title: Android NavigationView: How do I handle / disable selection of the header layout?
body: <p>I have a simple navigation drawer layout setup. I'm using the design support library so I have one a navigation view that slides in above the support library's toolbar. However, the header layout is responding to taps in the UI. I'm getting that ripple effect appearing behind the header layout when I tap it. How can I do either of the following:</p>
  
  <ol>
  <li>Disable the tap interaction all together? (so no ripple effect occurs)</li>
  <li>Respond to the tap interaction.</li>
  </ol>
  
  <p>I can't seem to find any documentation on this.</p>
