Android Parcel:编写数组列表

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

    // 构造函数、getter和setter方法

    // 实现Parcelable接口的方法
    @Override
    public int describeContents() {
        return 0;
    }

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

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

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

    private Person(Parcel in) {
        name = in.readString();
        age = in.readInt();
    }
}

ArrayList<Person> personList = new ArrayList<>();
personList.add(new Person("John", 25));
personList.add(new Person("Jane", 30));

Intent intent = new Intent(this, TargetActivity.class);
intent.putParcelableArrayListExtra("personList", personList);
startActivity(intent);

ArrayList<Person> personList = getIntent().getParcelableArrayListExtra("personList");
