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);
    }
});
