关于请求下数据后，怎么在ExpandableListView上展示

是弄成集合还是数组，适配器里面怎么弄，弄成集合的话。
思路乱的不行啊。

public class ExpandableAdapter extends BaseExpandableListAdapter{

     private LinkedList<TeacherSumGroupsModel> groupArray;
     private List<LinkedList<TeacherSumGroupDetailModel>> childArray;
     private Context context;
     private LayoutInflater inflater;


     public ExpandableAdapter(Context context,LinkedList<TeacherSumGroupsModel> courseGroupList,
                List<LinkedList<TeacherSumGroupDetailModel>> childArray){
         inflater = ((Activity) context).getLayoutInflater();

         this.groupArray = courseGroupList;
         this.childArray = childArray;
     }



    public int getGroupCount() {
        // TODO Auto-generated method stub
        return groupArray.size();
    }

    public int getChildrenCount(int groupPosition) {
        // TODO Auto-generated method stub
        return childArray.get(groupPosition).size();
    }

    public Object getGroup(int groupPosition) {
        // TODO Auto-generated method stub
        return groupArray.get(groupPosition);
    }

    public Object getChild(int groupPosition, int childPosition) {
        // TODO Auto-generated method stub
        return childArray.get(groupPosition).get(childPosition);
    }

    public long getGroupId(int groupPosition) {
        // TODO Auto-generated method stub
        return groupPosition;
    }

    public long getChildId(int groupPosition, int childPosition) {
        // TODO Auto-generated method stub
        return childPosition;
    }

    public boolean hasStableIds() {
        // TODO Auto-generated method stub
        return false;
    }

    public View getGroupView(int groupPosition, boolean isExpanded,
            View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        TextView title;

        if(convertView == null){
            convertView = inflater.inflate(R.layout.simple_listview_item, parent, false);
        }
        title = (TextView) convertView.findViewById(R.id.simple_listview_textview);
        String t = "     "+groupArray.get(groupPosition).getname();
        title.setText(t);
        return convertView;
    }

    public View getChildView(int groupPosition, int childPosition,
            boolean isLastChild, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        TextView title;

        if(convertView == null){
            convertView = inflater.inflate(R.layout.simple_listview_item, parent, false);
        }
        title = (TextView) convertView.findViewById(R.id.simple_listview_textview);

        String account = childArray.get(groupPosition).get(childPosition).getAccount();
        String name = childArray.get(groupPosition).get(childPosition).getName();
        String t = account +"          "+name;
        Log.e("sumlist", "info is " +t);
        title.setText(t);
        return convertView;
    }

    public boolean isChildSelectable(int groupPosition, int childPosition) {
        // TODO Auto-generated method stub
        return true;
    }

}

XML定义好ExpandableListView之后
首先你要自定义好你自己的视图适配器继承自BaseExpandableListAdapter
然后重写里面的方法：
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView,
ViewGroup parent) {

    final Object obj = getChild(groupPosition, childPosition);
    // 处理，你可以绑定多个数据源的，
    }
