目标 ： 实现Tabbar也签的通用。
一 ： 美术资源的准备（自己做的 ， 很挫 ， 勿喷 ）如下
二 ： 通用页签ItemRenderer的皮肤 如下
三 ：tabbar的测试UI皮肤 如下
四 ：ItemRenderer的实现
module common{
/**
* 通用的页签CELL
* @author Husz
*/
export class common_TabBarCell extends eui.ItemRenderer{
private img_yes : eui.Image = null;
private img_no : eui.Image = null;
private img_txt : eui.Image = null;
public constructor(){
super();
this.skinName = "resource/common_skins/common_TabBarCell.exml";
}
protected createChildren():void{
super.createChildren();
}
protected dataChanged() : void{
let $dataModel : common_TabBarCell_Data = <common_TabBarCell_Data>this.data;
this.handlerBackGround( $dataModel );
this.handlerTxt( $dataModel );
}
/**
* 处理背景
* @param {common.common_TabBarCell_Data} $dataModel
*/
private handlerBackGround( $dataModel : common_TabBarCell_Data ) : void{
let $selected : boolean = $dataModel._selected;
this.img_yes.visible = $selected;
this.img_no.visible = !$selected;
}
/**
* 处理文本
* @param {common.common_TabBarCell_Data} $dataModel
*/
private handlerTxt( $dataModel : common_TabBarCell_Data ) : void{
let $textPathRes : string = "";
if($dataModel._selected == true){
$textPathRes = $dataModel._yes_txt_res;
}else{
$textPathRes = $dataModel._no_txt_res;
}
this.img_txt.source = RES.getRes($textPathRes);
}
/**
* 是否已经处于选择的状态（只读。。。。。。）
* @returns {boolean}
* @constructor
*/
public get IsSelected() : boolean{
let $dataModel : common_TabBarCell_Data = <common_TabBarCell_Data>this.data;
return $dataModel._selected;
}
}
/**
* 通用的页签CELL的数据模型
* @author Husz
*/
export interface common_TabBarCell_Data{
/**数据的下标*/
_index : number;
/**是否处于选择状态*/
_selected : boolean;
/**选择状态下的美术文本资源*/
_yes_txt_res : string;
/**未选择状态下的美术文本资源*/
_no_txt_res : string;
}
}五 ： TabBarDemoView UIDemo实现
