I haven't done line drawing in the map view, but probably just one. Override draw(), call super.draw() to do the default drawing and then to draw your lines however that's done.

I was under the impression you were drawing these points / lines on your own, but now I see you're using ItemizedOverlay. I would expect the ItemizeOverlay class to be optimized for this sort of thing already (i.e., the map would not draw overlay items that are not in the view), so I think doing a bounds check yourself might be overkill, and may in fact make things worse if you do it every time draw is called. Of course I don't know the implementation details of the ItemizedOverlay class to know for certain. I would do as others have suggested and keep track of when the view changes (on zooming or panning basically) and needs to be updated. When this happens, in the draw() call then and only then would you need to update your list of items to draw. ------------------------------------------------------------------------------------------------- TreKing - Chicago transit tracking app for Android-powered devices http://sites.google.com/site/rezmobileapps/treking -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
