title: Actionbarsherlock background image
body: <p>Having some trouble overriding ActionBarSherlock styles, hopefully someone can help.   I have created a drawable like so:</p>
  
  <p>(in res/drawable/actionbar_background.xml)</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;bitmap xmlns:android="http://schemas.android.com/apk/res/android"
      android:src="@drawable/bg"
      android:tileMode="repeat" /&gt;
  </code></pre>
  
  <p>Then in my app's style file (in res/values/style.xml)</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;style name="ActionBar" parent="@android:style/Widget.Holo.ActionBar"&gt;
      &lt;item name="android:background"&gt;@drawable/actionbar_background&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="my_theme" parent="@style/Theme.Sherlock.Light"&gt;
          &lt;item name="android:actionBarStyle"&gt;@style/ActionBar&lt;/item&gt;
      &lt;/style&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>The result is that the Theme.Sherlock.Light style is picked up (or Theme.Sherlock if I swap it), but I don't get any change in style to the actionbar's background itself.</p>
  
  <p>Thanks</p>
