If you really need to, you could serialize an enum as a String, using name() and valueOf(String), as follows:

 class Example implements Parcelable { 
   public enum Foo { BAR, BAZ }

   public Foo fooValue;

   public void writeToParcel(Parcel dest, int flags) {
      parcel.writeString(fooValue == null ? null : fooValue.name());
   }

   public static final Creator CREATOR = new Creator() {
     public Example createFromParcel(Parcel source) {        
       Example e = new Example();
       String s = source.readString(); 
       if (s != null) e.fooValue = Foo.valueOf(s);
       return e;
     }
   }
 }

This obviously doesn't work if your enums have mutable state (which they shouldn't, really).
