[android-developers] Re: ListView with sections from a SINGLE Cursor

Ok, then I will probably stick with my current solution... if the
title has a solid background and is relatively small it all looks
pretty OK.
The only issue is the missing line under the title and the fact that
you can click the title to select the item below it.

The problem with your solution seems to be if you scroll directly to
the center of a large list, then you'd have to scan back to the
beginning to find the correct offset.
