In case for some reason you don't want to call notifyDataSetChanged(), the you can maintain the position by using setSelectionFromTop()

Before updating the adaptor:

lastViewedPosition = listView.getFirstVisiblePosition();

//get offset of first visible view
View v = listView.getChildAt(0);
topOffset = (v == null) ? 0 : v.getTop();

After updating the adaptor:

listView.setSelectionFromTop(lastViewedPosition, topOffset);
