我正在添加三个名为All Homes所有图和All Commercial的子对象，我在运行时添加这三个对象，其中三个父项是Homes Plots和Commercial，所以在其他方面我要添加另外三个类别在我的父母作为child.i做了它，因为每当我加载我的expandableListview它加载我的数组的0索引上的子，但每当我尝试点击这些新创建的对象时，我得到indexoutofboundexception错误方法getChildView（）因为IndexOutOfBoundException无效索引7大小为7，当我单击子数据时，调试器显示此错误，当我回到它时，它会在此方法中显示此indexoutofBoundException错误。我遇到错误的方法是
rbSelect.setText(Utils.propertyTypesList.get(groupPosition).getChildList().get(childPosition).getTitle());
我的代码是。
