RecyclerView. Оптимизация Adapter

Привет, Хабр! Меня зовут Михаил Богатиков, я Android-разработчик в ПСБ. В своей работе я часто сталкиваюсь с задачей отображения сложных и динамических списков. Казалось бы, RecyclerView — давно знакомый инструмент. Но когда данные становятся разнородными, а списки — большими, простой вызов notifyDataSetChanged() превращается в узкое место, вызывающее фризы и дергающуюся анимацию. Как перейти от лобового обновления к точечным изменениям? Как объединить несколько типов элементов в одном адаптере? В этой статье я пройду путь эволюции работы с RecyclerView.Adapter: - Разберу, как работает система уведомлений под капотом. - Вспомню, как DiffUtil и ListAdapter спасли нас от ручных вычислений. - Расскажу про AsyncListDiffer, ConcatAdapter и нюансы восстановления позиции. - И наконец, покажу, как спроектировать универсальный адаптер с поддержкой разных ViewHolder, частичным обновлением (Payloads) и ViewBinding — с полным примером кода. Поехали!

It's gotten so bad, that the only way you are certain, that your television will not squeal on you, is by making sure that you never ever ever let it go on the internet, because if you do it will just create a tunnel report to its Masters and if you close that tunnel it will just create others

Smart TV's and IOT devices have payloads just like malware!
