Parcelable List that contains a custom object

I am trying to pass data (ArrayList) between Activities on Android

All works fine when the class that implements Parcelabledoesn´t contains custom objects (Shop), but what do I have to do if my class contains one?

Shop

public Shop(Parcel in) {
    this.id  = in.readString();
    this.name = in.readString();
    this.type = in.readString();
    this.lat= in.readDouble();
    this.long= in.readDouble();
}
@Override
public void writeToParcel(Parcel dest, int flags) {

    dest.writeString(this.id);
    dest.writeString(this.name);
    dest.writeString(this.type);
    dest.writeDouble(this.lat);
    dest.writeDouble(this.long);
}

@SuppressWarnings("rawtypes")
public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
    public Shop createFromParcel(Parcel in) {
        return new Shop(in);
    }

    public Shop[] newArray(int size) {
        return new Shop[size];
    }
};

And here is my other class Offer which is the one that contains an object of Shop

public Offer(Parcel in) {
    this.id  = in.readInt();
    this.title = in.readString();
    this.myShop = in.read.......();
}


@Override
public void writeToParcel(Parcel dest, int flags) {

    dest.writeInt(this.id);
    dest.writeString(this.title);
    dest.write......(this.myShop);
}

Which data type should I read and write ?

Thank you very much!

Your Shop class should implement Parcelable and you should use

public Offer(Parcel in) {
    this.id  = in.readInt();
    this.title = in.readString();
    this.myShop = in.readParcelable(Shop.class.getClassLoader());
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeInt(this.id);
    dest.writeString(this.title);
    dest.writeParcelable(this.myShop, flags);
}
