title: Change Android Dialog button text size via styles
body: <p>I am trying to enlarge the text size on all of my applications dialog buttons via styles.  The following code will change the buttons background colour and even the text case but for some reason the textSize item is not honoured:</p>
  
  <pre><code>&lt;style name="MyAppTheme" parent="@android:style/Theme.Holo"&gt;
      &lt;item name="android:dialogTheme"&gt;@style/MyApp.Dialog&lt;/item&gt;
      &lt;item name="android:alertDialogTheme"&gt;@style/MyApp.Dialog.Alert&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="MyApp.Dialog" parent="@android:style/Theme.Holo.Dialog"&gt;
      &lt;item name="android:borderlessButtonStyle"&gt;@style/MyApp.BorderlessButton&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="MyApp.Dialog.Alert" parent="@style/MyApp.Dialog"&gt;
      &lt;item name="android:windowBackground"&gt;@android:color/transparent&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="MyApp.BorderlessButton" parent="@android:style/Widget.Holo.Button.Borderless"&gt;
      &lt;item name="android:textSize"&gt;50sp&lt;/item&gt;
      &lt;item name="android:textAllCaps"&gt;true&lt;/item&gt;
      &lt;item name="android:background"&gt;#800&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>

  <p>Why is the textSize not being read?  What do I have to do to make it larger?</p>
