title: Replacement for ItemizedOverlay in Google maps V2 for Android?
body: <p>In V1 of Google Maps for Android I implemented a form of clustering using the ItemizedOverlay class. Each cluster has a center point (lat/lon), radius (in miles) and a count of the number of items in the cluster. I used ItemizedOverlay.draw(Canvas, MapView, shadow) to draw the clusters using Canvas object methods such as drawCircle() and drawText(). Each cluster consisted of a filled circle (sized according to the space required for the count) containing the count and a circle showing the radius.</p>
  
  <p>After reading the docs on V2 and playing with the demo app, I see no equivalent to ItemizedOverlay, and no obvious alternative. I suspect that the only way to do this is to maintain a list of clusters myself, and then subclass MapView and provide an implementation of its onDraw() method.</p>
  
  <p>Have I missed something in the V2 API that would be better than subclassing MapView?</p>
  
  <p>Thanks,</p>
