Diffutil in recycleview, making it autoscroll if a new item is added

Question

If we use DiffUtil.Callback, and do

adapter.setItems(itemList);
diff.dispatchUpdatesTo(adapter);

how can we make sure that ad

Answer 1

I used RecyclerView.AdapterDataObserver to detect when new items were added, and then scroll to the top of my list;

adapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
    @Override
    public void onItemRangeInserted(int positionStart, int itemCount) {
        super.onItemRangeInserted(positionStart, itemCount);
        recycleView.smoothScrollToPosition(0);
    }
});
