Mute a playing video by VideoView in Android Application

If you want to get access to the MediaPlayer of a VideoView you have to call MediaPlayer.OnPreparedListener and MediaPlayer.OnCompletionListener, then you can call MediaPlayer.setVolume(0f, 0f); function to set the volume to 0.

Do this:

@Override

public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_video);

  VideoView videoView = (VideoView)this.findViewById(R.id.VVSimpleVideo);
  MediaController mc = new MediaController(this);
  mc.setAnchorView(videoView);
  mc.setMediaPlayer(videoView);
  videoView.setMediaController(mc);
  String _path = "/mnt/sdcard/Movies/video5.mp4";

  videoView.setVideoPath(_path);
  videoView.setOnPreparedListener(PreparedListener);

  videoView.requestFocus();

  //Dont start your video here
  //videoView.start();


}

MediaPlayer.OnPreparedListener PreparedListener = new MediaPlayer.OnPreparedListener(){

     @Override
     public void onPrepared(MediaPlayer m) {
         try {
                if (m.isPlaying()) {
                    m.stop();
                    m.release();
                    m = new MediaPlayer();
                }
                m.setVolume(0f, 0f);
                m.setLooping(false);
                m.start();
            } catch (Exception e) {
                e.printStackTrace();
            }    
     }
 };
