title: How to add custom controls to MapFragment in Google Maps Android API v2?
body: <p>I have SupportMapFragment and I need to add custom controls into it for changing a map type. Calling getView(), I get NoSaveStateFramelayout and I don't think it is a good idea to add it directly into it or its children.</p>
  
  <p>What is the best way how can I can add a button over my map for changing the map type?</p>
