RecyclerView-How to know if there is 5 items to scroll?

I load data from internet and i'm doing pagination.

I use this code to load more data:

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);
            if(!recyclerView.canScrollVertically(1)&&loading==false&&postson==false){
                loading=true;
                lastitem+=20;
                loaddata(lastitem);

            }
        }


    });

But this only works when recycler view reachjes the bottom and i think this might confuse the user. I want to load more data when 5 item left.

How to do that?

Check the item count of the layout Manager (make your layout manager global), probably linear layout manager then from there compare the two Like this:

    @Override
    public void onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
        super.onScrolled(recyclerView, dx, dy)
        if (!isRequesting) {
            int visiblePicturePosition = linearLayoutManager.findLastVisibleItemPosition()
            int totalItems = linearLayoutManager.getItemCount()
            if (totalItems - visiblePicturePosition <= 5) {

                //Do what you want here
        }
    }
