列出 sdcard 中的所有文件

Question

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

这会打印类似这样的内容

   /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白痴的事情，但我不知道是什么...

我想列出SD卡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

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

您可能指的是file.getName()。
