IndexOutofBoundException getChildView（）in expandableListView
问题描述：
我添加了三个子对象，名称为All Homes所有地块和所有商业地产，我在运行时做这些事情时，我将这三个对象与三个父母一起添加到Home Plots和Commercial中，条款我在我的父母添加三个类别作为child.i已完成与它每当我加载我的expandableListview它加载子数组的索引我的数组，但每当我尝试点击这些新创建的对象我得到indexoutofboundexception错误方法getChildView（）作为IndexOutOfBoundException无效索引7大小是7和调试器显示此错误，当我点击子数据填充，当我导航回它显示此indexoutofBoundException在此方法的错误。 我修改的代码是IndexOutofBoundException getChildView（）in expandableListView
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() {
和我getChildView方法是
@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;
}
}
我的JSON数据是

答
请改变你的循环大小
你要循环的情况看是这样..
的for（int i = 0;我< Utils.propertyTypesList.size（） - 1;我++）
大小-1
+0
如果我使它Utils.propertyTypesList.size（） - 1那么数组会没有正确的遍历它会去0和1索引，并会离开2索引，因此只有所有家庭的所有情节将显示，但错误仍然存在，当填充数据时点击单选按钮，我来bak indexoutofbound异常错误来和应用程序崩溃 –
旁注：parent.getTypeId（）==“9,8,21,22,20,24,25”。将==替换为.equals。另外，为什么你将父项添加到你的childList？ – Carnal
@carnal在我工作的时候，他们已经从基于web服务的url中获取数据，但是现在他们想要硬编码三个类别All Homes，All Plots，All Commercial，以便All Homes所有家庭孩子都来了，如果他们想要添加另一个功能，他们可以在不改变其API的情况下对其进行硬编码以获得结果，那么在将来和未来都会如此。 –
它又来java.lang.IndexOutOfBoundsException：无效索引7，大小为7 \t at fragments.Types $ ExpendableAdapter.getChildView（Types.java:254） –
