Alright just had a revelation on my drive home from the office... If there is no built-in functionality to handle this, here's what I plan on doing:
After a finger up event, start polling the map for it's centerpoint every 50ms or so and store the point in an instance variable. Check the stored centerpoint against each new centerpoint and if it's different, overwrite the store. Otherwise stop the timeout and we now know the panning is complete. The only problem I see with this is that from reading around the Web it seems that clicking on the zoom controls will fire a finger up event on the MapView... I haven't verified this behavior but others apparently have.. Two possible fixes I can think of: 1) Subclass the zoom controls [if possible] and override it to consume the event so finger up won't bubble to the MapView. 2) Don't worry about the event bubbling, but rather check if the View the finger up event was fired on is the zoom controls view or not. Any input before I try this out?
