NestedScrollView 和RV的滑动监听

嵌套监听 方法可用

  NoRootView.setOnScrollChangeListener((NestedScrollView.OnScrollChangeListener) (v, scrollX, scrollY, oldScrollX, oldScrollY) -> {
       if (scrollY > oldScrollY) {
           MyLog.e("向下滑动");
       }
       if (scrollY < oldScrollY) {
           MyLog.e("向上滑动");
       }
       if (scrollY == 0) {
           MyLog.e("滑动到顶部");
       }
       if (scrollY == (v.getChildAt(0).getMeasuredHeight() - v.getMeasuredHeight())) {
           MyLog.e("滑动到底部");
       }
   });
