В следующем приложении у вас есть в основном 2 фрагмента: 1) база данных продуктов питания, 2) список потребляемых продуктов питания
1) пользователь может вручную добавлять продукты с соответствующей информацией о питательных микроэлементах (ккал, углеводы, белок, et c.). Данные хранятся в базе данных SQL через Room и отслеживаются с помощью LiveData
2) фрагмента (FoodDiaryFragment.kt), который показывает «потребленную» пищу с помощью recyclerView. Пользователь может добавлять продукты, нажимая FAB, который отправляет пользователя к другому фрагменту (AddConsumedFoodFragment.kt). это показывает счетчик и форму. Вращатель показывает список продуктов из базы данных продуктов (из 1). В форме пользователь может просто ввести одно значение (сколько граммов выбранной пищи было потреблено). Эти данные также добавляются в ту же базу данных SQL в таблице с: id (автоматически сгенерированным), количеством (введенным пользователем), потребляемым продуктом питания (выбранным из счетчика и подключенным к другой таблице через внешний ключ) и потребляемой датой ( автоматически сгенерированная дата в момент добавления элемента).
Представление переработчика (2) показывает элементы с дополнительной информацией, которая рассчитывается в RecyclerViewAdapter (в основном, умножая количество и соответствующую информацию о питательных микроэлементах [ккал, углеводы) , et c.], см. getDailyValues () в адаптере), а также «группирует» элементы по дате. Это означает, что для каждого дня в представление recyclerView добавляется отдельный viewHolder (DateViewHolder), который отображает день (и сумму каждого макроса) (см. SortAndGroupFood () в FoodDiaryFragment.kt)
Поскольку я использую RecyclerView Selection, setStableIds () (см. Блок init) имеет значение true. StableIdKeyProvider. java добавляет объект ChildAttachStateChangeListener с функцией onChilViewDetachedFrom Windows ().
Я не уверен точно, когда вызывается эта функция (я хотел бы получить объяснение), но иногда это происходит, когда либо Элемент удален (элементы могут быть удалены через RecyclerView.Selection) или элемент добавлен. Приложение вылетает с показанным ниже исключением NullPointerException. Когда приложение перезапускается, действие, которое в конечном итоге закончилось в cra sh, было успешно выполнено.
Я действительно в отчаянии и пытался выяснить, почему нулевое представление передается этой функции в течение нескольких часов , но, очевидно, я не добился успеха.
В соответствии с docs findConistingViewHolder возвращает ноль, если предоставленное представление не является потомком этого RecyclerView
Вопрос: Какие проблемы вызывает возвращение нуля и как я могу превратить его? GitHub Depo Link
