Don't call super.draw(), instead iterate over your list of OverlayItems and
draw a circle at their locations. This is where deriving your own
OverlayItem class would be helpful if the radius of the circle varies for
each item. So simply:
void draw(...)
{
for (OverlayItem item : items)
drawCircle(item, ...);
}
Where drawCircle draws a circle for the given item, obviously. That's pretty
straightforward (look at the Canvas and use the Projection to convert
distance to pixels).

I don't know what you mean your method "clears". Any part of the view that
needs to be redrawn will be completely cleared and redrawn, which will call
your draw method. You shouldn't have to do anything more than what I've
posted above.
