SurfaceView+MediaPlayer封装之路 SurfaceView+MediaPlayer封装之路我的播放器叫做JsPlayer，喜欢的话，就给个star喽^_^https://github.com/shuaijia/JsPlayer这里我只介绍播放器封装思路，会贴出部分代码，如果大家想查看完整代码，可以去github查看，有不清楚或错误或改进的地方，可以issues 我！写在之前先上效果图：（1.5版本新增弹幕功能）为什么要用Surface 阅读详情

代码如下：
public class MainActivity extends ActionBarActivity
{
private SurfaceView surfaceView;
private MediaPlayer player;
private SurfaceHolder holder;

@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
String uri="http://10.88.201.114:8080/GX_201601131948091593745624/transcodedmedia/video/Stream_v.m3u8 ";
player = new MediaPlayer();
try
{
player.setDataSource(uri);
holder=surfaceView.getHolder();
holder.addCallback(new MyCallBack());
player.prepare();
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
{
@Override
public void onPrepared(MediaPlayer mp)
{
player.start();

}
});
}
catch (IOException e)
{
e.printStackTrace();
}
}

private class MyCallBack implements SurfaceHolder.Callback
{
@Override
public void surfaceCreated(SurfaceHolder holder)
{
player.setDisplay(holder);
}

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height)
{

}

@Override
public void surfaceDestroyed(SurfaceHolder holder)
{

}
}

}
用机顶盒测试就是播不出视频，问一下原因。日志如下：
