If this data is related it should be in some common object or structure. So instead of "Brand[286] brands;" and "Grain[286] grains" you'd have "SingleObjectWithBothDataElements[268]" > If I chose, instead of a simple ListView, to migrate this to an > ExpandableListView (where group 1 would be individual brands), > would I need to split all of those arrays[1], or would I merely > add a list of brands, that would then point to ranges in the main > list?

So if I'm following your example, you'd have a list of brands as the top level list, then within each of those *each* would have a list of grains, or whatever the "children" are. I think you'd have a maintenance headache if you start doing some kind of crazy indexing into a giant array to determine the sub-lists. ------------------------------------------------------------------------------------------------- TreKing <http://sites.google.com/site/rezmobileapps/treking> - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
