问题
When I create a subfolder in the layout folder, and drag an xml file to it, the generated R file doesn't seem to show the subfolder. a) is there a way to change that b) is the file and file structure still picked up by SVN and c) so, if I do it that way, can I still just refer to the object using layout?

That is because that is not supported by Android. You cannot have subfolders of resources.
PHP_Jedi's advice, though, is good (e.g., svn:ignore).
回答2:
Its all automatic.
a )The generated R class only contains static integers for each item in your layout.
b) What is picked up by svn is all up to you, but I usally put the gen folder to svn:ignore
c) if you put the gen folder and the R.java into svn you could get problems since a old version of the file can be checked in/out of the respository. This will happen if you are part of a team. So, put svn:ignore on the gen folder.
