您应该看看libgdx的ResolutionFileResolver，并且还用AssetManager（这将减轻对你的一切）。

You should look into libgdx's ResolutionFileResolver, and also use AssetManager (it will ease everything for you).

您提供它的分辨率和适当的文件夹使用，然后libgdx自动地选择与***匹配的文件夹。

You supply it resolutions and the proper folder to use, and then libgdx automagically selects the folder with the best match.

Resolution[] resolutions = { new Resolution(320, 480, ".320480"),
                          new Resolution(480, 800, ".480800"),
                          new Resolution(480, 856, ".480854") };
ResolutionFileResolver resolver = new ResolutionFileResolver(new InternalFileHandleResolver(), resolutions);
manager = new AssetManager();

这是做在libgdx的方式，你不应该接触到资源文件夹。

This is the way to do it in libgdx, you shouldn't touch the res folder.
