第一步注册:  compile 'com.google.code.gson:gson:2.6.2'

第二步初始化:

 Gson gson = new GsonBuilder()
.setLenient()// json宽松
.enableComplexMapKeySerialization()//支持Map的key为复杂对象的形式
.serializeNulls() //智能null
.setPrettyPrinting()// 调教格式
.disableHtmlEscaping() //默认是GSON把HTML 转义的
.create();

1.简单json解析:

[{username:"arthinking",userId:"001"},{username:"Jason",userId:"002"}];

public class User {
private String username ;
private int userId ;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
}

解析:

Type listType = new TypeToken<LinkedList<User>>(){}.getType();
Gson gson = new Gson();
LinkedList<User> users = gson.fromJson(jsonData, listType);
for (Iterator iterator = users.iterator(); iterator.hasNext();) {
User user = (User) iterator.next();
System.out.println(user.getUsername());
System.out.println(user.getUserId());
}

复杂一点的json

gson使用

 Gson gson = new Gson();
OtherDetail d = gson.fromJson(jsonString,Detail.class);//取值
