开始把控件局限在label上，发现实现起来似乎不太现实。应该用textarea控件：

复制代码 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”
xmlns:mx=”library://ns.adobe.com/flex/mx” minWidth=”955″ minHeight=”600″ creationComplete=”inital();”>
<fx:Script>
<![CDATA[
import flashx.textLayout.conversion.TextConverter;
public function inital():void{
var str:String = “<font color=’#ff0000′>123456<font color=’#32CD32′>shit</font></font>”;
txt.textFlow = TextConverter.importToFlow(str, TextConverter.TEXT_FIELD_HTML_FORMAT);
//txtArea.text = “我是中国人我是中国人我是中国人我是中国人”;
}
]]>
</fx:Script>
<mx:Canvas x=”300″ y=”300″>
<s:TextArea>
</s:TextArea>
</mx:Canvas>
</s:Application>
