A transition animation – defining scenes and applying a transition


The Android Transition Framework offers the following:

  • Group-level animations: Animation applies to all views in a hierarchy
  • Transition-based animation: Animation based on starting and ending property change
  • Built-in animations: Some common transition effects, such as fade-in/out and movement
  • Resource file support: Save animation values to a resource (XML) file to load during runtime
  • Lifecycle callbacks: Receive callback notifications during the animation

A transition animation consists of the following:

  • Starting Scene: The view (or ViewGroup) at the start of the animation
  • Transition: The change type (see later on)
  • Ending Scene: The ending view (or ViewGroup)
  • Transitions: Android provides built-in support for the following three transitions:
    • AutoTransition (default transition): Fade out, move, resize, then fade in (in that order)
    • Fade: Fade in, fade out (default), or both (specify order)
    • ChangeBounds: Move and resize
