VisibilityPropagation

Kotlin |Java

abstract class VisibilityPropagation : TransitionPropagation

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

Known Direct Subclasses

CircularPropagation	A propagation that varies with the distance to the epicenter of the Transition or center of the scene if no epicenter exists.
SidePropagation	A `TransitionPropagation` that propagates based on the distance to the side and, orthogonally, the distance to epicenter.

Base class for TransitionPropagations that care about View Visibility and the center position of the View.

Summary

Public constructors
`<init>()` Base class for `TransitionPropagation`s that care about View Visibility and the center position of the View.

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

VisibilityPropagation()

Base class for TransitionPropagations that care about View Visibility and the center position of the View.

open fun captureValues(values: TransitionValues!): Unit

open fun getPropagationProperties(): Array<String!>!

open fun getViewVisibility(values: TransitionValues!): Int

Returns android.view.View#getVisibility() for the View at the time the values were captured.

Parameters
`values`	TransitionValues!: The TransitionValues captured at the start or end of the Transition.

Return
Int: `android.view.View#getVisibility()` for the View at the time the values were captured.

open fun getViewX(values: TransitionValues!): Int

Returns the View's center x coordinate, relative to the screen, at the time the values were captured.

Parameters
`values`	TransitionValues!: The TransitionValues captured at the start or end of the Transition.

Return
Int: the View's center x coordinate, relative to the screen, at the time the values were captured.

open fun getViewY(values: TransitionValues!): Int

Returns the View's center y coordinate, relative to the screen, at the time the values were captured.

Parameters
`values`	TransitionValues!: The TransitionValues captured at the start or end of the Transition.

Return
Int: the View's center y coordinate, relative to the screen, at the time the values were captured.
