类实现Parcelable接口在Intent中传递

类实现了Parcelable接口就可以在Intent中传递   只要在类的定义中实现Parcelable接口

代码

 1 package entity;
 2
 3 import android.os.Parcel;
 4 import android.os.Parcelable;
 5
 6 public class Person implements Parcelable {
 7
 8     private int id;
 9     private String name;
10     private String pass;
11
12     public Person() {
13         super();
14         // TODO Auto-generated constructor stub
15     }
16
17     public Person(int id, String name, String pass) {
18         super();
19         this.id = id;
20         this.name = name;
21         this.pass = pass;
22     }
23
24     public int getId() {
25         return id;
26     }
27
28     public void setId(int id) {
29         this.id = id;
30     }
31
32     public String getName() {
33         return name;
34     }
35
36     public void setName(String name) {
37         this.name = name;
38     }
39
40     public String getPass() {
41         return pass;
42     }
43
44     public void setPass(String pass) {
45         this.pass = pass;
46     }
47
48     @Override
49     public String toString() {
50         return "Person [id=" + id + ", name=" + name + ", pass=" + pass + "]";
51     }
52          //----------实现内容描述
53     @Override

62         dest.writeInt(id);
63         dest.writeString(name);
64         dest.writeString(pass);
65
66     }
67     // 添加一个静态成员,名为CREATOR,该对象实现了Parcelable.Creator接口
68     public static final Parcelable.Creator<Person> CREATOR = new Creator<Person>() {
69
70         @Override
71         public Person[] newArray(int size) {
72             // TODO Auto-generated method stub
73             return new Person[size];
74         }
75
76         @Override
77         public Person createFromParcel(Parcel source) {
78             // 从Parcel中读取数据，返回person对象    --------------按顺序读
79             return new Person(source.readInt(), source.readString(),
80                     source.readString());
81         }
82     };
