如何传递一个对象从一个活动到另一个机器人 [英] How to pass an object from one activity to another on Android

问题描述

我想对发送的对象我的客户的从一个活动类工作，并在另一个显示它活动。

I am trying to work on sending an object of my customer class from one Activity and display it in another Activity.

在code为客户类：

public class Customer {

    private String firstName, lastName, Address;
    int Age;

    public Customer(String fname, String lname, int age, String address) {

        firstName = fname;
        lastName = lname;
        Age = age;
        Address = address;
    }

    public String printValues() {

        String data = null;

        data = "First Name :" + firstName + " Last Name :" + lastName
        + " Age : " + Age + " Address : " + Address;

        return data;
    }
}

我想从一个活动另活动发送其对象到另一个，然后显示数据。

I want to send its object from one Activity to another and then display the data on the other Activity.

我怎样才能做到这一点？

How can I achieve that?

推荐答案

一个选项可以让你自定义的类实现序列化接口，然后你可以通过在对象实例意图额外使用 putExtra（序列化。）的意向＃putExtra（）法的变种。

One option could be letting your custom class implement the Serializable interface and then you can pass object instances in the intent extra using the putExtra(Serializable..) variant of the Intent#putExtra() method.

伪code

//To pass:
intent.putExtra("MyClass", obj);

// To retrieve object in second Activity
getIntent().getSerializableExtra("MyClass");
