推荐答案

如果使用的是BaseExpandableListAdapter，则可以覆盖方法getChildTypeCount()和getChildType().然后，您可以在getChildView()中填充匹配的布局，然后参数convertView始终是正确的类型.

If you're using a BaseExpandableListAdapter, you can override the methods getChildTypeCount() and getChildType(). Then you can inflate your matching layout in getChildView(), the parameter convertView will then always be of the correct type.

在您的示例中，getChildTypeCount()将返回5，而getChildType()仅返回groupId.

In your example, getChildTypeCount() would return 5 and getChildType() could simply return the groupId.
