videoView);
rlDD=(RelativeLayout) findViewById(R.id.rl_dd);
// progressBar=(ProgressBar) findViewById(R.id.progressBar1);
mController = new MediaController(this);
mController.setClickIsFullScreenListener(this);
viv.setMediaController(mController);
// progressBar.setVisibility(View.VISIBLE);
viv.setVideoURI(Uri.parse("android.resource://" + getPackageName()
+ "/" + R.raw.apple));
viv.requestFocus();
viv.start();
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
return super.onTouchEvent(event);
}
@Override
public void setOnClickIsFullScreen() {
// TODO Auto-generated method stub
if(this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){//设置RelativeLayout的全屏模式
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}else{
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
}
public void onConfigurationChanged(Configuration newConfig) {
if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
Log.e("info", "横屏");
rlDD.setVisibility(View.GONE);
}else{
Log.e("info", "竖屏");
rlDD.setVisibility(View.VISIBLE);
}
super.onConfigurationChanged(newConfig);
viv.refreshDrawableState();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
本来想添加个视频加载ProgressBar，自己还没想出来，后续再整，
