Don't try SetOnScrollChangeListener if you are working with android API below 21 (android M), you can try this :

yourScrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
            @Override
            public void onScrollChanged() {
                int rootHeight = yourScrollView.getHeight();
                int childHeight = yourScrollView.getChildAt(0).getHeight();
                int scrollY = yourScrollView.getScrollY();
                if(childHeight - rootHeight == scrollY)
                Log.d("Hei","You Have Reach The End!");
            }
        });
