activity-transition

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. The screenshots below gives a simplified example of what I am trying to achieve: In the first activity, the dark gray box is a ViewGroup centered in the screen and the red box is its child View (the layout XML code I am using can be found here). When the user

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 On Android 5.0 Lollipop, I have two activities A and B. Activity B has a slie enter transition from bottom with a Overlay ActionBar, but when B shows, the ActionBar also slide from bottom to top. How can i prevent the actionbar from slide transition. does system actionbar has an id that i can add to the exclude target ? thanks! 回答1: If you are using the AppCompat v7 library, it is easy: View decor = getWindow().getDecorView(); int actionBarId = R.id.action_bar_container; enterTransition

问题 How can i keep an animation alive while the transitions between activities are occurring? Suppose that i have two activities A and B. Activity B has a "slide in" transition over the activity A. I want to keep a button rotating in my activity A while the transition of B is occurring. My button stop the rotating animation when the Activity B starts the slide over the activity A. I guess it happens because the android switch the UI Thread process to the new activity that is coming and stop what

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'm trying to make an Activity Transition using Shared Elements on a pre-Lollipop device (4.x). Is it possible? So far, I'm trying this: public class RewardDetail extends ActionBarActivity { @Override public void onCreate(final Bundle savedInstanceState) { ... ViewCompat.setTransitionName(imageView, TRANSITION_NAME); } ... public static void launch(ActionBarActivity activity, View transitionView, WelcomeReward detailData) { ActivityOptionsCompat options = ActivityOptionsCompat

问题 I'd like to use ActivityOptionsCompat.makeSceneTransitionAnimation to do a scene transition between 2 UI elements but I also need to start multiple activities. This code causes issues (prevents the second activity from even starting). I can start the activities individually to pass the options to the correct activity, but that has its own issues with a flickering UI. Is there another way to accomplish this? if (targetActivity == TargetActivity.HOMEPAGE) { baseActivity.startActivity(homeIntent

问题 I tried to make animations/transitions between activities but I couldn't make it perfect and good. And I couldn't find any helping guide. Can you tell me how to create an ActivityOptions tranistion, like this: http://3.bp.blogspot.com/-dadidlU3muU/VE6og4Ra_BI/AAAAAAAAA8E/uVCWrYMetGI/s400/herotransition.gif Step by step? Thanks. 回答1: You need two shared elements: The card (the entire card) from the list view will be shared and mapped to the root view of the detail view activity. You can
