Answer 1

您应该将原始资源放入/res/raw 文件夹，然后重建您的 R 类并从那里得到它们。

http://developer.android.com/guide/topics/resources/providing-resources.html

节选:

原始/
以原始形式保存的任意文件。要使用原始 InputStream 打开这些资源，请使用资源 ID(即 R.raw.filename)调用 Resources.openRawResource()。

但是，如果您需要访问原始文件名和文件层次结构，您可以考虑将一些资源保存在 assets/目录中(而不是 res/raw/)。 assets/中的文件没有资源 ID，因此您只能使用 AssetManager 读取它们。
