     var list : List = new List(); 
     list.setSize(361, 291); 
     list.move(421, 254); 
     var i : uint; 
     for (i = 1; i < 8; i++) { 
      list.addItem({label:"Track " + i}); 
     } 
     list.addItem({label:"Track 1"}); 
     list.addItem({label:"Track 2"});

    public function itemClick() { 
     status_txt.text = "You selected: " + event.target.selectedItem.label; 
    } 
}

尝试总是做容易，你不需要butdin类，你可以直接在插入您的列表舞台，然后创建您的项目的文档类：

package { 

    import flash.display.MovieClip; 
    import flash.events.MouseEvent; 
    import flash.events.Event; 

    public class Main extends MovieClip { 

     public function Main() { 
      butdin.addEventListener(MouseEvent.CLICK, btn_on_Press); 
      list.addEventListener(Event.CHANGE, list_on_Change); 
     } 
     private function btn_on_Press(e:MouseEvent): void { 
      for (var i:int = 1; i < 8; i++){ 
       list.addItem ({ label: 'Track ' + i }); 
      } 
     } 
     private function list_on_Change(e:Event): void { 
      trace('You selected : ' + e.target.selectedItem.label); 
     } 
    } 

} 

希望可以帮助。

您分享的代码不会以任何方式工作。因为您错误地创建了按钮类。您尝试添加列表并尝试访问文本字段。无论如何，这是不可能的。相反，您可以添加一个文档类。

package { 

    import flash.display.MovieClip; 


    public class Main extends MovieClip { 

     var list:List; 
     public function Main() { 
      butdin.addEventListener (MouseEvent.CLICK, sayit); 
     } 
     private function sayit (e:MouseEvent):void 
     { 


      list = new List(); 
      list.setSize (361,291); 
      list.move (421, 254); 
      //var i:uint; 
      //for (i=1; i<8; i++) 
      //{ 
      //list.addItem ({ label: "Track " + i }); 
      //} 
      list.addItem ({ label: "Track 1" });//Opens swf file 1.swf in next frame on stage 
      list.addItem ({ label: "Track 2" });//Opens swf file 2.swf in next frame on stage 
      list.addItem ({ label: "Track 3" }); 
      list.addItem ({ label: "Track 4" }); 
      list.addItem ({ label: "Track 5" }); 
      list.addItem ({ label: "Track 6" }); 
      list.addItem ({ label: "Track 7" }); 

      addChild (list); 
      list.addEventListener (Event.CHANGE, itemClick); 


     } 
     private function itemClick() 
     { 

      status_txt.text = "You selected: " + event.target.selectedItem.label; 

     } 
    } 

} 

确保所有必要的软件包进口，按钮和文本字段使用实例名称
