数据中的JSON
数组。缩短后的JSON
如下所示,每个数组并没有显示所有数据以保存滚动
如何访问LeagueTable数组中的值?

我一直在使用Gson
(dataRead是作为字符串的json数据)
System.out.println(dataRead);
Data data = new Gson().fromJson(dataRead, Data.class);
System.out.println(data.leagueTable[0].team);
我的Data
类看起来像这样
public class Data {
LeagueTable[] leagueTable;
public Data(LeagueTable[] leagueTable) {
this.leagueTable=leagueTable;
}
public static class LeagueTable{
String team;
int played, gamesWon, gamesDraw, gameLost, goalsFor, goalsAgainst, goalsDifference, points;
public LeagueTable(String team, int played, int gamesWon, int gamesDraw, int gameLost, int goalsFor,
int goalsAgainst, int goalsDifference, int points) {
this.team = team;
this.played = played;
this.gamesWon = gamesWon;
this.gamesDraw = gamesDraw;
this.gameLost = gameLost;
this.goalsFor = goalsFor;
this.goalsAgainst = goalsAgainst;
this.goalsDifference = goalsDifference;
this.points = points;
}
}
}
我应该得到Comber YM II
,但是我一直得到NullPointerException
。
答案 0 :(得分:0)
您需要创建包含Root
属性的data
类。参见以下模型:
class Root {
private Data data;
// getters, setters, toString
}
class Data {
LeagueTable[] leagueTable;
// getters, setters, toString
public static class LeagueTable{
String team;
int played, gamesWon, gamesDraw, gameLost, goalsFor, goalsAgainst, goalsDifference, points;
// getters, setters, toString
}
}
您可以如下将其反序列化:
Data data = new Gson().fromJson(dataRead, Root.class).getData();
