title: Change Dialog Theme for every Dialog
body: <p>Im using Theme.Holo.Light.DarkActionBar but I dont really like the Light Dialogs/AlertDialogs.</p>
  
  <p>I want to change every Dialog to the dark Holo Dialog.</p>
  
  <pre><code>&lt;style name="CustomDialogTheme" parent="@android:style/Theme.Holo.Dialog"&gt;
      &lt;item name="@android:background"&gt;#9933CC&lt;/item&gt;
      &lt;item name="@android:textColor"&gt;#02FA07&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="Holo.Light.DarkActionBar" parent="@android:style/Theme.Holo.Light.DarkActionBar"&gt;
      &lt;item name="android:dialogTheme"&gt;@style/CustomDialogTheme&lt;/item&gt;
      &lt;item name="android:alertDialogStyle"&gt;@style/CustomDialogTheme&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>Thats what I tried but it has no effect on any Dialogs.</p>
