How to put a video above a background image using a VideoView?
<p>Is there any way to put a <code>VideoView</code> (which plays an MP4 file) above an image (which is the background of my app) ?</p>

<p>In other words, is there any way to put some transparency on my VideoView in the aim that the image be visible through the VideoView ?</p>

<p>Every time I try to put a <code>VideoView</code> over an <code>ImageView</code>, the <code>VideoView</code> hides a part of this <code>ImageView</code> (I tried to put an alpha on my <code>VideoView</code> but it doesn't work).</p>
