Interfaces

DynamicAnimation.OnAnimationEndListener	An animation listener that receives end notifications from an animation.
DynamicAnimation.OnAnimationUpdateListener	Implementors of this interface can add themselves as update listeners to an DynamicAnimation instance to receive callbacks on every animation frame, after the current frame's values have been calculated for that DynamicAnimation.

Classes

DynamicAnimation	This class is the base class of physics-based animations.
DynamicAnimation.ViewProperty	ViewProperty holds the access of a property of a View.
FlingAnimation	Fling animation is an animation that continues an initial momentum (most often from gesture velocity) and gradually slows down.
FloatPropertyCompat	FloatPropertyCompat is an abstraction that can be used to represent a mutable float value that is held in a host object.
FloatValueHolder	FloatValueHolder holds a float value.
SpringAnimation	SpringAnimation is an animation that is driven by a SpringForce.
SpringForce	Spring Force defines the characteristics of the spring being used in the animation.

Top-level functions summary

FlingAnimation	flingAnimationOf(setter: (Float) -> Unit, getter: () -> Float) Creates FlingAnimation for a property that can be accessed via the provided setter and getter.
SpringAnimation	springAnimationOf(     setter: (Float) -> Unit,     getter: () -> Float,     finalPosition: Float ) Creates SpringAnimation for a property that can be accessed via the provided setter and getter.

Extension functions summary

inline SpringAnimation

SpringAnimation.withSpringForceProperties(func: SpringForce.() -> Unit) Updates or applies spring force properties like SpringForce.mDampingRatio, SpringForce.mFinalPosition and stiffness on SpringAnimation.

Top-level functions

flingAnimationOf

Artifact: androidx.dynamicanimation:dynamicanimation-ktx

View Source

Added in 1.0.0-alpha04

fun flingAnimationOf(setter: (Float) -> Unit, getter: () -> Float): FlingAnimation

Creates FlingAnimation for a property that can be accessed via the provided setter and getter. For example, the following sample code creates a FlingAnimation for the alpha property of a View object named view: flingAnimationOf(view::setAlpha, view::getAlpha)

Parameters
setter: (Float) -> Unit	The function that mutates the property being animated
getter: () -> Float	The function that returns the value of the property

Returns
FlingAnimation	FlingAnimation

springAnimationOf

Artifact: androidx.dynamicanimation:dynamicanimation-ktx

View Source

Added in 1.0.0-alpha04

fun springAnimationOf(
    setter: (Float) -> Unit,
    getter: () -> Float,
    finalPosition: Float = Float.NaN
): SpringAnimation

Creates SpringAnimation for a property that can be accessed via the provided setter and getter. If finalPosition is not Float.NaN then create SpringAnimation with SpringForce.mFinalPosition.

Parameters
setter: (Float) -> Unit	The function that mutates the property being animated
getter: () -> Float	The function that returns the value of the property
finalPosition: Float = Float.NaN	SpringForce.mFinalPosition Final position of spring.

Returns
SpringAnimation	SpringAnimation

Extension functions

withSpringForceProperties

Artifact: androidx.dynamicanimation:dynamicanimation-ktx

View Source

Added in 1.0.0-alpha04

inline fun SpringAnimation.withSpringForceProperties(func: SpringForce.() -> Unit): SpringAnimation

Updates or applies spring force properties like SpringForce.mDampingRatio, SpringForce.mFinalPosition and stiffness on SpringAnimation.

If SpringAnimation.mSpring is null in case SpringAnimation is created without final position it will be created and attached to SpringAnimation

Parameters
func: SpringForce.() -> Unit	lambda with receiver on SpringForce

Returns
SpringAnimation	SpringAnimation
