在ExpandableListview 中，我在childview 中使用checkbox 和Imageview

为了管理 checkbox 的状态，我使用了 ArrayList 的回收属性

我无法找到错误发生的位置， 在这种情况下请帮助我

提前致谢

当我取消选中复选框时，我在 position_of_click.remove(childPosition); 行收到 IndexOutOfBoundsException

我想你的 position_of_click 变量是一个 ArrayList<Integer> 对象？

在这种情况下，请注意remove() 方法：您想使用remove(Object object)，而您正在使用remove(int index)。要强制您的代码使用 remove(Object object) 方法，您必须将参数转换为：

position_of_click.remove((Integer)childPosition);
