如何使用 OnItemClick 刷新 ListView 中单行的内容

发布于 2024-11-28 17:25:43 字数 547 浏览 1 评论 0原文

我有一个带有复选框的列表视图。我想要实现的是一个 onItemClick （在我的活动中），如果我单击该行，它会检查/选择我的复选框，如下所示：

@Override
public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
    MyItem row = ListofRows.get(position);
    row.setSelected(true);
    myAdapter.notifyDataSetChanged();
}

当我单击该行时，由于方法 notifyDataSetChanged( )

问题是：此方法会刷新整个 ListView，因此，即使用户位于列表的底部，ScroolBar 也会转到开头（用户被驱动到列表的标题）这列表。

我需要的是：仅刷新这一单击的行，这样用户就不会被带到列表的开头。

这个问题有什么解决办法吗？

原文

I have a ListView with a CheckBox.
What I am trying to implement is an onItemClick (in my activity) that check/select my CheckBox if I click on the row, as you can see below:

@Override
public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
    MyItem row = ListofRows.get(position);
    row.setSelected(true);
    myAdapter.notifyDataSetChanged();
}

When I click in the row, the ListView is refreshed because of the method notifyDataSetChanged()

THE PROBLEM IS: this method refreshes the whole ListView and as a result, the ScroolBar goes to the beginning (the user is driven to the header of the list) even if the user is at the bottom of the list.

WHAT I NEED IS: Refresh just this single clicked row so the user won't be driven to the beginning of the list.

Are there any solutions to this problem?
