Извлечение значений из объекта класса Singleton с использованием Gson

Question

Я использую gson для анализа ответа json. Хотя все работает нормально. Я придерживался ситуации, когда нужно получить данные из объекта класса singleton.

Мой Singleton класс ниже:

общественного класса ReadingTest {

public List<QuestionBean> Question; 

public static List<ReadingTest> arrayReadingTestFromData(String str, String key) { 

    try { 
     JSONObject jsonObject = new JSONObject(str); 
     Type listType = new TypeToken<ArrayList<ReadingTest>>() { 
     }.getType(); 

     return new Gson().fromJson(jsonObject.getString(str), listType); 

    } catch (JSONException e) { 
     e.printStackTrace(); 
    } 

    return new ArrayList(); 


} 

public String getTest() { 
    return Test;

    this.Test = Test;

Я использовал библиотеку Okhttp для работы в сети.

Ниже приведен код для разбора JSON с gson

Gson gson = new Gson(); 
ReadingTest[] readingTest = gson.fromJson(responseData,ReadingTest[].class); 

responseData: - это JSON ответ я получаю от сервера.

Я вижу все в объекте ReadingTest, но не знаю, как извлечь значения из этого объекта. Любая помощь будет оценена по достоинству.

Спасибо

Answer 1

Вы можете извлечь содержимое из массива любого объекта, используя там позицию так:

readingTest[position].<requestedValueGetMethod>(); 

, например, если хотите, чтобы получить тестовую строку, вы получите его с помощью getTest() метода, как это :

readingTest[position].getTest(); 

Все атрибуты ther могут использоваться аналогичным образом.
