我的ListView自定义适配器（底座适配器）。我想通过位置获取视图列表视图从。我试过 mListView.getChildAt（位置），但它不工作。我怎样才能通过位置获取项目的看法？

I have listview with custom adapter (base adapter). I want to get view from listview by position. I tried mListView.getChildAt(position) , but it is not working. How can i get item view by position?

推荐答案

使用这样的：

public View getViewByPosition(int pos, ListView listView) {
    final int firstListItemPosition = listView.getFirstVisiblePosition();
    final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;

    if (pos < firstListItemPosition || pos > lastListItemPosition ) {
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        final int childIndex = pos - firstListItemPosition;
        return listView.getChildAt(childIndex);
    }
}
