Android VideoView in full screen maintains aspect ratio

I am working with a splash screen in my application. I would like to have a background video in it. My video is 1280x720 and it should be in full screen portrait mode.

My code works, but then it stretches the height of the video.

What I want is to get it centered while the height is 100% on screen.

VideoView videoview = (VideoView) findViewById(videoView);
Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.splash);
videoview.setVideoURI(uri);
videoview.start();
