Item inserted at first position is not visible until scrolling up

Question

Scenario:

• my adapter supports two different view types: A & B
• the adapter is notified about 100 items of type A - everything is rendered correctly
• the adapter is notified about one item of type B insertion using notifyItemRangeInserted at position 0 - this item is "invisible" by default and in order to see it I have to manually scroll up.

How can I get this first item of type B "automatically" visible?

Answer 1

You can use this line of code after notify item of type B:

yourRecyclerView.smoothScrollToPosition(0);

Answer 2

using https://stackoverflow.com/a/54899984/8144663 only wont resolve your issue.

You will need to call smoothScrollToPosition() in the next frame like,

recyclerview.post(new Runnable() {
            @Override
            public void run() {
                 recycleview.smoothScrollToPosition(n);
            }
        });
