title: Cannot change the popupmenu color
body: <p>I am trying to change the color of a pop-up menu. 
   This is the code I am defining in the styles.xml:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
      &lt;!-- Customize your theme here. --&gt;
      &lt;item name="android:popupMenuStyle"&gt;@style/PopUp&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="PopUp" parent="@android:style/Widget.PopupMenu"&gt;
      &lt;item name="android:popupBackground"&gt;@color/test_color&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>p.s. my actionBar color is changed in java file, NOT is styles.xml
  Thank you!</p>
