问题 I am trying to use a ConstraintLayout in conjunction with views that slide up and down with animation. These views are organized vertically, with a RecyclerView at the top and two other views stacked under it: <constraint layout container> [ ] [ recycler view ] [ ] [48dp height 1st view] [48dp height 2nd view] </constraint layout container> The animation is very simple: When a button is tapped the 1st view moves from the bottom of the container to the position you can see above, when tapped

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. But if I change this code like getSupportFragmentManager().beginTransaction() .add(R.id.fragment_container, fragment, "tag") .hide(fragment) .commit(); final

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 am using the new KitKat Transitions API on Android. I have created two Scene objects using two layouts. I animate from Scene 1 to Scene 2 inside a Fragment . I want to automatically move back to the previous Scene when the user presses the back button. Is there some kind of built-in backstack mechanism when using Transitions , or do I have to roll my own? It is easy enough to call TransitionManager.go(scene1) , but I really do not want to implement an onBackPressed() listener in all my

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. However when I add <item name="android:windowSharedElementsUseOverlay">false</item> to my theme I don't see flickering but the transition is not looking good (they look like only half of it is animating second half of animation 'hidden'). Other transition

问题 I am writing an Android app where I want the activity to appear by animating in from the bottom of the screen to the top. I am able to do this with code from here: How to translate the activity from top to bottom and viceversa? However, I am not able to do the vice-versa animation wherein the Activity would disappear by sliding from the top to the bottom of the screen. I used the code in the above link; the activity appears by sliding up, but when disappearing, it fades out, instead of
