EditText внутри alertDialogue не показывает программную клавиатуру в Android

У меня есть текст редактирования внутри диалогового окна предупреждения для некоторого ввода пользователя. Но когда я нажимаю на текст редактирования, он не показывает мягкую клавиатуру.

Если в диалоговом окне установлен один и тот же текст редактирования, он отображает клавиатуру, когда редактируемый текст сфокусирован.
