【问题描述】：
我要添加三个子对象，名称为 All Homes All plots 和 All Commercial在我的父母中作为孩子。我已经完成了它，因为每当我加载我的 expandableListview 时，它会将孩子加载到我的数组的 0 索引上，但是每当我尝试点击这些新创建的对象时，我在方法 getChildView() 处得到 indexoutofboundexception 错误，因为 IndexOutOfBoundException 无效索引 7 的大小为 7，当我单击子数据填充时调试器显示此错误，当我导航返回时，它在此方法中显示此 indexoutofBoundException 错误。 我修改后的代码是
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() {
而我的 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;
}
}
我在 Json 中的数据是

【问题讨论】：
-
旁注：parent.getTypeId()=="9,8,21,22,20,24,25"。将 == 替换为 .equals。另外，为什么要在 childList 中添加父级？
-
@carnal 我在哪里工作，他们已经根据网络服务从 url 获取数据，但现在他们想硬编码三个类别 All home、All Plots、All Commercial，以便在所有家庭中所有家庭孩子的come and in All Plots plots child come and in future if they want to add another function they can hard code it to get results without change in their API.

又来了 java.lang.IndexOutOfBoundsException: Invalid index 7, size is 7 at Fragments.Types$ExpendableAdapter.getChildView(Types.java:254)
