How to auto scroll up Recycler view in Android?

Question

I have developed some chat application where i can send and received messages. But the problem is whenever i send or receive messages the recycler view is not scrolling to top so that messages gets diplayed above the keypad.

I have used the above mentioned recycler view android.support.v7.widget.RecyclerView.

Answer 1

On updating recyclerview try to run this code :

recyclerView.post(new Runnable() {
    @Override
    public void run() {
        // Call smooth scroll  
        recyclerView.smoothScrollToPosition(adapter.getItemCount() - 1);                                 
    }
});
