title: dark action bar with Theme.AppCompat
body: <p>I am using <code>Theme.AppCompat</code> for my app to get the dark look. Everything looks good, except the action bar using this theme looks ancient i.e. it has a bright blue bottom divider.</p>
  
  <p>I want the action bar to look like it is in <code>Theme.AppCompat.Light.DarkActionBar</code>.</p>
  
  <p>Looking at <a href="https://android.googlesource.com/platform/frameworks/support/+/34bea73a6b2d6659f327272e4f482f9d86c1b592/appcompat/res/values/themes.xml" rel="noreferrer">themes.xml</a>, i find :</p>
  
  <pre><code>&lt;style name="Theme.AppCompat.Light.DarkActionBar"
         parent="Theme.Base.AppCompat.Light.DarkActionBar"&gt;
      &lt;item name="windowActionBar"&gt;true&lt;/item&gt;
  &lt;/style&gt;
  
  
  &lt;style name="Theme.Base.AppCompat.Light.DarkActionBar" parent="Theme.Base.AppCompat.Light"&gt;
      &lt;item name="actionBarDivider"&gt;@drawable/appcompat_divider_dark&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>So i create my own style as below :</p>
  
  <pre><code>&lt;style name="myTheme" parent="@style/Theme.AppCompat"&gt;
      &lt;item name="actionBarDivider"&gt;@drawable/appcompat_divider_dark&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>But i get the build error :</p>
  
  <pre><code>No resource found that matches the given name (at 'actionBarDivider' with value 
   '@drawable/appcompat_divider_dark')
  </code></pre>
  
  <p>Why can't i use the same drawable that is being used by the framework?</p>
