chandruscm / activity_menu_app_bar_1.xml
Last active August 14, 2019 13:58
activity_menu_app_bar_1.xml produces the desired effect, but the toolbar moves up: as per the height set in the empty CollapsingToolbarLayout before adding the elevation. activity_menu_app_bar_2.xml does not work, it adds elevation by default without scrolling.
