1. Serializable方式

Serializable是序列化的意思，含义是将一个对象转化为可存储或是可传输的状态，序列化后的对象可以在网络上进行传输，也可以存储到本地。

    private void serializeData() {
        Person person = new Person();
        person.setAge(1);
        person.setName("TOM");
        Intent intent = new Intent(this, SerializableTestActivity.class);
        intent.putExtra("person_data", person);
        startActivity(intent);
    }

    private void deSerializeData() {
        Person person = (Person) getIntent().getSerializableExtra("person_data");
    }

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

    geterAndSetter(){
        ......
    }
}

2 Parcelable方式

Parcelable 方式也可以用于传递对象，不同于序列化，Parcelable是将一个完整的对象进行分解，其每一部分都是intent支持的数据类型

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

    protected Person(Parcel in) {
        name = in.readString();
        age = in.readInt();
    }
    
    @Override
    public int describeContents() {
        return 0;
    }

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

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

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

    private void getParseData() {
        Person person = (Person) getIntent().getParcelableExtra("person_data");
    }
