此转换跟踪对开始和结束场景中目标视图的可见性的更改,并将视图从场景的边缘移入或移出。 可见性由视图的setVisibility(int)
状态以及它是否在当前视图层次结构中确定。 消失视图受到限制,如onDisappear(android.view.ViewGroup, TransitionValues, int, TransitionValues, int)
。
如果没有提供震中,视图将从焦点视图或场景中心移开。

void captureEndValues (TransitionValues transitionValues)
在结束场景中捕获此转换监视的属性的值。 然后这些值作为endValues结构传递给createAnimator(ViewGroup, TransitionValues, TransitionValues)
。 实施的主要关注点是过渡期关注的属性以及所有这些属性的价值。 开始和结束值将在createAnimator(android.view.ViewGroup, TransitionValues, TransitionValues)
方法后期进行比较,以确定应该运行哪些动画(如果有的话)。
子类必须实现此方法。 该方法只能由过渡系统调用; 它不打算从外部类中调用。
Parameters | |
---|---|
transitionValues |
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. |
void captureStartValues (TransitionValues transitionValues)
捕获此转场监视的属性在开始场景中的值。 这些值然后在以后调用createAnimator(ViewGroup, TransitionValues, TransitionValues)
作为startValues结构createAnimator(ViewGroup, TransitionValues, TransitionValues)
。 实施的主要关注点是过渡期关注的属性以及所有这些属性的价值。 开始和结束值将在createAnimator(android.view.ViewGroup, TransitionValues, TransitionValues)
方法后期进行比较,以确定应该运行哪些动画(如果有的话)。

Parameters | |
---|---|
transitionValues |
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. |
Animator onAppear (ViewGroup sceneRoot, View view, TransitionValues startValues, TransitionValues endValues)
此方法的默认实现将返回空Animator。 子类应该重写此方法以使目标显示所需的转换。 该方法只能从onAppear(ViewGroup, TransitionValues, int, TransitionValues, int)
。
Parameters | |
---|---|
sceneRoot |
ViewGroup : The root of the transition hierarchy |
view |
View : The View to make appear. This will be in the target scene's View hierarchy and will be VISIBLE. |
startValues |
TransitionValues : The target values in the start scene |
endValues |
TransitionValues : The target values in the end scene |
Returns | |
---|---|
Animator |
An Animator to be started at the appropriate time in the overall transition for this scene change. A null value means no animation should be run. |
Animator onDisappear (ViewGroup sceneRoot, View view, TransitionValues startValues, TransitionValues endValues)
此方法的默认实现将返回空Animator。 子类应该重写此方法,使目标消失与所需的转换。 该方法只能从onDisappear(ViewGroup, TransitionValues, int, TransitionValues, int)
。
Parameters | |
---|---|
sceneRoot |
ViewGroup : The root of the transition hierarchy |
view |
View : The View to make disappear. This will be in the target scene's View hierarchy or in an ViewGroupOverlay and will be VISIBLE. |
startValues |
TransitionValues : The target values in the start scene |
endValues |
TransitionValues : The target values in the end scene |
Returns | |
---|---|
Animator |
An Animator to be started at the appropriate time in the overall transition for this scene change. A null value means no animation should be run. |
