谁能告诉我如何将真实设备图像文件夹的路径放在 imageLoader.getInstance().displayImage(path, imageView, options); 中。因为我使用 sd 卡图像路径传递参数，但 UniversalImageLoader E/ImageLoader：UIL 默认不支持方案（协议）[/storage/emulated/0/classnkk_images/1_20150928163482053.png]。您应该自己实现此支持 (BaseImageDownloader.getStreamFromOtherSource(...))

这是我的 Logcat

【解决方案1】：

使用file:// 方案，如the documentation 所示。

"file:///mnt/sdcard/image.png" // from SD card

【讨论】：

但是我的图像文件夹在内部存储中，所以我怎样才能获得路径，ImageLoader 说没有这样的文件或目录。
@androidTag: "how can i get the path" -- 给定一个名为f 的File 对象指向文件，使用Uri.fromFile(f).toString()。
