android - 在空中为android加载外部图片

Question

我需要从移动android 的sd 卡中创建的应用程序目录中的文件夹加载图像

PC端可以，手机端不行

一些解决方案？

var imagesFin:File = File.applicationStorageDirectory.resolvePath("appImages/");
var files:Array = imagesFin.getDirectoryListing();

 for (var i:uint = 0; i < files.length; i++){


  var picLoader = new Loader();
  picLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadPicture);
  picLoader.load(new URLRequest(files[i].nativePath));

 }
 function loadPicture(event:Event):void {

 var imgAtual = event.target.content;
 ContainerImagesList.addChild(imgAtual);
}

Answer 1

这对我有用:

var bytes:ByteArray = new ByteArray();
var myFileStream:FileStream = new FileStream();
var myFile:File = File.documentsDirectory.resolvePath(YOUR_PATH);

myFileStream.addEventListener(Event.COMPLETE, fileCompleteHandler)
myFileStream.openAsync(myFile, FileMode.READ);

function fileCompleteHandler(event:Event):void 
{
    myFileStream.readBytes(bytes);

    var loader:Loader = new Loader();
    loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageLoaded);
    loader.loadBytes(bytes);

    function imageLoaded(e:Event):void
    {
        addChild(Bitmap(loader.content));
        myFileStream.removeEventListener(Event.COMPLETE, fileCompleteHandler);
        myFileStream.close();
    }
}

干杯!
