How do use a MediaPlayer to a SurfaceView in a Fragment

问题:

Because I want to be able to pass the MediaPlayer that plays the video around, I want to use a SurfaceView instead of a VideoView inside my fragment that plays the video.

I looked at an earlier question about how to attach the MediaPlayer to the SurfaceView. The answer to the question tells me to create two functions:

@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(); } 

Unfortunately, I can't overwrite surfaceCreated via a Fragment because a Fragment doesn't have the method. Can I still attach MediaPlayer to a SurfaceView in a Fragment?

Pass Surface View From Fragment to parent Activity using Callback Listener and then attach Media Player from activity to surface View then update Fragment Surface View, demo code , 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); 

IN ACTIVITY

    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);             }
