Я пытаюсь создать аналогичный макет для экрана профиля пользователя в своем приложении. Вот что мне нужно: 1. Кнопки «Назад», «Плюс» и «Изображение» должны быть на панели инструментов как в свернутом, так и в развернутом состоянии. 2. Панель инструментов должна быть прозрачной в развернутом состоянии и менять цвет содержимого экрана при сворачивании. 3. Текст Served(180) и Cooked(300) должен быть кликабельным и вести к другим действиям. 4. При сворачивании вкладка должна быть закреплена под панелью инструментов. 5. ViewPager, прикрепленный к вкладкам, должен работать нормально и содержит список.
Вот моя попытка:

Проблема: щелчок в любом месте содержимого панели инструментов «Сворачивание» (внутри относительного макета) в начале не вызывает никаких проблем, но как только я выполняю некоторую прокрутку (сворачивание панели инструментов, прокрутка содержимого окна просмотра, изменение вкладок) и снова возвращаюсь к сворачивающейся панели инструментов в расширенное состояние, и нажмите в любом месте на нем, приложение аварийно завершает работу. Я получаю следующую ошибку:

В чем причина такого поведения и как это исправить.
