Android视频（VideoView）播放时没有音频

Question

I tried playing a wav file using mediaplayer and i can clearly hear it but when i tried playing a video, no sound heard.

code :

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.video_layout);
        videoView = (VideoView) findViewById(R.id.vdo);
        path = "android.resource://" +getPackageName() + "/raw/" +R.raw.video;
        videoView.setVideoURI(Uri.parse(path));
        videoView.setMediaController(new MediaController(this));
    }
    public void doPlayVid(View v){
        Log.d("path",path);
        switch(v.getId()) {
            case R.id.btn_video_play:
                videoView.start();
                break;
        }
    }

Thanks :)

You have to set volume of media player. You can do by first setting listener videoView.setOnPreparedListener(preparedListener); and then you can in method public void onPrepared(MediaPlayer m) { of preparedListener set desired volume m.setVolume(0f, 0f);

Example with inline listener:

videoview.setOnPreparedListener(new OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        mp.setVolume(0, 0);
    }
});
