Fields Summary

Constructors Summary

Methods Summary
public abstract void	captureValues(TransitionValues transitionValues) Captures the values in the start or end scene for the properties that this transition propagation monitors. These values are then passed as the startValues or endValues structure in a later call to {@link #getStartDelay(ViewGroup, Transition, TransitionValues, 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 {@link #getStartDelay(ViewGroup, Transition, TransitionValues, TransitionValues)}. method to determine the start delay. 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. param 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.
public abstract java.lang.String[]	getPropagationProperties() Returns the set of property names stored in the {@link TransitionValues} object passed into {@link #captureValues(TransitionValues)} that this transition propagation cares about for the purposes of preventing duplicate capturing of property values. A TransitionPropagation must override this method to prevent duplicate capturing of values and must contain at least one return An array of property names as described in the class documentation for {@link TransitionValues}.
public abstract long	getStartDelay(android.view.ViewGroup sceneRoot, Transition transition, TransitionValues startValues, TransitionValues endValues) Called by Transition to alter the Animator start delay. All start delays will be adjusted such that the minimum becomes zero. param sceneRoot The root of the View hierarchy running the transition. param transition The transition that created the Animator param startValues The values for a specific target in the start scene. param endValues The values for the target in the end scene. return A start delay to use with the Animator created by transition. The delay will be offset by the minimum delay of all TransitionPropagations used in the Transition so that the smallest delay will be 0. Returned values may be negative.
