title: How can I change the background of a text in action bar?
body: <p>I have an contextual Action Bar which appears when elements from a <code>ListView</code> are selected. </p>
  
  <p>It looks like this <a href="https://i.stack.imgur.com/NVbbS.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NVbbS.jpg" alt="enter image description here"></a></p>
  
  <p><code>Sample Text</code> is actually a button which <code>icon="@null"</code> and <code>title="Sample Text"</code>, which will do some stuff when clicked. How can I change the background of this button to another color, so that it gets more intuitive that it its actually a Button and not some text?</p>
  
  <p><em>(extra info)</em>
  The menu is inflated though an XML, which is this menu below</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"&gt;
      &lt;item
          android:id="@+id/menu_sample_text"
          android:icon="@null"
          android:orderInCategory="100"
          android:title="Sample Text"
          app:showAsAction="ifRoom|withText"/&gt;
  &lt;/menu&gt;
  </code></pre>
