Android-AS3 Air浏览SD卡上的文件？

希望能够使用as3 air从用户手机中浏览和选择文件.

此代码仅弹出一个上传框,并显示“未找到文件”.但是我知道我的手机上有一个zip,所以它一定不能选择正确的文件夹路径.如何更改它以使其能够访问整个手机？

function unzip_init():void{

    fileFilter = new FileFilter("selected your zip file.", "*.zip; *.gz2; *.bz2;");
    file = new File();
    //file.browseForDirectory("Choose a directory"); // Only got me the directory path
    file.browseForOpen("Open", [fileFilter]);
    file.addEventListener(Event.SELECT, onSelectedFile);
}

解决方法:

要从SD卡获取所有mp3文件

var ROOT:File = File.documentsDirectory.resolvePath("/sdcard/");
var FILES:Array = ROOT.getDirectoryListing();
var TrackN:int;
var SUBFOLDER:String;

for (var i:int = 0; i < FILES.length; i++)
{
    var File_Ext:String;
    File_Ext = "" + FILES[i].extension;

    if (File_Ext.toLowerCase() == "mp3")
    {
      TrackN++;
      list.addItem( { label:FILES[i].name, data:TrackN, Song:FILES[i].url} );
    }

    if (FILES[i].isDirectory == true)
    {
      SUBFOLDER = "" + FILES[i].nativePath;
      getSubfolders();
    }

    function getSubfolders()
    {
        var SUBF:File = File.documentsDirectory.resolvePath(SUBFOLDER);
        var FLIST:Array = SUBF.getDirectoryListing();

        for (var s:int = 0; s < FLIST.length; s++)
        {
            File_Ext = "" + FLIST[s].extension;

            if (File_Ext.toLowerCase() == "mp3")
            {
                TrackN++;
                list.addItem( { label:FLIST[s].name, data:TrackN, Song:FLIST[s].url} );
            }

            if (FLIST[s].isDirectory == true)
            {
                SUBFOLDER = "" + FLIST[s].nativePath;
                getSubfolders();
            }
        }
    }
}
