You can't save a layout. You can save a layout id- but I wouldn't suggest it. Resource ids are not stable across builds, so any update would break it. Your best bet is to create an enum with whatever values you wish it to have, save the enum, and later on convert the string back into an enum when you read it in. Then hold a map<enum, resourceId> in code that maps to the correct resource id.
