设备不显示MediaController

Question

我使用下面的代码在仿真器和设备上测试，结果是，仿真器可以在VideoView下面显示MediaController (默认在屏幕底部)。但是，当我在设备中测试时，它没有显示MediaController。我想知道为什么。

final VideoView videoView = (VideoView)findViewById(R.id.videoGuide1);

    videoView.setOnPreparedListener(new OnPreparedListener(){
        @Override
        public void onPrepared(MediaPlayer mp){
            mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener(){
                @Override
                public void onVideoSizeChanged(MediaPlayer mp, int width, int height){
                    MediaController mediaController = new MediaController(WatchVideo.this);;
                    videoView.setMediaController(mediaController);
                    mediaController.setAnchorView(videoView);
                }
            });
        }
    });

Answer 1

试试这个，它对我很有效...

  VideoView vv;

        vv = (VideoView) findViewById(R.id.videoView);
        vv.setVideoPath(filename);
        vv.setMediaController(new MediaController(this));
        vv.requestFocus();
        vv.start();
  }

}

Answer 2

试试这条路

MediaController controller;
Videoview videoview;

videoview=(VideoView)findViewById(R.id.videoview);
controller = new MediaController(this);

videoview.setVideoURI(Uri.parse(path));
videoview.setMediaController(controller);
controller.setMediaPlayer(videoview);


videoview.setOnPreparedListener(new OnPreparedListener() {

           public void onPrepared(MediaPlayer mp) {
               int duration = videoview.getDuration();
               videoview.requestFocus();
               videoview.start();
               controller.show();

               Log.d("Video view is prepared","------>");

           }
       });
