Just call intent.getParcelable() again.

Hi,
I've implemented parcelable on a class of mine per the doc
instructions, works fine:
public class MyParcelable implements Parcelable {
...
public static final Parcelable.Creator CREATOR
= new Parcelable.Creator() {
public MyParcelable createFromParcel(Parcel in) {
return new MyParcelable(in);
}
...
};
}
I'm interested in the createFromParcel() method. I pass an instance of
MyParcelable to a new activity like this:
Intent intent = new Intent(...);
intent.putExtra("key", myParcelableInstance);
startActivity(intent);
and pick it up from the new activity like this:
MyParcelable mp =
(MyParcelable)getIntent().getExtras().getParcelable("key");
I'd like to make a copy of the MyParcelable instance, like so:
MyParcelable mp2 = new MyParcelable(mp);
but I haven't implemented a copy constructor. However, the
createFromParcel() method which I did implement is almost like a copy
constructor. I'm wondering if I can use it make a copy, but I can't
figure out how to get a Parcel instance from the intent extras:
MyParcelable mp2 =
MyParcelable.CREATOR.createFromParcel(
getIntent().getExtras().getParcelable("key")); // ? just
need a parcel ?
it's not the greatest idea, just wondering if it's possible to avoid
making another method for my class which will almost be identical to
what's already implemented for the Parcelable interface,
Thanks
