runOnUiThread(new Runnable() {
                                public void run() {
                                    innerAdapter.notifyDataSetChanged();
                                }
                            });

but it not working. how can I solve it?

                            isEnable = true;
                            userChats.addAll(0, model.data);
                                                       innerChatAdapter.notifyDataSetChanged();
                            new Handler().postDelayed(new Runnable() {
                                @Override

                                    nnerChatAdapter.notifyItemInserted(0);
                                    recyclerView.smoothScrollToPosition(0);

Hello if you want to scroll down after add data to adapter.Add below method after notifyDataSetChanged() called.

 new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                mRecyclerView.smoothScrollToPosition(new_data_size);
            }
        }, 1);
