MapChange is an Android app that shows how to extend Google Maps' MapView class to get notifications when the map has been panned, zoomed or both.
To setup this project:
- Download a copy of this code.
/res/layoutto add your Google Maps API Key on this line:
Pan, zoom or pinch the map. The app will tell you what you just did (panned, zoomed or both).
Thanks to Dave Smith for suggesting the use of View.postDelayed instead of a timer so the change events are not launched on the timer's background thread. His wonderful suggestion has been incorporated in this code.
Thanks to Tobias for his patch to support map zooming via double tap.
