title: Unexpected effect of Holo Light Theme of my action bar
body: <p>I have used XML to define the Theme of the action bar for my Main activity to be as follows:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="@android:style/Theme.Holo.Light" /&gt;
  
  &lt;style name="HomeTheme" 
      parent="@style/AppTheme"&gt;
      &lt;item name="android:actionBarStyle"&gt;@style/HomeActionBarStyle&lt;/item&gt;
  &lt;/style&gt;
  
   &lt;style name="HomeActionBarStyle" 
      parent="@android:style/Widget.Holo.ActionBar"&gt;
      &lt;item name="android:displayOptions"&gt;showHome|showTitle&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Then in my Manifest file I have set the Theme of my activity with the defined Theme :</p>
  
  <pre><code>&lt;activity
  ....
  android:theme="@style/HomeTheme"
  ....
  &lt;/activity&gt;
  </code></pre>
  
  <p>everything went file as expected except two thing:
  1) the border line of the action bar area is still blue 
  2) the background color of the action bar area is white not grey.</p>
  
  <p>I am not sure what could be my mistake or this is just a bug in my emulator?
  I need to solve the previous two points just to have beautiful GUI</p>
