ListView中获得滚动位置？ [英] ListView get scroll position?

问题描述

我使用的是MergeAdapter（马克·墨菲的出色一系列的项目）。你跟一个ListView使用它。我试图重建在刷新适配器的内容（而不是提神到位，并呼吁notifyDataSetChange（））。

I'm using a MergeAdapter (from Mark Murphy's excellent series of projects). You use it with a ListView. I'm trying to rebuild the contents of the adapter on a refresh (instead of refreshing "in place" and calling notifyDataSetChange()).

我想获得列表视图的y滚动值，所以我可以重置后，我重建我的名单。这似乎并不可能吗？

I'd like to get the y-scroll value of the listview so I can reset to that after I rebuild my list. This doesn't seem to be possible?

感谢

推荐答案

实施OnScrollListener您的列表视图。

Implement OnScrollListener for your listview.

@Override
public void onScroll(AbsListView absListView, int firstVisible, int visibleCount, int totalCount) { 
//firstvisible is your first visible item in the list
}
