How to get the scrollposition in Recyclerview or the Layoutmanager?

I can measure the scrollposition by adding an OnScrollListener, but when the Orientation changes scrollDy is 0.

    mRecyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
            int scrollDy = 0;
            public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);

            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                scrollDy += dy;
How to&Answers:

You cannot get it because it does not really exist. LayoutManager only knows about the views on screen, it does not know the views before, what their size is etc.

The number you can count using the scroll listener is not reliable because if data changes, RecyclerView will do a fresh layout calculation and will not try to re-calculate a real offset (you’ll receive an onScroll(0, 0) if views moved).

RecyclerView estimates this value for scrollbars, you can use the same methods from View class.




These methods have their vertical counterparts as well.


For future use, If you are switching between Fragments within the same activity and all you want to do is save scroll-position for recyclerview and then restore recyclerview to the same scroll-position, you can do as follows:

In your onStop()/onDestroyView()/onPause() whatever callback is more appropriate, do this:

Parcelable recylerViewState = recyclerView.getLayoutManager().onSaveInstanceState();

And In your onStart()/onCreateView()/onResume() whatever callback is more appropriate, do this:


This way you can successfully keep your recyclerView's state in a parcelable and restore it whenever you want.


I came to the question just wanting to get the item position index that is currently scrolled to. For others who want to do the same, you can use the following:

LinearLayoutManager myLayoutManager = myRecyclerView.getLayoutManager();
int scrollPosition = myLayoutManager.findFirstVisibleItemPosition();

You can also get these other positions:

  • findLastVisibleItemPosition()
  • findFirstCompletelyVisibleItemPosition()
  • findLastCompletelyVisibleItemPosition()

Thanks to this answer for help with this. It also shows how to save and restore the scroll position.


recyclerView.computeVerticalScrollOffset() does the trick.


Found a work around to getting last scrolled position within the RecyclerView with credits to Suragch solution…
Declare a globally accessible LinearLayoutManager so a to be able to access it within inner methods…
When ever the populateChatAdapter method is called, if its the first call the scroll to position will be the last sent message and if the user had scrolled to view previous messages and method is called again to update new messages then they will retain their last scrolled to position…

LinearLayoutManager linearLayoutManager;
int lastScrollPosition = 0;
RecyclerView messages_recycler;

Initiate them…

messages_recycler = findViewById(R.id.messages_recycler);
linearLayoutManager = new LinearLayoutManager(this);

On your populate adapter method

private void populateChatAdapter(ObservableList<ChatMessages> msgs) {

    if (lastScrollPosition==0) lastScrollPosition = msgs.size()-1;
    ChatMessagesRecycler adapter = new ChatMessagesRecycler(msgs);
    messages_recycler.addOnScrollListener(new RecyclerView.OnScrollListener() {
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);
            lastScrollPosition = linearLayoutManager.findLastCompletelyVisibleItemPosition();


You have to read scrollDy in

public void onScrollStateChanged(RecyclerView recyclerView, int newState)

then you can get recyclerView's scroll position
