Android: Change background color outside of the layout
<p>If I have my layout's width and height set to wrap_content, it will take up about half the screen.  If I set the layout's background to white, then only half the screen will be white while the other half remains on the default android black.  Is there a way to set this other half, which has no layout in it, to also be white?</p>

<p>I want to keep the layout's width set to wrap_content because I'm including it in several activities where it will be used in the top half of the screen but the bottom half will vary from activity to activity.</p>
