Android ListView y position

Question

It seems like ListView doesn\'t expose its y-position in the same way a ScrollView does. In other words: I need to remember the exact position the ListView was scrolled to

Answer 1

When you are returning from another Activity, the ListView will remain scrolled to its original position that it was at when you left that ListView Activity. If you are updating the contents of the list make sure you just use notifyDataSetChanged() on the adapter, do not re-assign the adapter - this will reset the list to the top.

Check your onResume method in your ListView Activity, it might be re-assigning a list adapter.

If you need to remember an arbitrary scroll position that doesn't rely on the Activity stack, I am willing to bet that isn't possible besides just saving the current selected or first visible item. A ListView does not have a defined height. It is relative to both the number of items and content of those items.
