My Android project duplicated declarations between Enum and string.xml

Question

I have String arrays to use for Spinner or such.

 <string-array name="Animal"> <item >Cat</item> <item >Dog</item> <item >Rabbit</item> <item >Bird</item> </string-array> 

I have a container class that contains values ​​entered by the user or selected from Spinner . Member variables are mostly primitives or Enum .

 public class Container { protected int index; protected int age; protected String name; protected Animal pet; } 

Here's how one of the Enum classes is defined (note that this is a simpler version, and in my actual code there are a few more methods or variables, and each Enum instance is uppercase, like CAT).

 public enum Animal { Cat, Dog, Rabbit, Bird, } 

As you can see, I am practically repeating the same thing in Enum and XML. This is not very good by DRY. Who should I remove, and how to do it?

At this point, I tend to preserve Enum , as it is functionally more universal than XML, and no less maintained. The only possible problem I can worry about is its performance. They may require more memory, as well as some additional encoding features.

If you want to avoid duplication, you must save Enum, and then you fill in the program key using for(Animal animal:Animal.values()) {...} .

You can use the name Enum as a key to get a localized label or similar things.
