The activity_scrolling.xml is given below:Īpp:layout_anchor and app:layout_anchorGravity anchors the FAB to the bottom right of the AppBarLayout Android CollapsingToolbarLayout Example Project Structure

In this tutorial, we’ll be doing changes in the default project such as showing an ImageView, showing the toolbar equivalent icon from the FAB button, when it’s collapsed. Running the default new project should show an output like this: If you’ve updated to the latest SDK recently choose the Scrolling Activity type (it contains a ready-made implementation of CollapsingToolbarLayout) while creating a new project. This requires an integer value such as “100”. app:scrimAnimationDuration: Specifies the duration used for scrim visibility animations.app:contentScrim: This requires specifying a drawable or color value of the CollapsingToolbarLayouts content when it has been scrolled sufficiently off screen eg.app:collapsedTitleGravity: Specifies the gravity of title in the container when collapsed.app:layout_scrollFlags: The scroll flags of this layout is typically set to “scroll|exitUntilCollapsed”.

The text size becomes smaller as the layout is collapsed and scrolled off the screen.
