title: How to change programmatically background color of action bar items
body: <p>It is easy to set a default color of the items background in action bar by setting:</p>
  
  <pre><code>&lt;item name="android:actionBarItemBackground"&gt;@drawable/action_bar_item_background&lt;/item&gt;
  </code></pre>
  
  <p>in application theme.</p>
  
  <p>I would like to change this color only for one of my fragments. How to do it programmatically?</p>
