title: ListView divider not applied when specified in style declaration
body: <p>This is more "Why?" than "How?" question, since I know a simple workaround for the problem. But I'd like to know what logic is behind behavior I'm going to describe.</p>
  
  <p>I've got a style declaraion and some ListViews. I want to change the way divider looks. I used following declaration:</p>
  
  <pre><code>&lt;style name="Theme.MyApp.Dark" parent="@style/Theme.Sherlock"&gt;
      &lt;item name="android:dividerHeight"&gt;4px&lt;/item&gt;
      &lt;item name="android:divider"&gt;#123456&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>To my amusement, only the height of the divider was applied. I've tried specifying color with alpha value (#12345678) and gradient drawable, nothing works. ListViews are declared like this:</p>
  
  <pre><code>&lt;ListView xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/list"  
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"/&gt; 
  </code></pre>
  
  <p>So, as you can see there's nothing that could override style declaration. I can change the divider only when I specify it directly in ListView declaration:</p>
  
  <pre><code>&lt;ListView xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/list"  
      android:divider="#123456"
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"/&gt; 
  </code></pre>
  
  <p>Using my newly-acquired skill of <a href="https://stackoverflow.com/questions/8630694/">specifying colors depending on theme selected</a>, I can work around this very easily - I will just have to declare <code>android:divider</code> with custom color attribute for every list.</p>
  
  <p>But why I can't change <code>android:divider</code> in the style, just like the <code>android:dividerHeight</code>? Is there some reason for that? I couldn't find an explanation, bug report or something similar that would let me understand this behavior.</p>
  
  <p>EDIT: The theme is applied globally, in the Manifest file:</p>
  
  <pre><code>&lt;application android:icon="@drawable/icon" android:label="@string/app_name" android:name="org.my.app" android:theme="@style/Theme.MyApp.Dark"&gt;
  </code></pre>
