(Google Translate) У меня есть пользовательский PreferenceFragment с иконкой и ImageView. Этот экран управляет уведомлением о моем приложении. При нажатии на элемент отключить или включить уведомление при щелчке по ImageView (soundIcon), постоянно изменяя тип уведомления (вибрация, звук). Но когда я нажимаю на ImageView (soundIcon), я не знаю, как я могу получить позицию позиции. Вот мой код и Screeshot:PreferenceFragment getListView
