I'm new to Xamarin Forms and I'm trying to implement a page that contains a Map control with a user interface (buttons and clickable images) overlaid on top. I'm able to do this by putting the Map control in a StackLayout (full screen) and a layout that contains my user interface in to a RelativeLayout. This seems to work except I loose the ability to pan/zoom the underlying map. It would seem that my user interface (which doesn't have any pan/zoom handling) is blocking the gestures from the Map control. I've investigated implementing a MapRenderer but the user interface will include extensive user interactions which go beyond simply displaying icons, circles, polylines, etc. which the samples of MapRenderer do. Any ideas how I can do this?
