flex ArrayCollection的排序其实是比较简单的,只要利用它的sort属性就可以了,下面是具体的代码,是按钮降序排列的,如果要按升序,改变相应的参数就可以了.

   private     dgData:ArrayCollection = new ArrayCollection();
 
//在arrayCollection里面添加些数据
 
  dgData.addItem(
     {ID:0,userName:'AAA'},
     {ID:1,userName:'CCC'},
     {ID:2,userName:'BBB'}
);
 
//进行排序
 
     var sort:Sort = new Sort();
 
//按某一个字段进行查询
      sort.fields = [new SortField("ID",true,true)];
      dgData.sort = sort;
      dgData.refresh();

注:默认是按照升序排序的,不用带相关参数
sort.fields = [new SortField(“userName”)];
