abstract class Visibility : Transition

kotlin.Any
↳	androidx.transition.Transition
	↳	androidx.transition.Visibility

Known Direct Subclasses Explode, Fade, Slide Explode This transition tracks changes to the visibility of target views in the start and end scenes and moves views in or out from the edges of the scene. Fade This transition tracks changes to the visibility of target views in the start and end scenes and fades views in or out when they become visible or non-visible. Slide This transition tracks changes to the visibility of target views in the start and end scenes and moves views in or out from one of the edges of the scene.

This transition tracks changes to the visibility of target views in the start and end scenes. Visibility is determined not just by the View#setVisibility(int) state of views, but also whether views exist in the current view hierarchy. The class is intended to be a utility for subclasses such as Fade, which use this visibility information to determine the specific animations to run when visibility changes occur. Subclasses should implement one or both of the methods onAppear(ViewGroup, TransitionValues, int, TransitionValues, int), onDisappear(ViewGroup, TransitionValues, int, TransitionValues, int) or onAppear(ViewGroup, View, TransitionValues, TransitionValues), onDisappear(ViewGroup, View, TransitionValues, TransitionValues).

Summary

Constants
static Int	MODE_IN Mode used in setMode(int) to make the transition operate on targets that are appearing.
static Int	MODE_OUT Mode used in setMode(int) to make the transition operate on targets that are disappearing.

Inherited constants

From class Transition Int MATCH_ID With setMatchOrder(int...), chooses to match by android.view.View#getId(). Negative IDs will not be matched. Int MATCH_INSTANCE With setMatchOrder(int...), chooses to match by View instance. Int MATCH_ITEM_ID With setMatchOrder(int...), chooses to match by the android.widget.Adapter item id. When android.widget.Adapter#hasStableIds() returns false, no match will be made for items. Int MATCH_NAME With setMatchOrder(int...), chooses to match by android.view.View#getTransitionName(). Null names will not be matched.
