在什么条件下getChildView（）被调用ExpandableListAdapter [英] On what conditions getChildView() is called in ExpandableListAdapter

问题描述

在我的应用程序， getChildView（）在我的 ExpandableListAdapter 不会被调用，而适配器返回正确的子计数（当 getChildrenCount（）被调用）。 我的问题是; 什么是需要的条件得到满足，才能有ExpandableListAdapter夸大它的孩子？

In my app, getChildView() inside my ExpandableListAdapter isn't being called while the adapter returns the correct child count (when getChildrenCount() is called). My question is; what are the conditions that need to be met, in order to have ExpandableListAdapter inflate its children?

推荐答案

被调用的时候，你在团体和孩子的有超过1项，我的意思是，当getGroupCount返回的值大于0

is called when you have more than 1 item in groups and in childs, i mean when getGroupCount returns a value greater than 0
