Off the cuff, I'd try: Step #1: Modify the Section inner class of SectionedAdapter to hold an isEnabled boolean, with an appropriate constructor parameter Step #2: Modify SectionedAdapter#addSection() to take an isEnabled boolean and pass it to the Section constructor Step #3: Modify SectionedAdapter#isEnabled() to do a logical AND between the current logic (getItemViewType(position)!=TYPE_SECTION_HEADER) and the Section's isEnabled flag, for whatever Section corresponds to the supplied position > I've spent time looking > at the methods used for getItem(), getViewType(), and getView() which > seem to do similar things, but honestly don't quite understand what's > being done... Well, um, it's, er, explained in the book. :-) And if you've read the chapter and still don't understand, then I need to do a better job on that chapter. Upshot: SectionedAdapter implements a variant of the Aggregator pattern. It implements the Adapter methods in such a way that the Section for a given position determines what happens (e.g., what View goes with a given position). Right now, isEnabled() only needs to worry about whether or not the position corresponds to a heading -- in what you want to do, you need to also see what the Section thinks. Also, bear in mind that it *is* just a book example, designed to demonstrate a technique (in concert with the book itself). Use of this code in a nuclear power plant or heart monitor -- let alone a nuclear-powered heart monitor -- is not recommended... ;-) -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android App Developer Training: http://commonsware.com/training.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
