android listview中复选框的状态

我想从列表视图中选择所有族id。我将家庭id添加到单独的 单击相应的复选框时显示arraylist。滚动列表视图时，arraylist中的值丢失

下面是我的代码

    public class FamilyList extends Activity{

对于（inti=0；i只需将以下代码移出if条件（if（v==null））：

只有在未获得要重用的视图时，才可以设置侦听器。但在重用现有视图时，仍然必须设置侦听器。因此，如果convertView不为null，则它已随旧onClickListener一起出现。此onClickListener使用了错误的位置（从旧视图）

因此，您不仅应该在（v==null）时设置OnClickListener。
我对代码做了一些更改，并将arraylist的实例（用于选定的\u ID）传递给它工作的适配器

以下是我的代码：
