title: Transparent Actionbar: custom tabcolor
body: <p>I want to create an ActionBar with tabs that are transparent, with <code>#3b000000</code>. Something like this, but with tabs below the ActionBar:</p>
  
  <p><img src="https://i.stack.imgur.com/lx4NY.jpg" alt="enter image description here"> </p>
  
  <p>This is the code I'm using in styles.xml:</p>
  
  <pre><code>&lt;style name="Theme.MyTheme" parent="@style/Theme.Sherlock.Light.DarkActionBar"&gt;
      &lt;item name="android:actionBarStyle"&gt;@style/ActionBar&lt;/item&gt;
      &lt;item name="windowActionBarOverlay"&gt;true&lt;/item&gt;
      &lt;item name="android:windowActionBarOverlay"&gt;true&lt;/item&gt;
      &lt;item name="actionBarStyle"&gt;@style/ActionBar&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="ActionBar" parent="@style/Widget.Sherlock.Light.ActionBar"&gt;
      &lt;item name="android:background"&gt;@color/actionbar&lt;/item&gt;
      &lt;item name="background"&gt;@color/actionbar&lt;/item&gt;
      &lt;item name="android:actionBarTabStyle"&gt;@style/ActionBarTabStyle&lt;/item&gt;
      &lt;item name="actionBarTabStyle"&gt;@style/ActionBarTabStyle&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="ActionBarTabStyle" parent="@style/Widget.Sherlock.ActionBar.TabView"&gt;
      &lt;item name="background"&gt;@color/actionbar_tabs&lt;/item&gt;
      &lt;item name="android:background"&gt;@color/actionbar_tabs&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>What happens, is that the ActionBar itself <em>does</em> show the transparent backgroundcolor, but the tabs are totally transparent (no color visible).</p>
  
  <p>How can I solve this?</p>
