Question

I have created a Parcelable object below, my object contains a List of Products. In my constructor how do I handle re-creating my Parcelable for the List?

I have checked all of the methods available from the parcel and all that is available is readArrayList(ClassLoader). I’m not sure if this is the best approach, your advice would really be appreciated.

public class Outfits implements Parcelable {

    private String url;
    private String name;
    private List<Product> products;

    public String getUrl() {
        return url;
    }
    public void setUrl(String url) {
        this.url = url;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public List<Product> getProducts() {
        return products;
    }
    public void setProducts(List<Product> products) {
        this.products = products;
    }

    public void writeToParcel(Parcel dest, int flags) {
        Log.v("", "writeToParcel..." + flags);
        dest.writeString(url);
        dest.writeString(name);
        dest.writeList(products);
    }


    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public Outfits createFromParcel(Parcel in) {
            return new Outfits(in);
        }

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

    @Override
    public int describeContents() {
        return 0;
    }

    /*** Here how do I populate my List of Products ***/
    private Outfits(Parcel in) {
        url = in.readString();
        name = in.readString();
        products = in.read ???????;
    }
}

Answer 1

If class Product is compatible with parcelable protocol, following should work according to documentation.

products = new ArrayList<Product>();
in.readList(products, Product.class.getClassLoader());
