如何在片段中使用MediaPlayer到SurfaceView

Question

因为我希望能够通过播放视频的MediaPlayer,我想在播放视频的片段中使用SurfaceView而不是VideoView.

我查看了之前关于如何将MediaPlayer附加到SurfaceView的问题.这个问题的答案告诉我要创建两个函数:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_player);

    getWindow().setFormat(PixelFormat.UNKNOWN);
    mPreview = (SurfaceView)findViewById(R.id.surfaceView);
    holder = mPreview.getHolder();
    holder.setFixedSize(800, 480);
    holder.addCallback(this);
    holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
    mp = new MediaPlayer();
}


@Override
public void surfaceCreated(SurfaceHolder holder) {
    // TODO Auto-generated method stub
    mp.setDisplay(holder);
    play();
}

不幸的是,我不能通过Fragment覆盖surfaceCreated,因为Fragment没有这个方法.我还可以将MediaPlayer附加到片段中的SurfaceView吗？

使用回调侦听器将 Surface View 从 Fragment 传递到父 Activity，然后将 Media Player 从 Activity 连接到 Surface View，然后更新 Fragment Surface View，演示代码，IN Fragment

      SurfaceView mPreview ;

  private MyListener mylistener=null;
  public interface MyListener extends EventListener{
     void onPassSurface(SurfaceView surfaceview);
    }

   public void setListener (MyListener listener)
     {
        mylistener = listener;
      }

     public void updateSurfaceView(SurfaceView surfaceview)
      {
                  mPreview=surfaceview;

                 }

     mPreview =  (SurfaceView)findViewById(R.id.surfaceView);

     mylistener.onPassSurface(mPreview);

活动中

    MyFragment  myfragment=new MyFragmment();
    myfragment.setListener(new MyFragment.MyListener)
     {
       @Override
       void onPassSurface(SurfaceView mPreview)
         {
            //attach Media Player Here or Write Method to attach
            //media player with Surface View and Call from Here

            //after attaching media player call this method
              myfragment.updateSurfaceView(mPreview);
            }
