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。 我的修改后的代码
private void displayListListView(){
final ExpandableListView listview = (ExpandableListView)mView. findViewById(R.id.expandableListView);
final ExpendableAdapter expendableAdapter = new ExpendableAdapter();
//ArrayList<PropertyParent> childs = new ArrayList<PropertyParent>();
//PropertyParent parent = new PropertyTypeInfo().new PropertyParent();
PropertyTypeInfo property = new PropertyTypeInfo();
for(int i=0;i<Utils.propertyTypesList.size();i++)
{
// if( Utils.propertyTypesList.size()>0)
//{
property = Utils.propertyTypesList.get(i);
//if(property.getParentId()=="1" && property!=null){
if(parent==null)
{
parent = new PropertyTypeInfo().new PropertyParent();
parent.setTypeId("9,8,21,22,20,24,25");
parent.setTitle(value.concat(property.getTitle()));
parent.setTitleAlt2("All Houses");
parent.setParentId("1");
parent.setTitleAlt1("All House");
childs= property.getChilds();
childs.add(0, parent);
}
//}
else if(parent.getTypeId()=="9,8,21,22,20,24,25"){
parent = new PropertyTypeInfo().new PropertyParent();
parent.setTypeId("12,23,11,19,26,27");
parent.setTitle(value.concat(property.getTitle()));
parent.setTitleAlt2("All Plots");
parent.setParentId("2");
parent.setTitleAlt1("Residential Plot");
childs= property.getChilds();
childs.add(0, parent);
}
else if(parent.getTypeId()== "12,23,11,19,26,27")
{
parent = new PropertyTypeInfo().new PropertyParent();
parent.setTypeId("13,15,17,14,16,18");
parent.setTitle(value.concat(property.getTitle()));
parent.setTitleAlt2("All Commercial");
parent.setParentId("3");
parent.setTitleAlt1("Commercial");
childs= property.getChilds();
childs.add(0,parent);
}
//else
//{
//}
}
// }
expendableAdapter.notifyDataSetChanged();
listview.setAdapter(expendableAdapter);
//expendableAdapter.notifyDataSetChanged();
listview.setOnChildClickListener(new OnChildClickListener() {
，我的getChildView方法
@Override
public View getChildView(int groupPosition, int childPosition,boolean isLastChild, View convertView, ViewGroup parent) {
if(convertView == null){
convertView = inflater.inflate(R.layout.radio_item, parent, false);
}
RadioButton rbSelect = (RadioButton) convertView
.findViewById(R.id.radioButton1);
rbSelect.setText(Utils.propertyTypesList.get(groupPosition).getChildList().get(childPosition).getTitle());
if(selectedIndexChild == childPosition && selectedIndexParent == groupPosition){
rbSelect.setChecked(true);
}
else{
rbSelect.setChecked(false);
}
return convertView;
}
}

答案 0 :(得分：0)
请更改循环大小
你必须循环条件看起来像这样..
for（int i = 0; i＆lt; Utils.propertyTypesList.size（） - 1; i ++）
尺寸-1
