title: How can I add a button to a marker's info window?
body: <p>I would like to implement this in my app, but I have no idea of how to make the marker have a button, or how to have the OnMarkerClickListener tell me what part it clicked on.</p>
  
  <p>As an example, here is the official Maps app, where the directions icon is a separate part/button and the right side shows reviews.</p>
