I have created a MapActivity containing a MapView. Drag and zoom work fine, and I've successfully added an ItemizedOverlay that displays and updates properly. Right now I can add OverlayItems to the map center via a button, but I would like to add functionality allowing the user to issue a long click to add an OverlayItem to the map at the selected location.
My first attempt was to use setLongClickable(true) and setOnLongClickListener, but that doesn't provide the click location. The only param it receives it the View object, but I couldn't find any way to determine the location of the click event. My second attempt was to use setOnTouchListener. This seems completely broken to me. If I return true (ie, consume event) I continue getting all touch events, but drag and zoom of the MapView do not work. That seems like expected behavior. If I return false (ie, do not consume the event) the map view continues to work correctly. My listener receives ONLY the first touch event. Stepping through in debug, it looks like MapView.mOnTouchListener gets set to something like ZoomListener (that's not the exact name, but it's close to that) and then to null shortly after my listener is invoked. Is there another preferred way of handling touch events in MapView? I was able to work around it by extending MapView and overriding onTouchEvent(). I found that if I used MapView.setOnTouchListener() directly, MapView itself would call setOnTouchListener(), discarding my listener and replacing it with a zoom listener. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
