title: How can I get the ListView Header to be selectable?
body: <p>I have a Header added to my ListView.
  It appears fine, but no matter what I try, to get
  it to be selectable, nothing is working.</p>
  
  <p>Currently I'm doing:</p>
  
  <pre><code>hazardHeaderView =
      (View)getLayoutInflater().inflate(R.layout.warning_header, null);
  
  hazardHeaderView.setClickable(true);
  </code></pre>
  
  <p>And I have an <code>OnClickListener</code> set up for it,
  but the <code>Log</code> message I have there never gets called.</p>
  
  <p>What do I have to do to be able to detect that
  the user has clicked on the Header?</p>
  
  <p>I've tried several variations to the above
  but nothing's working.</p>
  
  <p>Thanks!</p>
