Can't get rid of bottom padding on button
<p>I have a button. It seems to have bottom padding I cannot get rid of:</p>

<pre><code>&lt;Button
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:text="Foo"/&gt;
</code></pre>

<p>In the resource editor, I can click the button, and you see the padding below the bottom edge of the button there. This seems to block me from properly centering the button vertically in a parent RelativeLayout.</p>

<p>I tried setting padding=0dip and layout_margin=0dip, no effect. That bottom padding persists.</p>

<p>Thanks</p>
