Я прошел аргумент "Германия", чтобы попытаться найти ошибку и дальше, но не повезло. Таким образом, пользователь выбирает страну на домашнем экране, затем запрашивает, чтобы основной класс выполнял поиск в базе данных для этой страны и загружал ее на dataScreen, когда я удаляю код базы данных поиска, приложение перемещается между экранами отлично, но с кодом базы данных поиска приложение загружает домашний экран, но затем отображает ошибки logCat, как только я нажимаю на страну, любая помощь будет отличной.
Привет ребята
Спасибо за ваши ответы, так что я сделал изменения, будучи не передать аргумент нуль на классе адаптера и изменяющие делать, пока на некоторое время, но теперь я получаю следующие ошибки в logCat:
