title: android:layout_alignParentBottom is ignored when used without explicit layout height as a row in ListView
body: <p>When I use a <code>RelativeLayout</code> with either <code>fill_parent</code> or <code>wrap_content</code> as height and an element which specifies: <code>android:layout_alignParentBottom="true"</code> it is ignored and it is aligned at the top. Setting the height of the <code>RelativeLayout</code> to an explicit value makes it work. Any clues?</p>
