android下xstream转换对象和xml

特意构造一个复杂一些的对象结构，将其转换为xml

1.  @XStreamAlias("group")  
2.  publicclassGroup {  
3.  
4.    @XStreamAsAttribute 
5.    privateString     name;  
6.  
7.    privateList users;  
8.  
9.    publicString getName() {  
10.        returnname;  
11.    }  
12.  
13.    publicvoidsetName(String name) {  
14.        this.name = name;  
15.    }  
16.  
17.    publicList getUsers() {  
18.        returnusers;  
19.    }  
20.  
21.    publicvoidsetUsers(List users) {  
22.        this.users = users;  
23.    }  
24.  
25.

1.  @XStreamAlias("user")  
2.  publicclassUser {  
3.    @XStreamAsAttribute 
4.    privateString  name;  
5.    privateString  userName;  
6.    privateString  password;  
7.      
8.    @XStreamOmitField 
9.    privateInteger age;  
10.  
11.    publicString getName() {  
12.        returnname;  
13.    }  
14.  
15.    publicvoidsetName(String name) {  
16.        this.name = name;  
17.    }  
18.  
19.    publicString getUserName() {  
20.        returnuserName;  
21.    }  
22.  
23.    publicvoidsetUserName(String userName) {  
24.        this.userName = userName;  
25.    }  
26.  
27.    publicString getPassword() {  
28.        returnpassword;  
29.    }  
30.  
31.    publicvoidsetPassword(String password) {  
32.        this.password = password;  
33.    }  
34.  
35.    publicInteger getAge() {  
36.        returnage;  
37.    }  
38.  
39.    publicvoidsetAge(Integer age) {  
40.        this.age = age;  
41.    }  
42.

1.  用来定义xml节点的名字  
2. 表示此属性是一个属性，而不是子节点  
3. 表示忽略此字段  
4. 1.1.3.1.jar，但是在pc下执行，就需要xmlpull-1.1.3.1.jar，因为PC上的jdk没有pull库
