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>
