I had to make my VideoView sit in a RelativeLayout in order to make the chosen answer work.

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent">          <VideoView android:id="@+id/videoViewRelative"          android:layout_alignParentTop="true"          android:layout_alignParentBottom="true"          android:layout_alignParentLeft="true"          android:layout_alignParentRight="true"          android:layout_width="fill_parent"          android:layout_height="fill_parent">     </VideoView>      </RelativeLayout>
