FLASH BUILDER AIR 打开本地文件及保存列表

首先需要一个容器

<s:BorderContainer id="container" width="100%" height="100%" backgroundAlpha="0" borderAlpha="0">                
</s:BorderContainer>

AS代码：

先添加侦听

container.addEventListener(NativeDragEvent.NATIVE_DRAG_ENTER, nativeDragEnterHandler);
container.addEventListener(NativeDragEvent.NATIVE_DRAG_DROP, nativeDragDropHandler);
 1 private function nativeDragEnterHandler(e:NativeDragEvent):void
 2             {
 3                 NativeDragManager.dropAction = NativeDragActions.COPY;
 4                 NativeDragManager.acceptDragDrop(container);
 5             }
 6             
 7             private function nativeDragDropHandler(e:NativeDragEvent):void
 8             {
 9                 var clip:Clipboard = e.clipboard;
10                 if(clip.hasFormat(ClipboardFormats.FILE_LIST_FORMAT))
11                 {
12                     var fileList:Array = clip.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
13                     var fileLen:uint = fileList.length;
14                     
15                     var item:Object;
16                     var urlStr:String;
17                     var hasLen:int = list_DG.length;
18                     for (var i:uint = 0; i < fileLen; i ++) 
19                     {
20                         var file:File = fileList[i] as File;
21                         urlStr = new String(file.nativePath);
22                         if (urlStr.slice( -5) == ".ttpl") {
23                             trace("212")//loadXML(urlStr);
24                         }else{
25                             item = new Object();
26                             item.num = hasLen+i+1;
27                             item.name = urlStr.slice(urlStr.lastIndexOf("\\")+1,-4);
28                             item.name = item.name.slice(item.name.lastIndexOf("/")+1);
29                             item.url = file.url.slice(-4)==".mp3"?"mp3.png":file.url;
30                             item.snd = file.url.slice(-4)==".mp3"?file.url:"";
31                             item.type = file.url.slice(-4)==".mp3"?0:1;//0mp3 1pic
32                             
33                             list_DG.addItem(item);//list_DG是Arraycollection
34                         }
35                     }
36                     saveList();//保存列表xml类型
37                 }
38             }

savelList:

 1 private function saveList():void{
 2                 var list:XML = <ImgList></ImgList>;    
 3                 
 4                 for(var i:int = 0; i<list_DG.length;i++){
 5                     var item:XML = <item time="0:00" />;
 6                     item.@name = list_DG.getItemAt(i).name;
 7                     item.@url = list_DG.getItemAt(i).url;
 8                     item.@snd = list_DG.getItemAt(i).snd;
 9                     item.@type = list_DG.getItemAt(i).type;
10                     list.appendChild(item);
11                 }
12                 var file:File = new File(File.applicationDirectory.nativePath+"/data/last.xml");
13                 var fs:FileStream = new FileStream();
14                 fs.open(file, "write");
15                 fs.writeUTFBytes(list.toXMLString());
16                 fs.close();    
17             }
