title: How to make the header or footer of a ListView not clickable
body: <p>I'm adding a footer and header view to a <code>ListView</code> by using the methods <code>setHeaderView()</code> and <code>setFooterView()</code> and a <code>ViewInflater</code>. That works quite well. </p>
  
  <p>But how could I prevent the header or footer view from firing <code>onListItemClick</code> events? Of course I can catch the event and check whether it came from a header or footer, but this only solves one part of the problem, as header and footer got still focused when clicked. </p>
