title: ANDROID - ExpandableListView
body: <p>Im trying to figure out how to build a view that contains (many of):</p>
  
  <ul>
  <li>PARENT1 (checkable, expandable)</li>
  <li>CHILD1 (RADIO BUTTON)</li>
  <li>CHILD2 (RADIO BUTTON)</li>
  </ul>
  
  <p>...</p>
  
  <ul>
  <li>PARENT2 (checkable, expandable)</li>
  <li>CHILD1 (CHECKABLE)</li>
  <li>CHILD2 (CHECKABLE)</li>
  </ul>
  
  <p>...</p>
  
  <p>The point is that parent has to be checkable and based on that children have to change the icon. Can some1 point me into the right direction, because from what i found nothing seems to work for me.</p>
