问题 I wanting to create an app which displays a map and on top of this map, the roads and points of interests will be painted as lines and ovals. These lines and ovals will have listeners attached to them so the user can drag them around or delete them. I am using openstreetmaps with osmdroid however it seems to be exactly the same as Google Maps. I was thinking of extending the OverlayItem class to represent a point of interest or a road.

问题 I've a mapView on which I managed to get an overlay onLongPress with the help of GestureListener. What I actually want is, I want to add markers (with same icon) one by one.

问题 till now i was using drawable to populate marker on my map .Now i was wondering it would be cool if i could display custom imageview as a marker in map. till now i am doing it like itemized= new Itemazide(drawable, mContext); i want to achieve something like 回答1: Yeah I was wondering if I could do something like this, i.e. show a custom View instead of drawable.
