自定義了一個expandablelistview 想要刪除其中的子項

list使用remove方法把list中的指定項刪除了

11-09 21:04:20.585: I/MainActivity(13557): childData=[{child_text=second}, {child_text=third}]

但是在expandablelistview界面顯示中，并沒有變化,并且還有list溢出報錯

定義部分

private ExpandableListView expandablelistview;

private MyAdapter expandableAdapter;

private String [] groupStr={"第一組","第二組","第三組"};

private String [] childStr={"first","second","third"};

private List> groupData = new ArrayList>();

private List> childData = new ArrayList>();

initData()方法如下：

for(int i=0;i<3;i++){

//給標題賦值

Map curGroupMap=new HashMap();

curGroupMap.put("group_title", groupStr[i]);

groupData.add(curGroupMap);

//給子項賦值

Map curChildMap=new HashMap();

curChildMap.put("child_text", childStr[i]);

childData.add(curChildMap);

}

適配器代碼如下：

class MyAdapter extends BaseExpandableListAdapter{

@Override

public Object getChild(int arg0, int arg1) {

// TODO Auto-generated method stub

return childData.get(arg0);

}

@Override

public long getChildId(int arg0, int arg1) {

// TODO Auto-generated method stub

return arg1;

}

@Override

public View getChildView(int arg0, int arg1, boolean arg2, View arg3,

ViewGroup arg4) {

// TODO Auto-generated method stub

if(arg3==null){

LayoutInflater inflater=(LayoutInflater)Main.

this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

arg3=inflater.inflate(R.layout.child,null);

}

TextView textview=(TextView)arg3.findViewById(R.id.childtext);

textview.setText(childStr[arg0]);

return arg3;

}

@Override

public int getChildrenCount(int arg0) {

// TODO Auto-generated method stub

return childData.get(arg0).size();

}

@Override

public Object getGroup(int arg0) {

// TODO Auto-generated method stub

return groupData.get(arg0);

}

@Override

public int getGroupCount() {

// TODO Auto-generated method stub

return groupData.size();

}

@Override

public long getGroupId(int arg0) {

// TODO Auto-generated method stub

return arg0;

}

@Override

public View getGroupView(int arg0, boolean arg1, View arg2,

ViewGroup arg3) {

// TODO Auto-generated method stub

if(arg2==null){

LayoutInflater inflater=(LayoutInflater)Main.

this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

arg2=inflater.inflate(R.layout.group, null);

}

TextView textview=(TextView)arg2.findViewById(R.id.grouptext);

textview.setText(groupStr[arg0]);

return arg2;

}

@Override

public boolean hasStableIds() {

// TODO Auto-generated method stub

return true;

}

@Override

public boolean isChildSelectable(int arg0, int arg1) {

// TODO Auto-generated method stub

return true;

}

}
