【问题描述】：

            if (folder.listFiles() != null) {
                for (File file : folder.listFiles()) {
                    if (file.isFile()) {
                        Log.v("vvv", "file with name " + folder.getName() + " in path " + folder.getAbsolutePath());
                    } 
                    }
                }

这会打印出这样的东西

   /vvv     ( 3940): Folder with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): file with name .thumbnails in path /sdcard/DCIM/.thumbnails
V/vvv     ( 3940): Folder with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera
V/vvv     ( 3940): file with name Camera in path /sdcard/DCIM/Camera

我在代码中做了一些愚蠢的事情，但我不知道是什么......

我想列出 sdcard 中的所有文件夹和所有文件...

你能帮我找到我的错误吗，谢谢

【解决方案1】：

for (File file : folder.listFiles()) {
    if (file.isFile()) {
       Log.v("vvv", "file with name " + folder.getName() + " in path " + folder.getAbsolutePath());
    } else {
                                        ^^^^^^

你的意思可能是file.getName()。
