AutoTransition

AutoTransition Utility class for creating a default transition that automatically fades, moves, and resizes views during a scene change.

A TransitionSet is a parent of child transitions (including other TransitionSets). Using TransitionSets enables more complex choreography of transitions, where some sets play ORDERING_TOGETHER and others play ORDERING_SEQUENTIAL. For example, AutoTransition uses a TransitionSet to sequentially play a Fade(Fade.OUT), followed by a ChangeBounds, followed by a Fade(Fade.OUT) transition.

A TransitionSet can be described in a resource file by using the tag transitionSet, along with the standard attributes of R.styleable.TransitionSet and R.styleable.Transition. Child transitions of the TransitionSet object can be loaded by adding those child tags inside the enclosing transitionSet tag. For example, the following xml describes a TransitionSet that plays a Fade and then a ChangeBounds transition on the affected view targets:

     <transitionSet xmlns:android="http://schemas.android.com/apk/res/android"
             android:transitionOrdering="sequential">
         <fade/>
         <changeBounds/>
     </transitionSet>

Constants

ORDERING_SEQUENTIAL

Added in API level 19

public static final int ORDERING_SEQUENTIAL

A flag used to indicate that the child transitions of this set should play in sequence; when one child transition ends, the next child transition begins. Note that a transition does not end until all instances of it (which are playing on all applicable targets of the transition) end.

Constant Value: 1 (0x00000001)

ORDERING_TOGETHER

Added in API level 19

public static final int ORDERING_TOGETHER

A flag used to indicate that the child transitions of this set should all start at the same time.

Constant Value: 0 (0x00000000)

Public constructors

TransitionSet

Added in API level 19

public TransitionSet ()

Constructs an empty transition set. Add child transitions to the set by calling addTransition(android.transition.Transition) )}. By default, child transitions will play together.

TransitionSet

Added in API level 21

public TransitionSet (Context context, 
                AttributeSet attrs)

Parameters
`context`	`Context`
`attrs`	`AttributeSet`

Public methods

addListener

Added in API level 19

public TransitionSet addListener (Transition.TransitionListener listener)

Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.

Parameters
`listener`	`Transition.TransitionListener`: the listener to be added to the current set of listeners for this animation.

Returns
`TransitionSet`	This transition object.

addTarget

Added in API level 19

public TransitionSet addTarget (View target)

Sets the target view instances that this Transition is interested in animating. By default, there are no targets, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targets constrains the Transition to only listen for, and act on, these views. All other views will be ignored.

The target list is like the targetId list except this list specifies the actual View instances, not the ids of the views. This is an important distinction when scene changes involve view hierarchies which have been inflated separately; different views may share the same id but not actually be the same instance. If the transition should treat those views as the same, then addTarget(int) should be used instead of addTarget(android.view.View). If, on the other hand, scene changes involve changes all within the same view hierarchy, among views which do not necessarily have ids set on them, then the target list of views may be more convenient.

Parameters
`target`	`View`: A View on which the Transition will act, must be non-null.

Returns
`TransitionSet`	The Transition to which the target is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someView);`

addTarget

Added in API level 19

public TransitionSet addTarget (int targetId)

Adds the id of a target view that this Transition is interested in animating. By default, there are no targetIds, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetIds constrains the Transition to only listen for, and act on, views with these IDs. Views with different IDs, or no IDs whatsoever, will be ignored.

Note that using ids to specify targets implies that ids should be unique within the view hierarchy underneath the scene root.

Parameters
`targetId`	`int`: The id of a target view, must be a positive number.

Returns
`TransitionSet`	The Transition to which the targetId is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someId);`

addTarget

Added in API level 21

public TransitionSet addTarget (Class<T> targetType)

Adds the Class of a target view that this Transition is interested in animating. By default, there are no targetTypes, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetTypes constrains the Transition to only listen for, and act on, views with these classes. Views with different classes will be ignored.

Note that any View that can be cast to targetType will be included, so if targetType is View.class, all Views will be included.

Parameters
`targetType`	`Class`: The type to include when running this transition.

Returns
`TransitionSet`	The Transition to which the target class was added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(ImageView.class);`

addTarget

Added in API level 21

public TransitionSet addTarget (String targetName)

Adds the transitionName of a target view that this Transition is interested in animating. By default, there are no targetNames, and a Transition will listen for changes on every view in the hierarchy below the sceneRoot of the Scene being transitioned into. Setting targetNames constrains the Transition to only listen for, and act on, views with these transitionNames. Views with different transitionNames, or no transitionName whatsoever, will be ignored.

Note that transitionNames should be unique within the view hierarchy.

Parameters
`targetName`	`String`: The transitionName of a target view, must be non-null.

