Kotlin |Java

abstract class VisibilityPropagation : TransitionPropagation

kotlin.Any
↳	android.transition.TransitionPropagation
	↳	android.transition.VisibilityPropagation

Known Direct Subclasses CircularPropagation, SidePropagation 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
VisibilityPropagation()

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.

Inherited functions
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

captureValues

Added in API level 21

open fun captureValues(values: TransitionValues!): Unit

Parameters

transitionValues

The holder for any values that the Transition wishes to store. Values are stored in the values field of this TransitionValues object and are keyed from a String value. For example, to store a view's rotation value, a transition might call transitionValues.values.put("appname:transitionname:rotation", view.getRotation()). The target view will already be stored in the transitionValues structure when this method is called.

getPropagationProperties

Added in API level 21

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

Return
Array<String!>!	An array of property names as described in the class documentation for TransitionValues.

getViewVisibility

Added in API level 21

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.

getViewX

Added in API level 21

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.

getViewY

Added in API level 21

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.
