CollapsingToolbarLayout is a wrapper for Toolbar that provides several visual effects that are bind to the content scroll events.

CollapsingToolbarLayout is a ViewGroup that serves as a wrapper for Toolbar providing several visual effects to it. The class is part of the library.

The effects provided by the class include

  • Collapsing title
  • Content scrim
  • Status bar scrim
  • Parallax scrolling children
  • Pinned position children

For the correct behavior the CollapsingToolbarLayout has to be direct child of AppBarLayout placed within a CoordinatorLayout that contains a vertically scrollable View with app:layout_behavior parameter specified. The effects are bind to the vertical scrolling of this View.

For more information visit class reference or the Android developers blog.
