android - listview 按位置获取项目视图 [英] android - listview get item view by position

问题描述

我有带有自定义适配器(基本适配器)的列表视图.我想按位置从列表视图中获取视图.我试过 mListView.getChildAt(position) ，但它不起作用.如何按位置获取项目视图?

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

使用这个:

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);
    }
}
