ОБНОВЛЕНИЕ Когда I Log.i("adapterPos", String.valueOf(adapter.adapterPos));
в onSwiped, он возвращает -1 даже до установки -1 ...
У меня есть recyclerView
, а также custom adapter
для отображения информации об упражнении.
приложение
Когда пользователь нажимает на элемент recyclerView, фон элементов становится зеленым, а кнопка сохранения превращается в кнопку обновления, так что пользователь может обновить свои существующие записанные упражнения.
У меня также есть метод onSwiped, который реализован внутри моего фрагмента. Когда пользователь проводит пальцем по элементу, он удаляется из базы данных.
Когда пользователь проводит пальцем, чтобы удалить элемент, я хотел бы вернуть фон для ВСЕХ элементов обратно на значение по умолчанию (серый).
Как это можно сделать?
Примечание: если выбран элемент 2 и пользователь решает провести элемент 1, даже после удаления элемента 1 элемент 2 все еще выбран .
