title: Button style in AlertDialogs
body: <p>Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for <a href="http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/res/res/values/themes.xml;h=6b3d7407d1c895a3c297e60d5beac98e2d34c271;hb=HEAD" rel="noreferrer">themes</a> and <a href="http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/res/res/values/styles.xml;h=d7b654e49809cb97a35682754b1394af5c8bc88b;hb=HEAD" rel="noreferrer">styles</a> and experimented with different things but I haven't been able to find a way that works.</p>
  
  <p>What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. <code>myTheme</code> is applied to the whole <code>&lt;application&gt;</code> via the manifest. (Some other items were deleted for clarity, but they only relate to the title bar.)</p>
  
  <pre><code>&lt;style name="myTheme" parent="android:Theme"&gt;
      &lt;item name="android:buttonStyle"&gt;@style/customButtonStyle&lt;/item&gt;
      &lt;item name="android:alertDialogStyle"&gt;@style/dialogAlertTheme&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="dialogAlertTheme" parent="@android:style/Theme.Dialog.Alert"&gt;
      &lt;item name="android:fullDark"&gt;@drawable/dialog_loading_background&lt;/item&gt;
      &lt;item name="android:topDark"&gt;@drawable/dialog_alert_top&lt;/item&gt;
      &lt;item name="android:centerDark"&gt;@drawable/dialog_alert_center&lt;/item&gt;
      &lt;item name="android:bottomDark"&gt;@drawable/dialog_alert_bottom&lt;/item&gt;
      &lt;!-- this last line makes no difference to the buttons --&gt;
      &lt;item name="android:buttonStyle"&gt;@style/customButtonStyle&lt;/item&gt; 
  &lt;/style&gt;
  </code></pre>
  
  <p>Any ideas?</p>
