A TransitionPropagation
that propagates based on the distance to the side
and, orthogonally, the distance to epicenter. If the transitioning View is visible in
the start of the transition, then it will transition sooner when closer to the side and
later when farther. If the view is not visible in the start of the transition, then
it will transition later when closer to the side and sooner when farther from the edge.
This is the default TransitionPropagation used with Slide
.

getStartDelay
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 TransitionPropagation s
used in the Transition so that the smallest delay will be 0. Returned values may be
negative. |
setPropagationSpeed
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 at the side
set in setSide(int)
and View centered at the opposite edge 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. |
setSide
public void setSide (int side)
Sets the side that is used to calculate the transition propagation. If the transitioning
View is visible in the start of the transition, then it will transition sooner when
closer to the side and later when farther. If the view is not visible in the start of
the transition, then it will transition later when closer to the side and sooner when
farther from the edge. The default is Gravity.BOTTOM
.
Parameters | |
---|---|
side |
int : The side that is used to calculate the transition propagation. Must be one of
Gravity.LEFT , Gravity.TOP , Gravity.RIGHT ,
Gravity.BOTTOM , Gravity.START , or Gravity.END .
Value is Gravity.LEFT , Gravity.TOP , Gravity.RIGHT , Gravity.BOTTOM , Gravity.START , or Gravity.END |
