2.自定义的事件类，传递点击表格的内容

package events {
	import flash.events.Event;
	
	public class ListClickEvent extends Event {
		public var lablepinyi:String;
		public var lablename:String;

		public function ListClickEvent(type:String, lablepinyi:String,lablename:String ) {
			super(type, true);
			this.lablepinyi = lablepinyi;
			this.lablename = lablename;
		}
		
		override public function clone():Event {
			return new ListClickEvent( type, lablepinyi,lablename );
		}
	}
}

3.自定义的List类：

package components.List
{
	import spark.components.List;
	
	[Event(name="listItemClick",type="events.ListClickEvent")]
	public class MyList extends List
	{
		public function MyList()
		{
			super();
		}
	}
}

4.自定义的list呈示器：

<?xml version="1.0" encoding="utf-8"?>
<s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009" 
				xmlns:s="library://ns.adobe.com/flex/spark" 
				xmlns:mx="library://ns.adobe.com/flex/mx" 
				autoDrawBackground="true">
	<fx:Metadata>
		[Event(name="listItemClick",type="events.ListClickEvent")]
	</fx:Metadata>
	<fx:Script>
		<![CDATA[
			import events.ListClickEvent;
			
			import mx.controls.Alert;
			
			protected function getColor(data:Object):uint
			{
				var lindex:int= Number(data.number.toString());
				if(lindex%2==0){
					return 0xf5f6f6;
				}else{
					return 0xffffff;
				}
			}
			
			
			protected function getColorRect(data:Object):uint
			{
				var level:String= data.level.toString();
				if(level=="无风险"){
					return 0x008aff;
				}else if(level=="低风险"){
					return 0xfdd868;
				}else if(level=="中风险"){
					return 0xff861a;
				}else if(level=="高风险"){
					return 0xff001e;
				}else {
					return 0x008aff;
				}
			}
			

			protected function bordercontainer1_clickHandler(event:MouseEvent):void
			{
				var listclickevent:ListClickEvent=new ListClickEvent("listItemClick",data.pingyin,data.drainagebasin);
				dispatchEvent(listclickevent);
			}

		]]>
	</fx:Script>
	<s:BorderContainer  width="528" borderVisible="false" click="bordercontainer1_clickHandler(event)">
		<s:Rect id="backgroundRect" left="0" right="0" top="0" bottom="0">
			<s:fill>
				<s:SolidColor color="0xdbdbdb" />
			</s:fill>
		</s:Rect>
		<s:Rect left="1" right="1" top="0" bottom="1">
			<s:fill>
				<s:SolidColor  color="{getColor(data)}"/>
			</s:fill>
		</s:Rect>
		<s:HGroup height="33" verticalAlign="middle" paddingLeft="40" gap="0">
			<s:Label text="{data.number}" color="0x666666" width="80"/>
			<s:Label text="{data.drainagebasin}" color="0x666666" width="100"/>
			<s:Label text="{data.hour}" color="0x666666" width="100"/>
			<s:Label text="{data.arealRainfall}" color="0x666666" width="100"/>
			<s:Rect  left="0" right="0" top="0" bottom="0"  width="10" height="10" >
				<s:stroke>
					<s:SolidColorStroke color="0xb9b9b9" weight="1"/>
				</s:stroke>
				<s:fill>
					<s:SolidColor color="{getColorRect(data)}"/>
				</s:fill>
			</s:Rect>
			<s:Label  paddingLeft="5" text="{data.level}" color="0x666666" width="95"/>
		</s:HGroup>
	</s:BorderContainer>
</s:ItemRenderer>
