[Android/Java] Generating Enum Values

Description

When exporting to Android enums are generated as:

public enum GenderIdEnum {
     0,  1,  2, 
  };

Versus a potential workaround:

public enum GenderIdEnum {
    Zero(0), One(1), Two(2);
    private int value;
    private GenderIdEnum(int value) {
      this.value = value;
    }
    public int getValue() {
      return value;
    }
  };

Swagger-codegen version

Using: http://editor.swagger.io/#/

Loading from URL:
https://polling.arena.razerzone.com/swagger/docs/v1

Exporting to Android.

Importing to Android Studio.

Gradle reports the enum syntax error.

Steps to reproduce

1. Go to http://editor.swagger.io/

2. File Import URL:
   https://polling.arena.razerzone.com/swagger/docs/v1

3. Generate Client Android

4. Unpack zip file

5. Import as new project in Android Studio

6. See the gradle compile error

Suggest a Fix

public enum GenderIdEnum {
    Zero(0), One(1), Two(2);
    private int value;
    private GenderIdEnum(int value) {
      this.value = value;
    }
    public int getValue() {
      return value;
    }
  };

Reproduce the issue by importing the supplied Swagger URL in editor.swagger.io and generating an Android client. Inspect the generated Java enum and the Android generation template or entry point that produces it, then verify completion by importing the client into Android Studio and confirming that Gradle compiles without the enum syntax error.
