Ошибка Attempt to invoke virtual method 'java.lang.Object android.content.Context.getSystemService(java.lang.String)' on a null object reference

Не создаётся view для диалога. Один и тот же метод addAndEditSchedule вызывается в двух местах. По нажатию на fab во фрагменте и из Aдаптера при нажатие на элемент списка Recycler View. После нажатия fab всё отрабатывает корректно, а после нажатия на view списка выпадает ошибка:
