RecyclerView ScrollListener inside NestedScrollView

by

To achieve endless scrolling for recycler view which is under NestedScrollView, you can use “NestedScrollView.OnScrollChangeListener”

nestedScrollView.setOnScrollChangeListener((NestedScrollView.OnScrollChangeListener) (v, scrollX, scrollY, oldScrollX, oldScrollY) -> {
            if(v.getChildAt(v.getChildCount() - 1) != null) {
                if ((scrollY >= (v.getChildAt(v.getChildCount() - 1).getMeasuredHeight() - v.getMeasuredHeight())) &&
                        scrollY > oldScrollY) {
                        //code to fetch more data for endless scrolling
                }
            }
        });

Here v.getChildCount() -1 should give you the recycler view for which you be implementing endless scrolling.

Also scrollY > oldScrollY confirms that the page is being scrolled down.
