TimePicker отлично работает на версии 4 android, но в ошибке версии 2.3. (Android)

У меня есть код, который отображает «TimePicker». Он позволяет установить минимальное и максимальное значение при выборе часа с 1,15 до 11,30, а также позволяет установить интервал до 15 минут. в минутах. Код отлично работает на версии 4 Android, когда TimePicker работает на прокрутке и в версии Android 2.3 TimePicker, когда отображается с кнопками «плюс» и «минус», когда вы нажимаете одну из этих кнопок на Exeption. Скажите, что делать в коде для запуска в новых и старых версиях Android?TimePicker отлично работает на версии 4 android, но в ошибке версии 2.3. (Android)

вот код:

Вы зацикливание. Ваш onTimeChanged() звонит updateTime() на таймер, который, в свою очередь, приводит к другому вызову onTimeChanged().

Один из способов исправить это - добавить булевский флаг в свой класс, чтобы предотвратить рекурсивные вызовы updateTime(). Что-то вроде:

boolean mIsOnTimeChanged; 

@Override 
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { 
    if (!mIsOnTimeChanged) { 
    mIsOnTimeChanged = true; 

    // your regular onTimeChanged() here 

    mIsOnTimeChanged = false; 
    } 
}
