Android，我试图在滚动gridView时隐藏textView，并在用户停止滚动时使其可见

Question

在下面的代码中，只调用onScroll方法并且永远不会调用onScrollStateChanged方法，请您帮我解决此问题：

mGridView.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {

            check_text.setVisibility(View.VISIBLE);

            System.out.println("Inside onScroll");
        }

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {

            if(scrollState == SCROLL_STATE_IDLE)
             {
                check_text.setVisibility(View.VISIBLE);  
                System.out.println("Inside onScrollStateChanged");
             }              
        }
    });
