How to perform zoom in/out on VideoView in android?

Found a tricky method to implement the same zooming methods used by all of the video player applications(mx player, vlc)

You can change the Videoview Layout params on the basics of screen width and height.

zoom++;
if (zoom == 1) {
    videoview1.setLayoutParams(new LinearLayout.LayoutParams(getDisplayWidthPixels(getApplicationContext()) + 500, getDisplayHeightPixels(getApplicationContext()) + 200));
    Toast.showMessage(getApplicationContext(), "1");
}
