android activity传递实体类对象

通过实现Parcelable接口序列化对象的步骤：

1、实现Parcelable接口。
2、并且实现Parcelable接口的public
 void writeToParcel(Parcel dest, int flags)方法 。
3、自定义类型中必须含有一个名称为CREATOR的静态成员，该成员对象要求实现Parcelable.Creator接口及其方法。

public class Person implements Parcelable {

 

    public static final Parcelable.Creator<Person> CREATOR = new Creator<Person>() {

 

        @Override

        public Person[] newArray(int size) {

            return null;

        }

 

        @Override

        public Person createFromParcel(Parcel source) {

            Person result = new Person();

            result.age = source.readInt();

            result.name = source.readString();

            result.address = source.readParcelable(Address.class.getClassLoader());

            return result;

        }

    };

    private Address address;

    private String name;

    private int age;

 

    @Override

    public int describeContents() {

        return 0;

    }

 

    public Address getAddress() {

        return address;

    }

 

    public void setAddress(Address address) {

        this.address = address;

    }

 

    @Override

    public void writeToParcel(Parcel dest, int flags) {

        dest.writeInt(age);

        dest.writeString(name);

        dest.writeParcelable(address, PARCELABLE_WRITE_RETURN_VALUE);

    }

 

    public String getName() {

        return name;

    }

 

    public void setName(String name) {

        this.name = name;

    }

 

    public int getAge() {

        return age;

    }

 

    public void setAge(int age) {

        this.age = age;

    }

 

    @Override

    public String toString() {

        return "Person [address=" + address + ", name=" + name + ", age=" + age

                + "]";

    }

 

}

传递实体类：

Bundle bundle = new Bundle();
// bundle.putSerializable(TITLE, title);
bundle.putParcelable(TITLE, title);
context.startActivity(new Intent(context, target).putExtras(bundle));

接收：

mCollectParamObj = (CollectParamObj) getIntent().getParcelableExtra(
"title");
