What it is
This is a reference project that explains and demonstrates Android's Transition Framework, the system for animating screens and views. It shows three things: animating content when moving between activities (Explode, Slide, Fade), animating shared elements such as a shared icon between two screens, and animating view changes within one activity. Each concept comes with short Java and XML code examples and screenshots.
- Add a Slide exit transition and a Fade enter transition between two Android activities
- Define transitions in XML under res/transition or in Java code
- Animate a shared icon growing from one screen into another using transitionName and ActivityOptions.makeSceneTransitionAnimation()
- Define a different return transition so going back uses a different animation than going forward
Great for
- Android developers learning activity transitions
- Developers who want copy-able examples of Explode, Slide, and Fade
- Developers working on shared element animations between activities
- Students following an introduction to Android UI animation
Not ideal for
- Anyone needing the latest Android animation APIs, because the README says the project is unmaintained and may not include newer features
- Non-Android developers, because the examples are specific to the Android framework and Java
How to get it
- 1
Clone and build from source
You'll need: Android Studio · Java
Clone the repository
git clone https://github.com/lgvalle/Material-Animations - 2
Run it
- Clone the repository and open it in Android Studio
- Open the MainActivity and the transition examples to see the code
- Run the app on an Android device or emulator
- Tap the sample elements to see each transition in action
- 3
Get the most out of it
- Read the step-by-step section on Enter, Exit, Return, and Reenter transitions before copying code
- Compare the XML and programmatic versions of the same transition to see how they map
- Use the shared element section as a template by giving both views the same android:transitionName
- Check the README's Android Arsenal link for related resources, while keeping in mind the project is no longer updated
Downloads
Strengths
- Clear, step-by-step explanations of how enter, exit, return, and reenter transitions relate
- Shows both XML and programmatic ways to define the same transition
- Includes screenshots and examples for each concept
Trade-offs
- The README states the project is unmaintained, with no further updates planned
- The last push was in April 2019, so the examples may not reflect current Android versions or APIs
- The README is truncated and the fragment section is incomplete in what was provided
