XML не отображает сохраненные данные SQLite

Question

У меня есть XML, который должен отображать час из данных TimePicker, но каждый раз, когда я пытаюсь просмотреть данные, которые он заставляет закрывать. Я сузил проблему до неправильной настройки в своих XML-файлах, но я не могу исправить эту проблему и не закрывать приложение.

Answer 1

Элемент пользовательского интерфейса "@+id/timeEdit", определенный в макете view_country.xml - это TextView. Вы делаете ставку до android.widget.TimePicker в своей деятельности ViewCountry.

Существует еще один элемент пользовательского интерфейса с одинаковым идентификатором («@ + идентификатор/timeEdit»), который на самом деле IS TimePicker, но она расположена в макете для AddEditCountry деятельности.

Проверьте свой макет и код ViewCountry, возможно, элемент @+id/timeEdit не должен быть TextView, или вы должны отдать его TextView в свой метод onCreate.
