ScrollViewRenderer Renderer

Hi this is the Android renderer code it works perfect in older Xamarin Forms but in 2.0 iam getting error at line 2 "Object Reference Not to set of instance of Object"

_scrollView = (HorizontalScrollView)typeof (ScrollViewRenderer)
                .GetField ("hScrollView", BindingFlags.NonPublic | BindingFlags.Instance)
                .GetValue (this);

            _scrollView.HorizontalScrollBarEnabled = false;
            _scrollView.Touch += HScrollViewTouch;

Please guide me if someone has the solution.

Thanks
