Question

急需Flex的答案，无法将“<mx:Array>”解析为组件执行

<?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"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

<fx:Declarations>
<!-- 将非可视元素（例如服务、值对象）放在此处 -->
</fx:Declarations>

<s:Label x="100" y="100" text="这是第一个Flex程序" fontFamily="Verdana" fontSize="21" color="#000000" verticalAlign="middle" fontWeight="bold"/>
<s:TextInput x="100" y="200" text="这是第一个Flex程序" fontFamily="Verdana" fontSize="21" fontWeight="bold" textAlign="center"/>
<s:List x="472" y="94" width="244" height="52" dataProvider="roomList"></s:List>

<mx:Array id="roomList">
<mx:String>room1</mx:String>
<mx:String>room2</mx:String>
<mx:String>room3</mx:String>
<mx:String>room4</mx:String>
</mx:Array>

</s:Application>
第11行代码 <mx:Array id="roomList">提示 无法将“<mx:Array>”解析为组件执行，这是什么原因啊

Answer 1

改成：
<fx:Declarations>
<fx:Array id="roomList">
<fx:String>room1</fx:String>
<fx:String>room2</fx:String>
<fx:String>room3</fx:String>
<fx:String>room4</fx:String>
</fx:Array>
</fx:Declarations>

Answer 2

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
我不太懂哦？

var roomList:Array = new Array("room1", "room2", "room3","room4");

Answer 3

flex 4 里面 Array 的前缀是 fx，应该写成 <fx:Array />
