public class Slide
extends Visibility

java.lang.Object
↳	android.transition.Transition
	↳	android.transition.Visibility
		↳	android.transition.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. Visibility is determined by both the View.setVisibility(int) state of the view as well as whether it is parented in the current view hierarchy. Disappearing Views are limited as described in Visibility.onDisappear(android.view.ViewGroup, TransitionValues, int, TransitionValues, int).

Public methods

captureEndValues

Added in API level 21

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

public void captureStartValues (TransitionValues transitionValues)

Captures the values in the start scene for the properties that this transition monitors.

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.
