[android-developers] Long press on the Google map secret?
Hello. For several days now can't find a solution how to handle a long press on Google map. I found a few detours: 1) Add GestureDetector as an overlay on the map 2) Do the calculation and determine a long time. But I don't understand why is not working OnLongClickListener if I ask for mapView, or define it in the class inherited from the ItemizedOverlay. Method onTouch works fine, but why didn't it work onLongClick -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Please, see my code. I speak that method onLongClick does not work. why does
not code work, i can not understand
public class MainItemizedOverlay extends ItemizedOverlay
implements OnLongClickListener{ private ArrayList mOverlayItems;
public MainItemizedOverlay(Drawable defaultMarker) {
super(boundCenterBottom(defaultMarker));mOverlayItems = new
ArrayList(); populate();
}
public void addNewItem(GeoPoint location, String markerText, String
snippet) { mOverlayItems.add(new OverlayItem(location, markerText,
markerText)); populate(); }
public void removeItem(int index) {
mOverlayItems.remove(index);populate(); }
@Override protected OverlayItem createItem(int index) {
return mOverlayItems.get(index);}
@Override public int size() { return
mOverlayItems.size();}
@Override public boolean onTouchEvent(MotionEvent event, MapView
mapView) { switch (event.getAction()) {case
MotionEvent.ACTION_DOWN: Log.i(MainMap.TAG, "Work");
break; case MotionEvent.ACTION_MOVE:
Log.i(MainMap.TAG, "Work"); break; case
MotionEvent.ACTION_UP: Log.i(MainMap.TAG, "Work");
break;
case MotionEvent.ACTION_CANCEL:
Log.i(MainMap.TAG, "Work"); break;
default:break; }
return super.onTouchEvent(event, mapView); }
public boolean onLongClick(View v) {Log.i(MainMap.TAG, "Do
not Work!! Why");return true;}}
