- Can the Android Layout folder contain subfolders? 18 answers
Of course I can right click the raw folder and add new folder but when I export the project, the APK file does not contain the new sub folder.
回答1:
You can't.
The folders in /res/ have a predefined structure, and you can't add subfolders.
However, seeing as this is the raw folder, you may want to look into using the assets folder, in which sub folders are supported.
Keep in mind thought that by using assets you won't be able to use R.*.* references anymore. You will have to go through the AssetManager.
