Answer 1

you can use enum constructor for enum to have primitive data type..

public enum DaysOfWeek {
    MONDAY(1),
    TUESDAY(2),
    WEDNESDAY(3),
    THURSDAY(4),
    FRIDAY(5),
    SATURDAY(6),
    SUNDAY(7);

    private int value;
    private DaysOfWeek(int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }

    private static final SparseArray map = new SparseArray();

    static
    {
         for (DaysOfWeek daysOfWeek : DaysOfWeek.values())
              map.put(daysOfWeek.value, daysOfWeek);
    }

    public static DaysOfWeek from(int value) {
        return map.get(value);
    }
}

you can use to pass int as extras then pull it from enum using its value.
