视图状态切换：
<?xml version="1.0" ?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
backgroundColor="#FFFFFF">
<mx:states>
    <mx:State name="Description">
      <mx:AddChild relativeTo="{hbox1}" position="before">
        <mx:TextArea width="200" height="180"
        borderStyle="none"
        text="Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. "/>
      </mx:AddChild>
      <mx:RemoveChild target="{descButton}"/>
      <mx:AddChild relativeTo="{hbox1}" position="before">
        <mx:Button label="Close Description"
        click="this.currentState=''"/>
      </mx:AddChild>
    </mx:State>
</mx:states>
<mx:VBox id="vbox1" borderStyle="outset" paddingLeft="5" paddingBottom="5" paddingRight="5" paddingTop="5">
    <mx:Label text="Product Name" fontWeight="bold" />
    <mx:Button label="Open Description"
   click="this.currentState='Description'"
   id="descButton"/>
    <mx:HBox id="hbox1">
      <mx:Label text="$3.99"/>
      <mx:NumericStepper id="qty" minimum="1"
       maximum="10" stepSize="1"/>
    <mx:Button label="Add to Cart"/>
    </mx:HBox>
</mx:VBox>
</mx:Application>
使用过渡：由于状态切换过于突然，要变的温和一些
