如何使用相同的List <object>填充expandablelistview的父级和子级

Question

我有一个对象列表，我想用这些对象的数据填充ExpandableListView。我想在ExpandableListView的父级中显示对象的一个​​属性，并在ExpandableListView的子级中显示对象的另一个属性。任何人都可以告诉我我该怎么做，我的代码就像这些;

当我使用这些代码时，只有一个父行显示在ExpandableList上，bu列表有多个对象。

public class textExpAdapter extends BaseExpandableListAdapter {

public List<textexplain> tmpTextExp;
public Context context;
public LayoutInflater inflater;

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

public textExpAdapter (Context context, List<textexplain> tmpTextExp)
{
    this.context = context;
    this.tmpTextExp= tmpTextExp;
}

@Override
public int getChildrenCount(int groupPosition) {

    return 1;
}

@Override
public Object getGroup(int groupPosition) {

    return tmpTextExp.get(groupPosition);
}

@Override
public Object getChild(int groupPosition, int childPosition) {

    return tmpTextExp.get(childPosition);

}

@Override
public long getGroupId(int groupPosition) {

    return groupPosition;
}

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

    return childPosition;
}

@Override
public boolean hasStableIds() {

    return false;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded,
                         View view, ViewGroup parent) {

    textexplain action = (textexplain) getGroup(groupPosition);

    if(view == null)
    {
        inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.crmactions_elv_head,null);
    }

    final TextView txtCrmActionHeaderClm1 = (TextView)view.findViewById(R.id.txtCrmActionHeaderClm1);
    final TextView txtCrmActionHeaderClm2 = (TextView)view.findViewById(R.id.txtCrmActionHeaderClm2);

    SimpleDateFormat sdFormat = new SimpleDateFormat("dd.MM.yyyy");

    txtCrmActionHeaderClm1.setText(sdFormat.format(action.ACTIONDATE));
    txtCrmActionHeaderClm2.setText(action.STEXT);

    return view;
}

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

    textexplain action = (textexplain) tmpTextExp.get(groupPosition);
    if(view==null)
    {
        inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        view = inflater.inflate(R.layout.crmactions_elv_bottom, null);
    }

    final TextView txtCrmActionBottomText = (TextView)view.findViewById(R.id.txtCrmActionBottomText);
    txtCrmActionBottomText.setText(action.LTEXT);
    return view;
}

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

}
