Answer by Sasha Shpota for MediaController positioning over VideoView

With java 8:

videoView.setOnPreparedListener(mediaPlayer ->
    mediaPlayer.setOnVideoSizeChangedListener(
        (player, width, height) -> {
            MediaController controller = new MediaController(YourActivity.this);
            videoView.setMediaController(controller);
            controller.setAnchorView(videoView);
        }
    )
);
