I'm using a MergeAdapter (from Mark Murphy's excellent series of projects). You use it with a ListView. I'm trying to rebuild the contents of the adapter on a refresh (instead of refreshing "in place" and calling notifyDataSetChange()).
I'd like to get the y-scroll value of the listview so I can reset to that after I rebuild my list. This doesn't seem to be possible?
Thanks

Okay, I found a workaround, using the following code: View c = listview. getChildAt(0); int scrolly = -c.
I used NotificationListener that is a widget that listens for notifications bubbling up the tree. Then use ScrollEndNotification , which indicates that scrolling has stopped. For scroll position I used _scrollController that type is ScrollController .
Since the MainActivity goes to onPause() -> onStop() method when the user clicked a list item, I am saving the state of ListView inside onPause(). For get the return Parcelable value I use a global variable called state.
Implement OnScrollListener for your listview.
@Override
public void onScroll(AbsListView absListView, int firstVisible, int visibleCount, int totalCount) {
//firstvisible is your first visible item in the list
}
