    private void setupContactsListView() {
        lst_addessbook.setOnScrollListener(new OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
//此处的firstVisibleItem就是最顶部的item的index
            }
        });
