Question

My xml file:

Answer 1

We can look at VideoView source code:

SurfaceHolder.Callback mSHCallback = new SurfaceHolder.Callback(){
...
    public void surfaceCreated(SurfaceHolder holder)
    {
        mSurfaceHolder = holder;
        openVideo();
    }
    private void openVideo() {
        ...
        mMediaPlayer = new MediaPlayer();
        mMediaPlayer.setDisplay(mSurfaceHolder);
    }
}

So we can learn that we should use mediaplayer.setDisplay() in surfaceCreate method be called.
