This transition tracks changes to the visibility of target views in the
start and end scenes and moves views in or out from the edges of the
scene. Visibility is determined by both the
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 onDisappear(android.view.ViewGroup, TransitionValues, int, TransitionValues, int)
.
Views move away from the focal View or the center of the Scene if no epicenter was provided.

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(ViewGroup, 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
createAnimator(android.view.ViewGroup, TransitionValues, 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.
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. |