Returns
`TransitionSet`	The Transition to which the target transitionName is added. Returning the same object makes it easier to chain calls during construction, such as `transitionSet.addTransitions(new Fade()).addTarget(someName);`

addTransition

Added in API level 19

public TransitionSet addTransition (Transition transition)

Adds child transition to this set. The order in which this child transition is added relative to other child transitions that are added, in addition to the ordering property, determines the order in which the transitions are started.

If this transitionSet has a duration, interpolator, propagation delay, path motion, or epicenter callback set on it, the child transition will inherit the values that are set. Transitions are assumed to have a maximum of one transitionSet parent.

Parameters
`transition`	`Transition`: A non-null child transition to be added to this set.

Returns
`TransitionSet`	This transitionSet object.

captureEndValues

Added in API level 19

public void captureEndValues (TransitionValues transitionValues)

Captures the values in the end scene for the properties that this transition monitors. These values are then passed as the endValues structure in a later call to createAnimator(android.view.ViewGroup, android.transition.TransitionValues, android.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(android.view.ViewGroup, android.transition.TransitionValues, android.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

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.

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.

captureStartValues

Added in API level 19

public 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(android.view.ViewGroup, android.transition.TransitionValues, android.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(android.view.ViewGroup, android.transition.TransitionValues, android.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

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.

transitionValues

transitionValues.values.put("appname:transitionname:rotation",
 view.getRotation())

. The target view will already be stored in the transitionValues structure when this method is called.

clone

Added in API level 19

public TransitionSet clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Returns
`TransitionSet`	a clone of this instance.

excludeTarget

Added in API level 19

public Transition excludeTarget (View target, 
                boolean exclude)

Whether to add the given target to the list of targets to exclude from this transition. The exclude parameter specifies whether the target should be added to or removed from the excluded list.

Excluding targets is a general mechanism for allowing transitions to run on a view hierarchy while skipping target views that should not be part of the transition. For example, you may want to avoid animating children of a specific ListView or Spinner. Views can be excluded either by their id, or by their instance reference, or by the Class of that view (eg, Spinner).

Parameters
`target`	`View`: The target to ignore when running this transition.
`exclude`	`boolean`: Whether to add the target to or remove the target from the current list of excluded targets.

Returns
`Transition`	This transition object.

Excluding targets is a general mechanism for allowing transitions to run on a view hierarchy while skipping target views that should not be part of the transition. For example, you may want to avoid animating children of a specific ListView or Spinner. Views can be excluded by their id, their instance reference, their transitionName, or by the Class of that view (eg, Spinner).

Parameters
`targetName`	`String`: The name of a target to ignore when running this transition.

Returns
`TransitionSet`	This transitionSet object.

setEpicenterCallback

Added in API level 21

public void setEpicenterCallback (Transition.EpicenterCallback epicenterCallback)

Sets the callback to use to find the epicenter of a Transition. A null value indicates that there is no epicenter in the Transition and onGetEpicenter() will return null. Transitions like Explode use a point or Rect to orient the direction of travel. This is called the epicenter of the Transition and is typically centered on a touched View. The Transition.EpicenterCallback allows a Transition to dynamically retrieve the epicenter during a Transition.

Returns
`TransitionSet`	This transitionSet object.

setPathMotion

Added in API level 21

public void setPathMotion (PathMotion pathMotion)

Sets the algorithm used to calculate two-dimensional interpolation.

Transitions such as ChangeBounds move Views, typically in a straight path between the start and end positions. Applications that desire to have these motions move in a curve can change how Views interpolate in two dimensions by extending PathMotion and implementing PathMotion.getPath(float, float, float, float).

When describing in XML, use a nested XML tag for the path motion. It can be one of the built-in tags arcMotion or patternPathMotion or it can be a custom PathMotion using pathMotion with the class attributed with the fully-described class name. For example:

 <changeBounds>
     <pathMotion class="my.app.transition.MyPathMotion"/>
 </changeBounds>

 </changeBounds>

Parameters
`pathMotion`	`PathMotion`: Algorithm object to use for determining how to interpolate in two dimensions. If null, a straight-path algorithm will be used.

setPropagation

Added in API level 21

public void setPropagation (TransitionPropagation propagation)

Sets the method for determining Animator start delays. When a Transition affects several Views like Explode or Slide, there may be a desire to have a "wave-front" effect such that the Animator start delay depends on position of the View. The TransitionPropagation specifies how the start delays are calculated.

Parameters
`propagation`	`TransitionPropagation`: The class used to determine the start delay of Animators created by this Transition. A null value indicates that no delay should be used.

setStartDelay

Added in API level 19

public TransitionSet setStartDelay (long startDelay)

Sets the startDelay of this transition. By default, there is no delay (indicated by a negative number), which means that the Animator created by the transition will have its own specified startDelay. If the delay of a Transition is set, that delay will override the Animator delay.

Parameters
`startDelay`	`long`: The length of the delay, in milliseconds.

Returns
`TransitionSet`	This transition object.
