我有一个BaseExpandableListAdapter（代码如下），它操作一个ExpandableListView和一个名为Checklist的模型。
清单模型包含类别列表。
类别是检查列表。
检查是一个低的列表。
Low包含一个布尔值项，由视图中的复选框表示。
我使用ViewHolder模式来处理我的模型：CategoryViewHolder用于我的GroupView，CheckViewHolder用于我的ChildView。
我遇到的问题是，在getChildView方法中，**当我选择Low中的一个复选框（在Check中）并向下滚动时，我发现另一个复选框被选中。**当我在Check中的edittext对象中写入内容并滚动时，会发生同样的事情，另一个edittext被编辑。
我怀疑我的vue回收是不能正常工作，但我还没有找到任何解决方案。
有什么想法吗
