android - 如何传递包含对象列表的可打包对象？

Question

我在下面创建了一个 Parcelable 对象，我的对象包含一个 List 产品。在我的构造函数中，如何处理为 List 重新创建 Parcelable？

我已经检查了包裹中所有可用的方法，所有可用的方法都是 readArrayList(ClassLoader)。我不确定这是否是最好的方法，您的建议将不胜感激。

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 ???????;
    }
}

如果类 Product 与 parcelable 协议(protocol)兼容，则应根据文档进行以下操作。

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