TransitionValues

extends Object
java.lang.Object
   ↳ android.transition.TransitionValues

Class Overview

Data structure which holds cached values for the transition. The view field is the target which all of the values pertain to. The values field is a map which holds information for fields according to names selected by the transitions. These names should be unique to avoid clobbering values stored by other transitions, such as the convention project:transition_name:property_name. For example, the platform might store a property "alpha" in a transition "Fader" as "android:fader:alpha".

These values are cached during the captureStartValues(TransitionValues) capture} phases of a scene change, once when the start values are captured and again when the end values are captured. These start/end values are then passed into the transitions via the for createAnimator(ViewGroup, TransitionValues, TransitionValues) method.

Public Methods

public boolean equals (Object other)

Added in API level 19

Compares this instance with the specified object and indicates if they are equal. In order to be equal, o must represent the same object as this instance using a class-specific comparison. The general contract is that this comparison should be reflexive, symmetric, and transitive. Also, no object reference other than null is equal to null.

The default implementation returns true only if this == o. See Writing a correct equals method if you intend implementing your own equals method.

The general contract for the equals and hashCode() methods is that if equals returns true for any two objects, then hashCode() must return the same value for these objects. This means that subclasses of Object usually override either both methods or neither of them.

Parameters
other the object to compare this instance with.
Returns
  • true if the specified object is equal to this Object; false otherwise.

public int hashCode ()

Added in API level 19

Returns an integer hash code for this object. By contract, any two objects for which equals(Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Returns
  • this object's hash code.

public String toString ()

Added in API level 19

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression: 

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns
  • a printable representation of this object.
