Example 1 with SpringAnimationBuilder

use of com.android.launcher3.anim.SpringAnimationBuilder in project android_packages_apps_Launcher3 by crdroidandroid.

the class WorkspaceStateTransitionAnimation method getSpringScaleAnimator.

 * Returns a spring based animator for the scale property of {@param v}.

Example 2 with SpringAnimationBuilder
