VideoView 设置静音

                mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mp.setVolume(0f, 0f);
                        mp.start();
//                        mVideoView.start();
                    }
                });

 只要在mVideoView.setOnPreparedListener里设置 mp.setVolume(0f,0f)即可
