open class CircularPropagation : VisibilityPropagation

kotlin.Any
↳	androidx.transition.TransitionPropagation
	↳	androidx.transition.VisibilityPropagation
		↳	androidx.transition.CircularPropagation

A propagation that varies with the distance to the epicenter of the Transition or center of the scene if no epicenter exists. When a View is visible in the start of the transition, Views farther from the epicenter will transition sooner than Views closer to the epicenter. When a View is not in the start of the transition or is not visible at the start of the transition, it will transition sooner when closer to the epicenter and later when farther from the epicenter. This is the default TransitionPropagation used with Explode.

Summary

Public constructors
`<init>()` A propagation that varies with the distance to the epicenter of the Transition or center of the scene if no epicenter exists.

Public methods
open Long	`getStartDelay(sceneRoot: ViewGroup!, transition: Transition!, startValues: TransitionValues!, endValues: TransitionValues!)`
open Unit	`setPropagationSpeed(propagationSpeed: Float)` Sets the speed at which transition propagation happens, relative to the duration of the Transition.

Inherited functions

From class VisibilityPropagation

`Unit`	`captureValues(values: TransitionValues!)`
`Array<String!>!`	`getPropagationProperties()`
`Int`	`getViewVisibility(values: TransitionValues!)` Returns `android.view.View#getVisibility()` for the View at the time the values were captured.
`Int`	`getViewX(values: TransitionValues!)` Returns the View's center x coordinate, relative to the screen, at the time the values were captured.
`Int`	`getViewY(values: TransitionValues!)` Returns the View's center y coordinate, relative to the screen, at the time the values were captured.

From class TransitionPropagation

Long

getStartDelay(sceneRoot: ViewGroup!, transition: Transition!, startValues: TransitionValues!, endValues: TransitionValues!)

Called by Transition to alter the Animator start delay. All start delays will be adjusted such that the minimum becomes zero.

Public methods

getStartDelay

open fun getStartDelay(
    sceneRoot: ViewGroup!, 
    transition: Transition!, 
    startValues: TransitionValues!, 
    endValues: TransitionValues!
): Long

setPropagationSpeed

open fun setPropagationSpeed(propagationSpeed: Float): Unit

Sets the speed at which transition propagation happens, relative to the duration of the Transition. A propagationSpeed of 1 means that a View centered farthest from the epicenter and View centered at the epicenter will have a difference in start delay of approximately the duration of the Transition. A speed of 2 means the start delay difference will be approximately half of the duration of the transition. A value of 0 is illegal, but negative values will invert the propagation.

Parameters
`propagationSpeed`	Float: The speed at which propagation occurs, relative to the duration of the transition. A speed of 4 means it works 4 times as fast as the duration of the transition. May not be 0.
