如何知道共享元素转换何时结束 [英] How to know when Shared Element Transition ends

问题描述

我正在两次活动之间使用Shared Element Transitions.过渡效果很好，但是我想知道共享元素过渡的结束时间，以便我可以展示其他内容.

I am working with Shared Element Transitions between activities. The transition is working fine but I want to know when the shared element transition ends so that I can show other things.

我尝试在要转换的活动中的SharedElementCallback中使用onSharedElementEnd，但是在转换开始之前会被调用.

I tried using onSharedElementEnd in SharedElementCallback in the activity I am transition to but that gets called before the transition starts.

我可以听另一个回调吗?

is there another callback i can listen for?

推荐答案

您是否尝试将动画侦听器绑定到onMapSharedElements内部的共享元素视图? ViewCompat.animate(view)将为您提供新的或缓存的ViewPropertyAnimator(Compat)，然后绑定动画侦听器应该很简单.不过，我还没有尝试过.

Did you try to bind animation listener to the shared element view inside onMapSharedElements? ViewCompat.animate(view) will give you either a new or cached ViewPropertyAnimator(Compat) and then binding the animation listener should be trivial. I haven't tried it, though.

setEnterSharedElementCallback(new SharedElementCallback() {
            @Override
            public void onMapSharedElements(List<String> names, Map<String, View> sharedElements) {
                super.onMapSharedElements(names, sharedElements);
                View keySharedElementView = sharedElements.get("keySharedElement");
                if(keySharedElementView != null){
                    ViewCompat.animate(keySharedElementView).setListener(new ViewPropertyAnimatorListenerAdapter(){
                        @Override
                        public void onAnimationEnd(View view) {
                            super.onAnimationEnd(view);
                        }
                    });
                }
            }
        });

如何在共享元素过渡中添加Transition.Listener?

What about adding Transition.Listener to the shared element transition?

 Transition sharedElementEnterTransition = getWindow().getSharedElementEnterTransition();
 sharedElementEnterTransition.addListener(new TransitionListenerAdapter() {
         @Override
          public void onTransitionEnd(android.support.transition.Transition transition) {
                    super.onTransitionEnd(transition);
           }
      });
