在Gui中對Button換皮相當的給力:

Gui.Button.skinName = new egret.gui.ButtonSkin(normal_resource, up_resource , disable_resource);

但是在EUI中沒有ButtonSkin類.所以找到了其他方法.

我用三種按鈕進行測試 : 1,有自定義皮膚的按鈕 2,沒有自定義皮膚的按鈕(三種狀態都有resource圖片) , 3,new的Button

測試View:

一 : 自定義皮膚情況

①,自定義皮膚 : AonauflyButton.exml

<?xml version="1.0" encoding="utf-8"?>
<e:Skin class="skins.AonauflyButton"  states="up,down,disabled" width="75" height="75" xmlns:e="http://ns.egret.com/eui">
    <e:Image width="100%" height="100%" scale9Grid="1,3,8,8" alpha.disabled="0.5"
             source="變強01_png"
             source.down="橙色小按鈕_png"
             source.disabled="藍色小按鈕_png"/>
    <e:Label id="labelDisplay" top="8" bottom="8" left="8" right="8"
             size="20"
             textColor="0xFFFFFF" verticalAlign="middle" textAlign="center"/>
    <e:Image id="iconDisplay" horizontalCenter="0" verticalCenter="0"/>
</e:Skin>

②,現在一個ButtonDemo.exml用於顯示如上圖.建一個Button,設置他的皮膚為我們的自定義皮膚

命名 : btn_demo

二 : 使用默認Button(三種狀態都有resource圖片)

命名 : btn_demo2

三 : 自定義一個Button , 命名 : $btn_demo3

代碼如下:

module app {
	export class ButtonDemo extends eui.Component implements eui.UIComponent {
		private btn_demo : eui.Button;
		private btn_demo2 : eui.Button;
		private $btn_demo3 : eui.Button;
		public constructor() {
			super();
			this.skinName = "resource/eui_skins/ButtonDemo.exml";
		}

		private handlerListener( isAdd : boolean ) : void{
			this.touchEnabled = isAdd;
			if( isAdd ){
				this.addEventListener( egret.TouchEvent.TOUCH_TAP , this.onclick , this );
			}else{
				this.removeEventListener( egret.TouchEvent.TOUCH_TAP , this.onclick , this );
			}
		}
		private onclick( $e : egret.TouchEvent ) : void{
			this.btn_demo.enabled = !this.btn_demo.enabled;
			this.btn_demo2.enabled = !this.btn_demo2.enabled;
			this.$btn_demo3.enabled = !this.$btn_demo3.enabled;
		}
		protected childrenCreated():void{
			super.childrenCreated();
			this.handlerListener(true);
			this.btn_demo.label="第一種情況";
			this.btn_demo.icon = RES.getRes("button_down_png");

			this.baseChildren4BTN(this.btn_demo);

			this.changeChildren4BTN( this.btn_demo );

			egret.log("===== 第二種情況 =====");

			this.baseChildren4BTN( this.btn_demo2 );
			this.changeChildren4BTN( this.btn_demo2 );

			egret.log("===== 第三種情況 =====");
			this.$btn_demo3 = new eui.Button();
			this.$btn_demo3.label = "第三種情況";
			this.$btn_demo3.x = this.$btn_demo3.y = 250;
			this.addChild( this.$btn_demo3 );

			this.baseChildren4BTN( this.$btn_demo3 );
			this.changeChildren4BTN( this.$btn_demo3 );

		}

		private baseChildren4BTN(btn : eui.Button) : void{
			let $img2Btn_normal : eui.Image = <eui.Image>btn.getChildAt(0);
			egret.log(" 常態 img 0 :" + $img2Btn_normal.source);
			// 改變常態img( 成功 )
			// $img2Btn_normal.source = RES.getRes("藍色小按鈕_png");

			let $label2Btn : eui.Label = <eui.Label>btn.getChildAt(1);
			egret.log(" 文本 1 :" + $label2Btn.text);
			if( btn.numChildren >= 3 ){
				let $icon2Btn : eui.Image = <eui.Image>btn.getChildAt(2);
				if( $icon2Btn != null && $icon2Btn.source != null)
					egret.log("icon 2 :" + $icon2Btn.source.toString());
			}
		}

		private changeChildren4BTN(btn : eui.Button) : void{
			if( btn.skin != null && btn.skin.states != null){
				let arr2States : eui.State[] = btn.skin.states;
				let target2State : eui.State = null;
				//up - 狀態
				target2State = arr2States[1];
				let property2up: eui.SetProperty = <eui.SetProperty>target2State.overrides[ target2State.overrides.length -1];
				if( property2up.name == "source" ){
					egret.log("up : value ->" + property2up.value );
					property2up.value = RES.getRes("藍色小按鈕_png");
				}
				//disabled 狀態
				target2State = arr2States[2];
				let property2d: eui.SetProperty = <eui.SetProperty>target2State.overrides[ target2State.overrides.length -1];
				if( property2d.name == "source" ){
					egret.log("--改變圖片資源--");
					egret.log("disabled : value ->" + property2d.value );
					property2d.value = RES.getRes("radiobutton_select_up_png");
				}else if( property2d.name == "alpha" ){
					egret.log("--改變圖片透明度--");
					property2d.value = 0.3;//改變透明度
				}

			}

		}
	}
}

要更改normal :

要更改 up , disable :(可以同時有alpha和source , 可以同時得修改他們)
