Set activity background in theme using a style?
<p>I want to use a background drawable for all my activities. How can I do this with a style?</p>

<pre><code>// styles.xml
&lt;style name="MyTheme" parent="Theme.Sherlock.Light.DarkActionBar.ForceOverflow"&gt;
    &lt;item name="android:background"&gt;@drawable/my_background&lt;/item&gt;  
&lt;/style&gt;
</code></pre>

<p>that sets the background for all widgets it seems. I just want it to work for activities.</p>

<p>Thanks</p>
