NavigationDrawer появляется над основным видом деятельности, перекрывающим CollapsingToolbar. Это делает его странным. Я хочу, чтобы он появился ниже CollapsingToolbar, отображая название и кнопки действий. Также есть еще одна ошибка, которая заставляет меня сходить с ума, когда NavigationDrawer закрывает название, исчезает из панели действий. Теперь это происходит только тогда, когда CollapsingToolbar находится в сложенном состоянии. Пожалуйста, помогите мне на этом.Навигационный ящик перекрывает CollapsingToolbar
Основной файл деятельности является: -
