两个list之间的拖动，代码如下：

<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="creationHandler();"> <mx:Script>  <![CDATA[   import mx.events.DragEvent;   import mx.collections.ArrayCollection;   [Bindable]   public var isEnabled:Boolean = true;   private static const DIS_LABEL:String = "不能拖拽";   private static const EN_LABEL:String = "可以拖拽";    private function creationHandler():void {    list1.dataProvider = new ArrayCollection(['Spider Monkey', 'Orangutan', 'Gorilla']);    list2.dataProvider = new ArrayCollection(['Lion', 'Cheetah', 'Puma'])   }   private function clickHandler():void {    enableBtn.label = ( enableBtn.label == DIS_LABEL ) ? EN_LABEL : DIS_LABEL;    isEnabled = !isEnabled;   }   private function dragEnterHandler( evt:DragEvent ):void {    evt.target.dropEnabled = ( evt.target != evt.dragInitiator );   }  ]]> </mx:Script> <mx:VBox width="100%" height="100%">  <mx:Button id="enableBtn" label="{EN_LABEL}" click="clickHandler();"/>  <mx:HBox width="100%" height="100%">   <mx:List  id="list1" width="200" height="200" dragEnabled="{isEnabled}" dragMoveEnabled="true" dragEnter="dragEnterHandler(event);"/>   <mx:List id="list2" width="200" height="200" dragEnabled="{isEnabled}" dragMoveEnabled="true" dragEnter="dragEnterHandler(event);"/>  </mx:HBox> </mx:VBox></mx:Application>
