Re: [android-developers] getting clicks on a map view
Using Mark Murphy's online books, he describes how to do this. I don't know if it is the only way, but basically you extend ItemizedOverlayOverlayItem, in the constructor you do the items.add(OverlyaItem) method call. This will add overlayitem's to the map. These items are clickable and you can implement the click handler in the OverlayItem extending class that you provide/add. I recommend his books. He responds here a lot and has his own forum and weekly chats as well. Well worth $40.

Re: [android-developers] getting clicks on a map view
Glad it worked out. Curious.. the overlayitem stuff seems to work pretty well.. why would you need to be able to control clicks directly on the map at any point, instead of providing overlayitems?

Re: [android-developers] getting clicks on a map view
because my MapView is embedded in a much more complex view that's inside a scroller. rather than fight the ScrollView by allowing clicks in the embedded map, i just trap clicks on it and open up the Maps application. Glad it worked out. Curious.. the overlayitem stuff seems to work pretty well.. why would you need to be able to control clicks directly on the map at any point, instead of providing overlayitems?
