Refreshing data in RecyclerView and keeping its scroll position take user to the top of the activity

Question

I'm trying to implement app like Instagram where user can like and share but when he press on a button (like image heart) .

///interface to get position

@Override
public void onitemclick(int position) {

     position_of_image=position;
    int num1=uploads.get(position_of_image).getNumber_likes();
    uploads.get(position_of_image).setNumber_likes(num1+1);

   String id=uploads.get(position_of_image).getId();
   int number= uploads.get(position_of_image).getNumber_likes();
   String name= uploads.get(position_of_image).getName();
   String url=uploads.get(position_of_image).getImageUrl();

   //updating the tables

   Map<String,Object> map=new HashMap<>();
   map.put(id,new Upload(name,url,number,id));
//  mDatabaseRef.child(id).child("number_likes").setValue(number);
    uploads.clear();
    mDatabaseRef.updateChildren(map);
    mRecyclerView.smoothScrollToPosition(position_of_image);
}

**and this is my interface on click in my adapter I want to make the like btn is red it done but disappears quickly **

 @Override
        public void onClick(View v) {
        if (mlistener!=null){
            int position=getAdapterPosition();
            if (position!=RecyclerView.NO_POSITION){
                mlistener.onitemclick(position);

            }
           like.setImageResource(R.drawable.red_heart);

        }


public interface  onlikeclic{
        void onitemclick(int position);


    }
    public void setonitemclicklistener(onlikeclic listener){
        mlistener=listener;
    }

Answer 1

On item click, use call RecyclerView's smoothScrollToPosition(0) method.

You can see an example in this answer.
