   {"type":"earnings","info":{"earnings":58.9,"dividends":2245.82,"gains":0,"expenses":2024.12,"shares_bought":0,"shares_bought_user_count":0,"shares_sold":0,"shares_sold_user_count":0},"created":"2011-05-20 11:59:17"}

Я использую Gson, но это не массив и не простой json, я не знаю, например, как получить доход.Тост не работает: Уведомление n = ...;Toast.makeText (getApplicationText (), Double.toString (n.getData (). Get (i) .getEarnings (), Toast.SHORT) .show не работает. Это отображение 0.0 Моя проблема немного похожа на это, но яна самом деле не получил его ответ: ссылка , вот мой класс:

import java.util.List; 

 public class Profile_notifications_data {
private String type;

private double dividends;

Вот класс Java для преобразования имеющейся у вас строки JSON в объект Java. 

ProfileNotificationData profileNotificationData = new Gson().fromJson("YOUR JSON STRING", ProfileNotificationData.class);

Вы можете получить доход, позвонив по номеру profileNotificationData.info.earnings;. 

public class ProfileNotificationData {
    public String type;
    public Info info;
    public String created;

    public static class Info{
        public double earnings;
        public double dividends;
        public double gains;
        public double expenses;
        public int shares_bought;
        public int shares_bought_user_count;
        public int shares_sold;
        public int shares_sold_user_count;
    }
}
...
