我正在尝试在ExpandableListView的ItemTemplate中添加一个MvxLinearLayout，但是我收到了这个错误：
Cirrious.CrossCore.Exceptions.MvxException:
bindingContext is null during MvxAdapter creation - Adapter's should only be created
when a specific binding context has been placed on the stack
我怎样才能让它发挥作用？ 我是否必须使我的ExpandableListView类继承自另一个Mvx接口？
