CircularPropagation


public class CircularPropagation
extends VisibilityPropagation

java.lang.Object
   ↳ android.transition.TransitionPropagation
     ↳ android.transition.VisibilityPropagation
       ↳ android.transition.CircularPropagation


A propagation that varies with the distance to the epicenter of the Transition or center of the scene if no epicenter exists. When a View is visible in the start of the transition, Views farther from the epicenter will transition sooner than Views closer to the epicenter. When a View is not in the start of the transition or is not visible at the start of the transition, it will transition sooner when closer to the epicenter and later when farther from the epicenter. This is the default TransitionPropagation used with Explode.

Summary

Public constructors

CircularPropagation()

Public methods

long getStartDelay(ViewGroup sceneRoot, Transition transition, TransitionValues startValues, TransitionValues endValues)

Called by Transition to alter the Animator start delay.

void setPropagationSpeed(float propagationSpeed)

Sets the speed at which transition propagation happens, relative to the duration of the Transition.

Inherited methods

void captureValues(TransitionValues values)

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

String[] getPropagationProperties()

Returns the set of property names stored in the TransitionValues object passed into captureValues(android.transition.TransitionValues) that this transition propagation cares about for the purposes of preventing duplicate capturing of property values.

int getViewVisibility(TransitionValues values)

Returns View.getVisibility() for the View at the time the values were captured.

int getViewX(TransitionValues values)

Returns the View's center x coordinate, relative to the screen, at the time the values were captured.

int getViewY(TransitionValues values)

Returns the View's center y coordinate, relative to the screen, at the time the values were captured.

abstract void captureValues(TransitionValues transitionValues)

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

abstract String[] getPropagationProperties()

Returns the set of property names stored in the TransitionValues object passed into captureValues(android.transition.TransitionValues) that this transition propagation cares about for the purposes of preventing duplicate capturing of property values.

abstract long getStartDelay(ViewGroup sceneRoot, Transition transition, TransitionValues startValues, TransitionValues endValues)

Called by Transition to alter the Animator start delay.

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

getStartDelay

Added in API level 21
public long getStartDelay (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.

Parameters
sceneRoot ViewGroup: The root of the View hierarchy running the transition.

transition Transition: The transition that created the Animator

startValues TransitionValues: The values for a specific target in the start scene.

endValues TransitionValues: The values for the target in the end scene.

Returns
long 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.

setPropagationSpeed

Added in API level 21
public void setPropagationSpeed (float propagationSpeed)

Sets the speed at which transition propagation happens, relative to the duration of the Transition. A propagationSpeed of 1 means that a View centered farthest from the epicenter and View centered at the epicenter will have a difference in start delay of approximately the duration of the Transition. A speed of 2 means the start delay difference will be approximately half of the duration of the transition. A value of 0 is illegal, but negative values will invert the propagation.

Parameters
propagationSpeed float: The speed at which propagation occurs, relative to the duration of the transition. A speed of 4 means it works 4 times as fast as the duration of the transition. May not be 0.
