Проблема с передачей массива из активности во фрагмент

0 голосов
/ 18 января 2020

Я получаю очень странную ошибку, хотя код выглядит нормально (на мой взгляд). Я получаю эту ошибку

java.lang.ArrayIndexOutOfBoundsException: length=1; index=1

Я сохраняю данные из нескольких EditText -й в моем фрагменте, затем помещаю их в array и отправляю в родительские действия, которые затем отправляют их в моей базе данных. Затем после нажатия button, чтобы показать мне фрагмент с текстом из array, приложение вылетает. Вот мой код:

Прочее. java

public class Others extends AppCompatActivity {

    /*public static List EXTRA_DATA_arr2= Collections.singletonList("com.example.schedule.example.EXTRA_DATA_arr2");
    public static List EXTRA_DATA_arr3= Collections.singletonList("com.example.schedule.example.EXTRA_DATA_arr3");
    public static List EXTRA_DATA_arr4= Collections.singletonList("com.example.schedule.example.EXTRA_DATA_arr4");

Компилятор указывает на метод Set(). Я пробовал разные вещи, но ни одна из них не сработала. Пробовал отладку, которая закончилась неудачно. Надеюсь, вы можете помочь мне. Заранее спасибо
