I need to display and move markers (representing friend’s locations) around in a mapview

  • 0

I need to display and move markers (representing friend’s locations) around in a mapview in Android 2.2.

At the moment I have extended ItemizedOverlay and OverlayItem, but I am not sure this is the best way to do it.

First of all should I have 1 ItemizedOverlay with many OverlayItem (one per marker) or each marker should have its own ItemizedOverlay? In case of the latter, should I extend Overlay instead?

Secondly, what is the best practice to move markers around? Destroy change point redraw? 😐

    In the end I am just using the ItemizedOverlay+OverlayItem structure.

    I am creating the overlay item on-the-fly in the createItem(int index) method, I suppose this is not the best solution (performance-wise) but anyways..
