Android : Stretch video to fill VideoView area

By default  Android will scale the video to fit the VideoView but keeping the video aspect ratio. That means that depending on the device's screen size there might be some black spaces left around the video the video since the it's not filling the screen.

VideoView doesn't provide an explicit way to specify the filling mode, you can achieve the same result by wrapping the video view in a Relative Layout and setting the VideoView alignments to match the parent's boundaries.
