title: Android AlertDialog remove divider between Button.Borderless in ButtonBar
body: <p>I am pretty much following <a href="http://blog.supenta.com/2014/07/02/how-to-style-alertdialogs-like-a-pro/" rel="nofollow noreferrer">this tutorial</a> and want to adapt the layout of the <code>AlertDialog</code> to my needs. Now I need to get rid of the divider between the two buttons in the <code>ButtonBar</code>. I changed the layout of my <code>Button</code> like this:</p>
  
  <pre><code>&lt;style name="Widget.Sphinx.Button.Borderless.Small" parent="@android:style/Widget.Holo.Button.Borderless.Small"&gt;
          &lt;item name="android:textColor"&gt;@color/button_textcolor&lt;/item&gt;
          &lt;item name="android:background"&gt;@drawable/button&lt;/item&gt;
          &lt;item name="android:layout_marginLeft"&gt;10dp&lt;/item&gt;
          &lt;item name="android:layout_marginRight"&gt;10dp&lt;/item&gt;
          &lt;item name="android:layout_marginBottom"&gt;10dp&lt;/item&gt;
          &lt;item name="android:gravity"&gt;center&lt;/item&gt;
          &lt;item name="android:textStyle"&gt;normal&lt;/item&gt;
          &lt;item name="android:dividerVertical"&gt;@android:color/transparent&lt;/item&gt;
   &lt;/style&gt;
  </code></pre>

  <p>I tried adapting the <code>ButtonBar</code> layout as well:</p>
  
  <pre><code>&lt;style name="Sphinx.ButtonBar.AlertDialog" parent="@android:style/Holo.ButtonBar.AlertDialog"&gt;
          &lt;item name="android:background"&gt;@android:color/transparent&lt;/item&gt;
          &lt;item name="android:dividerHorizontal"&gt;@null&lt;/item&gt;
          &lt;item name="android:dividerVertical"&gt;@null&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>I tried setting to <code>@null</code> and <code>@android:color/transparent</code> without success. What is the proper way to do this?</p>
