推荐答案

我猜你使用的是Android 4.0，为 .nomedia 正常运作到那时。在AOSP 错误报告的问题说明：

I'm guessing you're using Android 4.0, as .nomedia functioned properly until then. The AOSP bug report for the issue explains:

MediaScanner 在Android 4.0不能忘记已经建立索引的文件，它遇到一个 .nomedia 文件时，却并兑现它，如果它是在第一轮present。因此，解决方法是简单地重命名的目录。当然，你可以在下一次扫描后，将名称更改回来，如果你喜欢。

MediaScanner on Android 4.0 fails to forget already-indexed files when it encounters a .nomedia file, but it does honor it if it's present on the first pass. So the workaround is to simply rename the directory. Of course you can change the name back after the next scan, if you like.

更新的：我想彻底的解决办法是重命名目录后，竟强制媒体扫描。我还没有尝试过，但这样的事情应该做的伎俩：

Update: I suppose the complete solution would be to actually force a media scan after renaming the directory. I haven't tried it, but something like this should do the trick:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" +
    Environment.getExternalStorageDirectory())));
