        public function getMenuDataIndex(data:*):int
        {
            for(var i:int=0;i

使用示例

UICellGroup.initList(m_list,TacticalCell,true,null,Handler.create(this, onListSelect,null,false));
m_list.dataSource=m_arrSkillCellData;  
UICellGroup.AutoSelectList(m_list,_selectListIndex);
private function onListSelect(e:Event,index:int):void{
       if(e.type==Event.CLICK){               
        //修改列表项选中状态（cell中可以通过select变量判断是否被选中）    
          UICellGroup.onListSelect(m_list,m_arrSkillCellData,index);
       }
}

配套cellData，列表项继承该类

{
    //通用CellData结构，可满足大部分UICell应用
    //如果参数不足，可以继续添加arg1,arg2;
    public class UICellData
