Новичок в разработке для Android и не может понять, как заставить TimePicker всплывать при нажатии элемента / View в моем элементе RecyclerView.У меня есть фрагмент с RecyclerView, и я следовал https://developer.android.com/guide/topics/ui/controls/pickers,, но когда я щелкаю по элементу, экран просто немного тускнеет, и все.Средство выбора никогда не отображается.
Спасибо.
