title: How to inherit focus with android:duplicateParentState?
body: <p>I have a complex button which is made up of some layouts and Imagebuttons and then wrapped inside a Relativelayout for ease of use. The individual components work fine- I focus or click on one of the contained imagebuttons and it lights up as expected (drawable state list defines focus &amp; click states).</p>
  
  <p>Now I want this complex layout to behave as a unified button. I set </p>
  
  <pre><code>android:clickable="true" and android:focusable="true"
  </code></pre>
  
  <p>in the top-level layout. In all the sub-components I set </p>
  
  <pre><code>android:duplicateParentState="true" android:clickable="false" android:focusable="false". 
  </code></pre>
  
  <p>With this I get the expected behavior for touch cases- I touch the layout anywhere and all the contained components light up. However, focus does not work. Rolling the trackball now completely ignores the complex button.</p>
