变量如下：
private SurfaceHolder mSurfaceHolder; private MediaPlayer mPlayer;
构造函数内获取 SurfaceHolder，并设置回调接口 Callback：
public MoviePlayerView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mSurfaceHolder = this.getHolder();
mSurfaceHolder.addCallback(mSurfaceHolderCallback); // holder加入回调接口
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);// setType必须设置，要不出错.
}
private Callback mSurfaceHolderCallback = new Callback() {
@Override
public void surfaceDestroyed(SurfaceHolder arg0) {
mSurfaceHolder = null;
}
@Override
public void surfaceCreated(SurfaceHolder arg0) {
// TODO Auto-generated method stub
mSurfaceHolder = arg0;
}
@Override
public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
mSurfaceHolder = arg0;
}
};
自定义视频播放成功回调接口：
/**
* 播放成功回调
* @date 2015-2-9
*/
public interface OnPlayCompletionListener{
public void onPlayCompletion();
}
通过设置 MediaPlayer 播放视频：
/**
* 播放视频
* @param fileName 文件路径
*/
public void play(String fileName, final OnPlayCompletionListener completionListener) {
mPlayer = new MediaPlayer();
mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mPlayer.setDisplay(mSurfaceHolder); // 定义一个SurfaceView播放它
mPlayer.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer arg0) {
stop();
if(completionListener != null)
completionListener.onPlayCompletion();
// canvas.drawColor(Color.TRANSPARENT,
// PorterDuff.Mode.CLEAR);
}
});
try {
mPlayer.setDataSource(fileName);
mPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mPlayer.start();
}
至此，主要代码已贴出，其实相比视频录制（请看另一篇 仿微信小视频录制控件），视频播放相对简单，相信童鞋们一下就可以看明白。
