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);

private function nativeDragEnterHandler(e:NativeDragEvent):void
            {
                NativeDragManager.dropAction = NativeDragActions.COPY;
                NativeDragManager.acceptDragDrop(container);
            }
            
            private function nativeDragDropHandler(e:NativeDragEvent):void
            {
                var clip:Clipboard = e.clipboard;
                if(clip.hasFormat(ClipboardFormats.FILE_LIST_FORMAT))
                {
                    var fileList:Array = clip.getData(ClipboardFormats.FILE_LIST_FORMAT) as Array;
                    var fileLen:uint = fileList.length;
                    
                    var item:Object;
                    var urlStr:String;
                    var hasLen:int = list_DG.length;
                    for (var i:uint = 0; i < fileLen; i ++) 
                    {
                        var file:File = fileList[i] as File;
                        urlStr = new String(file.nativePath);
                        if (urlStr.slice( -5) == ".ttpl") {
                            trace("212")//loadXML(urlStr);
                        }else{
                            item = new Object();
                            item.num = hasLen+i+1;
                            item.name = urlStr.slice(urlStr.lastIndexOf("\")+1,-4);
                            item.name = item.name.slice(item.name.lastIndexOf("/")+1);
                            item.url = file.url.slice(-4)==".mp3"?"mp3.png":file.url;
                            item.snd = file.url.slice(-4)==".mp3"?file.url:"";
                            item.type = file.url.slice(-4)==".mp3"?0:1;//0mp3 1pic
                            
                            list_DG.addItem(item);//list_DG是Arraycollection
                        }
                    }
                    saveList();//保存列表xml类型
                }
            }

savelList:

private function saveList():void{
                var list:XML = <ImgList></ImgList>;    
                
                for(var i:int = 0; i<list_DG.length;i++){
                    var item:XML = <item time="0:00" />;
                    item.@name = list_DG.getItemAt(i).name;
                    item.@url = list_DG.getItemAt(i).url;
                    item.@snd = list_DG.getItemAt(i).snd;
                    item.@type = list_DG.getItemAt(i).type;
                    list.appendChild(item);
                }
                var file:File = new File(File.applicationDirectory.nativePath+"/data/last.xml");
                var fs:FileStream = new FileStream();
                fs.open(file, "write");
                fs.writeUTFBytes(list.toXMLString());
                fs.close();    
            }
