Hi, I found something that highlights Kostya solution including a trick to avoir header to appear selected:
http://thebogles.com/blog/2010/02/section-headers-for-android-listviews/ This seems straightforward to follow ... except that i can't get previous record. Unfortunately the isHeaderVisible(Cursor) method is not given :( I tried to use Cursor.moveToPrevious(), but that crashes on subsequent setViewValue call. I guessed I should not modify cursor within setViewValue() and try to restore cursor position before leaving the method, but that still crashes. Any clue?
