推荐答案

Environment.getExternalStorageDirectory 会给你一个文件对应的SD卡。然后，你只需要使用 文件 的方法。

Environment.getExternalStorageDirectory will give you a File corresponding to the SDCARD. Then you'll just have to use File methods.

这应该是这样的：

File sdCardRoot = Environment.getExternalStorageDirectory();
File yourDir = new File(sdCardRoot, "yourpath");
for (File f : yourDir.listFiles()) {
    if (f.isFile())
        String name = f.getName();
        // make something with the name
}

一个小纸条建议：从奇巧及以上，这需要 READ_EXTERNAL_STORAG​​E 许可

A little note of advice : from KitKat and above, this requires the READ_EXTERNAL_STORAGE permission.
