RecyclerView does not change position to bottom element when adding new element

Question

I am creating a chat application and using RecyclerView.

This is the stack below.

When new messages appear. then we need to manually scroll this position.

It does not automatically change position like WhatsApp when new messages appear.

I used to use a ListView in which it works correctly.

Answer 1

Try it,

recyclerView.scrollToPosition(messages.size()-1); 

or

 recyclerView.setStackFromEnd(true) 

Answer 2

You can use the RecyclerView.scrollToPosition() function. Something like mRecyclerView.scrollToLastPosition(mAdapter.getCount()-1)
