Obyektni qanday serializatsiya qilish mumkin, uni uzatish yoki Bundle turidagi konteynerda saqlash uchun?

Androidda, obyektni Bundle turidagi konteynerda uzatish yoki saqlash uchun obyekt seriyalash mumkin bo‘lishi kerak. Asosiy seriyalash usullari:

1. Parcelable — Android uchun optimallashtirilgan interfeys, obyektlarni tezda seriyalash imkonini beradi.
2. Serializable — Java standarti interfeys, amalga oshirish osonroq, lekin kamroq samarali.

Parcelable bilan misol:

public class User implements Parcelable {
    private String name;
    private int age;

    protected User(Parcel in) {
        name = in.readString();
        age = in.readInt();
    }

    public static final Creator<User> CREATOR = new Creator<User>() {
        @Override
        public User createFromParcel(Parcel in) {
            return new User(in);
        }

        @Override
        public User[] newArray(int size) {
            return new User[size];
        }
    };

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(name);
        dest.writeInt(age);
    }
}

// Foydalanish:
Bundle bundle = new Bundle();
bundle.putParcelable("user", userObject);

Shunday qilib, obyekt Bundle ga joylashtirilishi va Android komponentlari o‘rtasida uzatilishi mumkin.
