ExpandableListView SimpleExpandableListAdapter 添加数据报错

[jinxuxin2009]

如题 代码如下

m_GroupData = new ArrayList<Map<String, Object>>();
m_ChildData = new ArrayList< List<Map<String, Object>>>();
m_GroupFriends = new ArrayList<List<Friend>>();
Map<String, Object> TmpGroupItem = new HashMap<String, Object>();
TmpGroupItem.put(GROUPNAME, "GroupName");
TmpGroupItem.put(GROUPSIGN, "GroupSign");
TmpGroupItem.put(GROUPHEAD, 2);
TmpGroupItem.put(NUM, "12");

m_GroupData.add(TmpGroupItem);

List<Map<String, Object>> TmpChildGroup = new ArrayList<Map<String, Object>>();

Map<String, Object> TmpChildItem = new HashMap<String, Object>();

TmpChildItem.put(NAME, "childname");
TmpChildItem.put(SIGN, "childsign");
TmpChildItem.put(HEAD, 3);
TmpChildItem.put(SCORE, "childscore");
TmpChildItem.put(TIMES, "12");

TmpChildGroup.add(TmpChildItem);

m_ChildData.add(TmpChildGroup);
m_Adapter = new SimpleExpandableListAdapter(context, m_GroupData, R.layout.groupitem,
new String[]{GROUPNAME, GROUPSIGN, GROUPHEAD, NUM},
new int[]{R.id.GroupName, R.id.GroupSiged, R.id.GroupImg, R.id.Num},
m_ChildData, R.layout.friends,
new String[]{NAME, SIGN, HEAD, SCORE, TIMES},
new int[]{R.id.Name, R.id.Siged, R.id.HeadImg, R.id.Score, R.id.SuccessTime});

this.setAdapter(m_Adapter);

XML文件里都没看到ExpandableListView的定义,代码里也没看到初始化
