Hey @ all!
I've got a question about Parcelling. I can't find the answer all over
the web, so you are my last hope ;)
I'll explain the problem by using an example.
These are my custom-objects:
public class Garden implements Parcelable {
int numberOfPlants;
Plant[] plants;
{...}
}
public class Plant implements Parcelable {}
public class Flower extends Plant implements Parcelable {}
public class Tree extends Plant implements Parcelable {}
Now, I'd like to send an instance of Garden from one Activity to
another.
So i have to parcel the plants[]-Array. This is possible as long as
the Array only includes instances of Plant.
My problem is that it seems to be impossible to parcel when plants[]
includes instances of Flower and Tree (subclasses of Plant) as well.
So, is it possible to do something like that?
Here's how I tried to do it (actually, I tried many more thing, but
now I am too confused to get them together :( ):
public Garden(Parcel in) {
numberOfPlants = in.readInt();
plants = new Plant[numberOfPlants];
for (int i=0; i<numberOfPlants; i++) {
//plants[i] = Plant.CREATOR.createFromParcel(in); (just another
try)
plants[i] = in.readParcelable(Plant.class.getClassLoader());
}
}
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(numberOfPlants);
for (int i=0; i<numberOfPlants; i++) {
plants[i].writeToParcel(dest, flags);
}
}
Really hope you can help me.
Thanks in advance,
mj@gue
