# Fade
| This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings).

*** ** * ** ***
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. Visibility is determined by both the[setVisibility(int)](https://developer.android.com/reference/android/view/View.html#setVisibility(int))state of the view as well as whether it is parented in the current view hierarchy.
The ability of this transition to fade out a particular view, and the way that that fading operation takes place, is based on the situation of the view in the view hierarchy. For example, if a view was simply removed from its parent, then the view will be added into a[ViewGroupOverlay](https://developer.android.com/reference/android/view/ViewGroupOverlay.html)while fading. If a visible view is changed to be[GONE](https://developer.android.com/reference/android/view/View.html#GONE)or[INVISIBLE](https://developer.android.com/reference/android/view/View.html#INVISIBLE), then the visibility will be changed to[VISIBLE](https://developer.android.com/reference/android/view/View.html#VISIBLE)for the duration of the animation. However, if a view is in a hierarchy which is also altering its visibility, the situation can be more complicated. In general, if a view that is no longer in the hierarchy in the end scene still has a parent (so its parent hierarchy was removed, but it was not removed from its parent), then it will be left alone to avoid side-effects from improperly removing it from its parent. The only exception to this is if the previous[Scene](https://developer.android.com/reference/android/support/transition/Scene)was[created from a layout resource file](https://developer.android.com/reference/android/support/transition/Scene#getSceneForLayout(android.view.ViewGroup, int, android.content.Context)), then it is considered safe to un-parent the starting scene view in order to fade it out.
A Fade transition can be described in a resource file by using the tag`fade`, along with the standard attributes of`Fade`and[Transition](https://developer.android.com/reference/android/support/transition/Transition).

```
int IN
```
Fading mode used in[Fade(int)](https://developer.android.com/reference/android/support/transition/Fade#Fade(int))to make the transition operate on targets that are appearing. Maybe be combined with[OUT](https://developer.android.com/reference/android/support/transition/Fade#OUT)to fade both in and out.
Constant Value: 1 (0x00000001)
### OUT
added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
int OUT
```
Fading mode used in[Fade(int)](https://developer.android.com/reference/android/support/transition/Fade#Fade(int))to make the transition operate on targets that are disappearing. Maybe be combined with[IN](https://developer.android.com/reference/android/support/transition/Fade#IN)to fade both in and out.

## Public constructors
### Fade
added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
Fade (int fadingMode)
```
Constructs a Fade transition that will fade targets in and/or out, according to the value of fadingMode.
| Parameters ||
|--------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `fadingMode` | `int`: The behavior of this transition, a combination of[IN](https://developer.android.com/reference/android/support/transition/Fade#IN)and[OUT](https://developer.android.com/reference/android/support/transition/Fade#OUT).
|
### Fade

## Public methods
### captureStartValues
added in[version 25.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
void captureStartValues (TransitionValues transitionValues)
```
Captures the values in the start scene for the properties that this transition monitors. These values are then passed as the startValues structure in a later call to[createAnimator(ViewGroup, TransitionValues, TransitionValues)](https://developer.android.com/reference/android/support/transition/Transition#createAnimator(android.view.ViewGroup, android.support.transition.TransitionValues, android.support.transition.TransitionValues)). The main concern for an implementation is what the properties are that the transition cares about and what the values are for all of those properties. The start and end values will be compared later during the[createAnimator(ViewGroup, TransitionValues, TransitionValues)](https://developer.android.com/reference/android/support/transition/Transition#createAnimator(android.view.ViewGroup, android.support.transition.TransitionValues, android.support.transition.TransitionValues))method to determine what, if any, animations, should be run.
Subclasses must implement this method. The method should only be called by the transition system; it is not intended to be called from external classes.
| Parameters ||
|--------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `transitionValues` | `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.
|
### onAppear
added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
Animator onAppear (ViewGroup sceneRoot,
View view,
TransitionValues startValues,
TransitionValues endValues)
```
The default implementation of this method returns a null Animator. Subclasses should override this method to make targets appear with the desired transition. The method should only be called from[onAppear(ViewGroup, TransitionValues, int, TransitionValues, int)](https://developer.android.com/reference/android/support/transition/Visibility#onAppear(android.view.ViewGroup, android.support.transition.TransitionValues, int, android.support.transition.TransitionValues, int)).
| Parameters ||
|---------------|----------------------------------------------------------------------------------------------------------------|
| `sceneRoot` | `ViewGroup`: The root of the transition hierarchy
|
| `view` | `View`: The View to make appear. This will be in the target scene's View hierarchy and will be VISIBLE.
|
| `startValues` | `TransitionValues`: The target values in the start scene
|
| `endValues` | `TransitionValues`: The target values in the end scene
|
| Returns ||
|-------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------|
| [Animator](https://developer.android.com/reference/android/animation/Animator.html) | An Animator to be started at the appropriate time in the overall transition for this scene change. A null value means no animation should be run.
|
### onDisappear
added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions)
```
Animator onDisappear (ViewGroup sceneRoot,
View view,
TransitionValues startValues,
TransitionValues endValues)
```
The default implementation of this method returns a null Animator. Subclasses should override this method to make targets disappear with the desired transition. The method should only be called from[onDisappear(ViewGroup, TransitionValues, int, TransitionValues, int)](https://developer.android.com/reference/android/support/transition/Visibility#onDisappear(android.view.ViewGroup, android.support.transition.TransitionValues, int, android.support.transition.TransitionValues, int)).
| Parameters ||
|---------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `sceneRoot` | `ViewGroup`: The root of the transition hierarchy
|
| `view` | `View`: The View to make disappear. This will be in the target scene's View hierarchy or in an[ViewGroupOverlay](https://developer.android.com/reference/android/view/ViewGroupOverlay.html)and will be VISIBLE.
|
| `startValues` | `TransitionValues`: The target values in the start scene
|
| `endValues` | `TransitionValues`: The target values in the end scene
|
| Returns ||
|-------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------|
| [Animator](https://developer.android.com/reference/android/animation/Animator.html) | An Animator to be started at the appropriate time in the overall transition for this scene change. A null value means no animation should be run.
