FAB не виден с CoordinatorLayout

Question

FAB не виден с CoordinatorLayout

Я не знаю почему, он работал раньше, но теперь мой FAB не виден в моем приложении. Я использовал пример галереи для создания этого действия (scrollingActivity), но я изменил NestedScrollView на LinearLayout. Я не знаю, если это причина.

Теперь я просто хочу, чтобы мой FAB был на виду, но я не знаю, как это сделать.

Также (не важно, но я хочу знать) это название деятельности называется Arrets, когда я смотрю в AndroidStudioDesigner, я обнаружил "Ligne" в заголовке панели инструментов Activity_arret.xml (почему? Я не знаю...), но "Arrets" в content_arret.xml. Где этот "Линь"? Я искал в манифесте и в папке res, но я не нахожу. Это не важно, но я просто хочу знать, откуда эта строка.

Потому что вы не можете добавить Fab-макет в layout_arret.

добавьте нижнюю строку в layout_arret.

<include layout="@layout/fab_layout"/>  // here define your actionbar or fab layout.
