Let me simplify this. Do you know of a Google example code you could point me to that shows a ListView with many items updating itself, without calling notifyDatasetChanged()? Where the items in the list are updating in real time? How is my View code supposed to know which list items are visible? Why should I be responsible for updating the cells if they aren't even on the screen? I'd need a pointer to all of the ListView subviews. Why isn't there simply a method on Adapter named, notifyDatasetChangedAtIndexes(int[] indexes), so that the ListView can be smart about merging the changes that I tell it about, with only the cells that are currently visible? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
