Android: Video View: how to play a video on a loop

Use setLooping(true) on your MediaPlayer instance.

--Edit--

How about using setOnPrepareListener instead of setOnCompletionListener? This gives you access to the MediaPlayer object.

vv.setOnPreparedListener (new OnPreparedListener() {                    
    @Override
    public void onPrepared(MediaPlayer mp) {
        mp.setLooping(true);
    }
});

You Can take reference form below codes, Where setup_welcome_video is video file.

        myVideo = findViewById(R.id.VideoView);
        Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.setup_welcome_video);
        myVideo.setVideoURI(uri);
        myVideo.start();
        myVideo.requestFocus();
        myVideo.setOnPreparedListener (mp -> mp.setLooping(true));
