Flex4中的List组件的使用,具体代码如下:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
			   xmlns:s="library://ns.adobe.com/flex/spark" creationComplete="application1_creationCompleteHandler(event)" 
			   xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
	<s:layout>
		<s:BasicLayout/>
	</s:layout>
	<fx:Script>
		<![CDATA[
			import mx.collections.ArrayCollection;
			import mx.events.FlexEvent;
			
			[Bindable]
			private var listData:ArrayCollection = null;
			protected function application1_creationCompleteHandler(event:FlexEvent):void
			{
				// TODO Auto-generated method stub
				listData = new ArrayCollection([
					{label:"请选择"},
					{label:"语文"},
					{label:"数学"},
					{label:"英语"}
				]);
			}

		]]>
	</fx:Script>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	<!--定义List列表-->
	<s:List id="sid" y="200" x="400" dataProvider="{listData}" selectedIndex="0"/>
	
</s:Application>
