[解决办法]
这样子写：

Java code

<?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">    <s:layout>        <s:VerticalLayout paddingLeft="40" paddingTop="40"/>    </s:layout>    <fx:Script>        <![CDATA[            import mx.controls.Alert;            import mx.events.ValidationResultEvent;                        protected function button1_clickHandler(event:MouseEvent):void            {                // TODO Auto-generated method stub                if (stringValidator1.validate().type == ValidationResultEvent.VALID ||                stringValidator2.validate().type == ValidationResultEvent.VALID)                    Alert.show("两者必须填写一个的情况成功发生。", "演示");            }        ]]>    </fx:Script>    <fx:Declarations>        <!-- Place non-visual elements (e.g., services, value objects) here -->        <mx:StringValidator id="stringValidator1" source="{this.textInput1}" property="text" required="true"/>        <mx:StringValidator id="stringValidator2" source="{this.textInput2}" property="text" required="true"/>    </fx:Declarations>    <s:TextInput id="textInput1" />    <s:TextInput id="textInput2" />    <s:Button label="演示" click="button1_clickHandler(event)"/></s:Application>
