Ошибка при получении данных слушателя из базы данных в Blackberry

Question

Я пытался последние три дня, но мне не удалось решить эту проблему, редактировал таблицы и запросы.

Я использовал перстлит для хранения данных;Я создал таблицы и запросы для требуемого класса;

Теперь я прослушиваю контакты в мобильном телефоне и могу получать данные только в этом классе, но не могу получить информацию восновной класс или где-нибудь в проекте, хотя я назвал класс.Кто-нибудь может мне помочь с этой проблемой?

Это моя программа

Я надеюсь, что вы поняли мою проблему

Когда я выбрал "ContactlistdatabaseQueries.selectWholeContactlist ();»этот метод в любом основном классе, я не могу получить данные в базе данных, ответ, когда я получаю, равен 0., но мне нужно получить значение сохраненных данных, то есть количество вставленных строк.

Answer 1

у меня есть проблема, это не что иное, как просто изменение базы данных, я использовал perstlite в проблеме, но постоянный будет лучше для вышеупомянутой проблемы
