android - RecyclerView OnScrollStateChanged() 和 onScrolled()

Question

我的问题是，我们是否可以从 onScrollStateChanged() 方法中调用 RecyclerView 的 onScrolled() 方法。原因是我想检查两个条件。如果 SCROLL_STATE_SETTLING 为 true，则检查用户是否已向下滚动。还有其他方法可以检查两者吗？

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState);

            if (newState == RecyclerView.SCROLL_STATE_SETTLING) {

              // Now I have to check if the user has scrolled down or up.  

            }
        }

        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);


        }
    });
