Как добавить многоуровневый расширяемый список?(Android)

Question

У меня есть одноуровневый Expandablelistview в Android, и он отлично работает. Как я могу добавить многоуровневый расширяемый просмотр списка, используя LinkedHashMap Пожалуйста, помогите мне решить, используя LinkedHashMap, который содержит данные

 ExpandableListAdapterParent listAdapter;
    ExpandableListView expListView;
 List<String> listDataHeader;
 LinkedHashMap<String, List<String>> listDataChild;
  listDataHeader = new ArrayList<String>();
    listDataChild = new LinkedHashMap<String, List<String>>();
    // Adding Parent data
    listDataHeader.add("l1");
    listDataHeader.add("l2");
    listDataHeader.add("l3");
    listDataHeader.add("l4");
    listDataHeader.add("l5");
    listDataHeader.add("l6");
    // Adding child data
    List<String> l1= new ArrayList<String>();
    l1.add("item1");
    l1.add("item1");
    l1.add("item1");
    l1.add("item1");
    List<String> l2= new ArrayList<String>();
    l2.add("item2");
    l2.add("item2");
    l2.add("item2");
    l2.add("item2");
    listDataChild.put(listDataHeader.get(0), l1); // Header, Child data
    listDataChild.put(listDataHeader.get(1), l2);
    listDataChild.put(listDataHeader.get(2), l3);
    expListView = (ExpandableListView) findViewById(R.id.lvExp);
     listAdapter = new ExpandableListAdapterParent(this, listDataHeader, 
 listDataChild);
    // setting list adapter
    expListView.setAdapter(listAdapter);

ExpandableListView Адаптер родительского класса приведен ниже, я накачал макет одним объектом textview

public class ExpandableListAdapterParent extends BaseExpandableListAdapter {

private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<String>> _listDataChild;

public ExpandableListAdapterParent(Context context, List<String> listDataHeader,
                                   HashMap<String, List<String>> listChildData) {
    this._context = context;
    this._listDataHeader = listDataHeader;
    this._listDataChild = listChildData;
}

@Override
public Object getChild(int groupPosition, int childPosititon) {
    return this._listDataChild.get(this._listDataHeader.get(groupPosition))
            .get(childPosititon);
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

@Override
public View getChildView(int groupPosition, final int childPosition,
                         boolean isLastChild, View convertView, ViewGroup parent) {

    final String childText = (String) getChild(groupPosition, childPosition);

    if (convertView == null) {
        LayoutInflater infalInflater = (LayoutInflater) this._context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_item, null);
    }

    TextView txtListChild = (TextView) convertView
            .findViewById(R.id.lblListItem);

    txtListChild.setText(childText);
    return convertView;
}

@Override
public int getChildrenCount(int groupPosition) {
    return this._listDataChild.get(this._listDataHeader.get(groupPosition))
            .size();
}

@Override
public Object getGroup(int groupPosition) {
    return this._listDataHeader.get(groupPosition);
}

@Override
public int getGroupCount() {
    return this._listDataHeader.size();
}

@Override
public long getGroupId(int groupPosition) {
    return groupPosition;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
                         View convertView, ViewGroup parent) {
    String headerTitle = (String) getGroup(groupPosition);
    if (convertView == null) {
        LayoutInflater infalInflater = (LayoutInflater) this._context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = infalInflater.inflate(R.layout.list_group, null);
    }

    TextView lblListHeader = (TextView) convertView
            .findViewById(R.id.lblListHeader);
    lblListHeader.setTypeface(null, Typeface.BOLD);
    lblListHeader.setText(headerTitle);

    return convertView;
}

@Override
public boolean hasStableIds() {
    return false;
}

@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

}
