title: Adding a button to a custom InfoWindowAdapter view that can register clicks
body: <p>I'm adding an InfoWindowAdapter with a custom layout to the Android Google Maps API v2 based map fragment. I've put a button in the view I return from getInfoWindow() and while it shows up perfectly fine, when I click on said button the window itself registers a click (blinking with a yellowish tint as usual) while the button does not.</p>
  
  <p>How can I make a button in the info window "clickable"? And, by extension, any view inside an info window?</p>
