title: Change action background color when selected (ActionBarSherlock)
body: <p>I want to change the color of the action background icon when it is pressed.</p>
  
  <p>I tried the following but no results:</p>
  
  <p><strong>styles.xml</strong></p>
  
  <pre><code>&lt;style name="Theme.Styled" parent="Theme.Sherlock.Light.DarkActionBar"&gt;
      &lt;item name="actionBarStyle"&gt;@style/Widget.Styled.ActionBar&lt;/item&gt;
      &lt;!-- &lt;item name="android:actionBarStyle"&gt;@style/Widget.Styled.ActionBar&lt;/item&gt; --&gt;
  &lt;/style&gt;
  
  &lt;style name="Widget.Styled.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse"&gt;
      &lt;item name="actionBarItemBackground"&gt;@drawable/action_item_background&lt;/item&gt;
      &lt;item name="selectableItemBackground"&gt;@drawable/action_item_background&lt;/item&gt;
  &lt;/style&gt; 
  </code></pre>
  
  <p><strong>action_item_background.xml</strong></p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
      android:shape="rectangle" &gt;
  
      &lt;solid android:color="#FF0000"/&gt;
  
  &lt;/shape&gt;
  </code></pre>
  
  <p>How can I achieve that?</p>
