egret editor list更换内容

this.ArrayCollection_arr=new eui.ArrayCollection();

this.ArrayCollection_arr.source=this.icon_list_arr;
this.icon_list.itemRenderer = Firstlistbtn;
this.icon_list.dataProvider =this.ArrayCollection_arr;
this.icon_list.addEventListener(eui.ItemTapEvent.ITEM_TAP,this.icon_list_handle,this);
this.list_scroller.addEventListener(egret.Event.ENTER_FRAME, this.onCheckJumpEvent, this);

划重点：

此方法会更新位置

this.ArrayCollection_arr.source=this.icon_list_arr;

此方法不会更新位置

this.ArrayCollection_arr.replaceAll(this.icon_list_arr);
