android gson使用

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
