egret 的scroll使用方法

这是我的e 文件结构，然后把e 加载进去.

先初始化，给控件list设置属性和数据

this.sourceArr = new Array();

for (var i:number = 0; i < 40; i++){

//给数据中添加一个含有\"label\"属性的对象

this.sourceArr.push({label:i});

}

this.arrCollection = new eui.ArrayCollection(this.sourceArr);

this.List_users.dataProvider = this.arrCollection;

this.List_users.itemRenderer = LabelRenderer;

export class LabelRenderer extends eui.ItemRenderer {

private Group_otherdi:eui.Group;

private Image_otherdi:eui.Image;

private label_name:eui.Label;

private head_bg:eui.Image;

private user_head:eui.Image;//头像

private user_name:eui.Label;//名字

private user_money:eui.Label;//金钱

private Image_jinbi:eui.Image;//金币

public constructor(){

super();

this.touchChildren = true;

this.Group_otherdi = new eui.Group();

this.Group_otherdi.width = 300;

this.Group_otherdi.height = 90;

this.addChild( this.Group_otherdi );

this.Group_otherdi.touchEnabled = false;

this.label_name = new eui.Label();

this.Group_otherdi.addChild( this.label_name );

this.label_name.top = 10;

this.label_name.left = 10;

//this.label_name.text = \"李逵\"

this.user_head = new eui.Image();

this.Group_otherdi.addChild( this.user_head );

this.user_head.source = \"BJL_head_10_png\"

this.user_head.scaleX = 0.5;

this.user_head.scaleY = 0.5;

this.user_head.x = 20

this.user_name = new eui.Label();

this.user_name.text = \"科比.布莱恩特\";

this.addChild(this.user_name);

this.user_name.x = 120;

this.user_name.y = 15;

this.user_name.size = 20;

this.Image_jinbi = new eui.Image();

this.addChild(this.Image_jinbi);

this.Image_jinbi.source = \"BJL_jinbi\";

this.Image_jinbi.x = 120;

this.Image_jinbi.y = 40;

this.user_money = new eui.Label();

this.user_money.text = \"10000\";

this.addChild(this.user_money);

this.user_money.x = 120+35;

this.user_money.y = 50;

this.user_money.textColor = 0xFCE358;

this.user_money.size = 20;

}

protected dataChanged():void{

//显示数据中的 label 值

this.label_name.text = this.data.label;

}

}

}

这样在LabelRenderer类中的dataChanged函数中改变你想要的。

最后运行结果是这样的：

如果要刷新的话怎么办，重新设置数据刷新就可以了：

public updateUserList(){
            this.sourceArr = new Array();
            for (var i:number = 1; i < 10; i++){
                //给数据中添加一个含有\"label\"属性的对象
                this.sourceArr.push({label:i});
            }
            this.arrCollection.source = this.sourceArr;
            this.arrCollection.refresh();
        }
