CollapsingToolbarLayout

CollapsingToolbarLayout is a wrapper for Toolbar which implements a collapsing app bar. It is designed to be used as a direct child of a AppBarLayout. CollapsingToolbarLayout contains the following features:

Collapsing title

A title which is larger when the layout is fully visible but collapses and becomes smaller as the layout is scrolled off screen. You can set the title to display via setTitle(CharSequence). The title appearance can be tweaked via the collapsedTextAppearance and expandedTextAppearance attributes.

Content scrim

A full-bleed scrim which is show or hidden when the scroll position has hit a certain threshold. You can change this via setContentScrim(Drawable).

Status bar scrim

A scrim which is shown or hidden behind the status bar when the scroll position has hit a certain threshold. You can change this via setStatusBarScrim(Drawable). This only works on LOLLIPOP devices when we set to fit system windows.

Parallax scrolling children

Child views can opt to be scrolled within this layout in a parallax fashion. See CollapsingToolbarLayout.LayoutParams.COLLAPSE_MODE_PARALLAX and CollapsingToolbarLayout.LayoutParams.setParallaxMultiplier(float).

Pinned position children

Child views can opt to be pinned in space globally. This is useful when implementing a collapsing as it allows the Toolbar to be fixed in place even though this layout is moving. See CollapsingToolbarLayout.LayoutParams.COLLAPSE_MODE_PIN.

Do not manually add views to the Toolbar at run time. We will add a 'dummy view' to the Toolbar which allows us to work out the available space for the title. This can interfere with any views which you add.

For more information, see the component developer guidance and design guidelines.
