You need to implement touch event on root view and for detecting scroll on scrollview you need to use below code

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() { @Override public void onScrollChanged() { int scrollX = rootScrollView.getScrollX(); //for horizontalScrollView int scrollY = rootScrollView.getScrollY(); //for verticalScrollView //DO SOMETHING WITH THE SCROLL COORDINATES } });
