你可以创建内联匿名类并重写某些方法。你需要重写隐藏方法，否则在后面按控制器不会隐藏，并且活动不能关闭：

 mediaController = new MediaController(this){
        @Override
        public void hide() {
            // TODO Auto-generated method stub
            //do nothing
        }

        @Override
        public boolean dispatchKeyEvent(KeyEvent event) {

            if(event.getKeyCode() == KeyEvent.KEYCODE_BACK) {

                if (mediaPlayer != null) {
                    mediaPlayer.reset();
                    mediaPlayer.release();
                    mediaPlayer = null;
                }
                super.hide();
                Activity a = (Activity)getContext();
                a.finish();

            }
        return true;
        }
    };

你可以扩展MediaController类并以编程方式将其实例设置为VideoView类：

import android.content.Context;
import android.util.AttributeSet;
import android.widget.MediaController;

public class MyMediaController extends MediaController {
    public MyMediaController(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyMediaController(Context context, boolean useFastForward) {
        super(context, useFastForward);
    }

    public MyMediaController(Context context) {
        super(context);
    }

    @Override
    public void show(int timeout) {
        super.show(0);
    }

}

用法如下：

VideoView myVideoView = (VideoView) findViewById(R.id.my_video_view);
MediaController mc = new MyMediaController(myVideoView.getContext());
mc.setMediaPlayer(myVideoView);
myVideoView.setMediaController(mc);
