Android Interpolator Sample

This sample demonstrates the use of animation interpolators and path animations for Material Design.


Material design is a comprehensive guide for visual, motion, and interaction design across platforms and devices. Starting with API level 21, Android includes support for material design apps.

This sample demonstrates the use of Material Design animation interpolators and path animations. It uses an ObjectAnimator to animate two view properties, Scale_X and Scale_Y. Users can pick from a set of interpolator options. They can also define the duration of the animation.


  • Android SDK 27
  • Android Build Tools v27.0.2
  • Android Support Repository
