问题 I've been messing around with the new APIs in Android 5.0 and have been trying to figure out whether or not it is possible to animate both a ViewGroup and one of its children separately as shared elements during an Activity transition.

问题 I'm making a scene transition for devices with API level 20+. It is working fine, but I want to set custom duration to make the transition. Is it possible ??

问题 I'm experiencing a strange issue / bug regarding ImageView transitions between Activities in Android 5.0. I'm trying to transition a thumbnail image from Fragment A (in Activity A ) to the header image of Fragment B (in Activity B ). It works well most of the time, but it sometimes messes up ever so slightly. Here's a picture of what it looks like when it messes up: Naturally, it's supposed to fill the entire area. Both ImageViews are set to ScaleType.CENTER_CROP , so I can't imagine that

问题 I wanted to setup a shared element transition when going from one Activity to another. The first Activity has a RecyclerView with items. When an item is clicked that item should animate to the new activity. So i've set a android:transitionName="item" on both the final activity views, as wel as the recycler-view item views. I'm also using this code when going to the next activity: this.startActivity(intent, ActivityOptions.makeSceneTransitionAnimation(this, itemView, "boomrang_item").toBundle(

问题 I am doing some basic shared element activity transition animations with code similar to this: Intent i = new Intent(AnActivity.this, AnotherActivity.class); ActivityOptionsCompat options = ActivityOptionsCompat.makeSceneTransitionAnimation(this, Pair.create(vBackground, "background"), Pair.create(vImage, "image"), Pair.create(vName, "name"), Pair.create(vDistance, "distance") ); startActivity(i, options.toBundle()); Can I change the Z-order that the animation assigns to the views?

问题 In my app I have code like this: final FragmentTransaction transaction = getSupportFragmentManager().beginTransaction(); transaction.replace(R.id.fragment_container, fragment, "tag"); transaction.addSharedElement(view, "transitionName"); transaction.addToBackStack(null) .commit(); It works fine, shared elements animation works.

问题 I am trying my hands with SharedElements and Content Transitions in Android. I was trying to combine Content Transitions and Shared Elements and create a particular animation, however I have encountered a problem. After the transition on Shared Elements (ImageView) end, I am using content Transitions to animate Text View into position using Slide Transition.

问题 I see strange thing in my shared element transition on Lollipop. Shared elements are flickering just before they are starting to animate (please see video https://www.youtube.com/watch?v=DCoyyC_S-9A) I've no idea why it is happening.
