When I close the navigation drawer the scroll view moves down

When I close the navigation drawer the scroll view moves down. For example, if the current positionY is at the top of the scrollView, when I close the scroll view it moves it down to the middle/ near bottom. I tried doing this onCreate: 

ViewTreeObserver vto = scrollView.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            public void onGlobalLayout() {
                scrollView.scrollTo(scrollX, scrollY);
            }
        });

Although it works, 1. it doesn't go to the right position, 2. it doesn't do it right away. I can see it quickly goes down, and then it scrolls it up again. It is like a flash of it going up and down

I found the answer. I have a relative layout below the scroll view and put 

android:descendantFocusability="blocksDescendants"

Now it works
