How to auto scroll up Recycler view in Android?

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.

If you want to take your user directly to the latest item without scroll animation then use this:

recyclerView.scrollToPosition(adapter.getItemCount()-1);

try with following method for auto scroll to any position....you can change argument of the "notifyItemChanged" method.

 public void printer(String message){
    block block=new block();
    block.details=message;

    blocks.add(block);

    blockAdapter.notifyItemChanged(0);
    recyclerView.scrollToPosition(blocks.size()-1);
   // recyclerView.scrollTo(blocks.size()-1,blocks.size());
}

On updating recyclerview try to run this code :

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

I use the following code so that the scroll is automatic until the last position:

recyclerView.smoothScrollToPosition(adapter.getItemCount());

I implement to add a new item to the list.

Try the bellow method for auto scroll to your particular position. 

adapter = new DeliveriesDateRecycleAdapter(getActivity(),sampleDatedate, position);
                recyclerviewDates.setAdapter(adapter);
                adapter.notifyDataSetChanged();
                recyclerviewDates.smoothScrollToPosition(position);

Note : position - the position of the list that you want to show.

Have you tried RecyclerView.srollTo(int x, int y)?

Edit: Try RecyclerView.scrollTo(0, 0) directly after you have send or received the last message.
