Transition blinks after changing orientation

Question

UPDATE

Ive discovered an error with Google https://issuetracker.google.com/issues/63663775

I am trying to use makeSceneTransitionAnimation in my current android application.

I have a Source Activity that contains a Fragment , and inside the Fragment there is a RecyclerView .

When I click on an image in RecyclerView I go to my Target Activity , which contains a fragment that correctly displays the image with acceptable animation.

Pressing the back button correctly changes the animation.

The above works great in both portrait and landscape orientations.

A problem with BLINKING occurs when I change the orientation when viewing the target fragment, and then click the "Back" button.

There are other problems, such as the image not returning directly to its original position, and on older devices I see horizontal lines, such as interference from a poorly tuned analog television.

Using it BLINKING is very bad, the screen of the device completely BLACK takes about 500 ms.

I downloaded and deployed the transition application for common google elements and added that it has the same “Feature”.

I tried several solutions and none of them worked, like this .

Below is the page where there is a problem.

Answer 1

Here's the problem: you run Activity2 in portrait mode and return to Activity1 in landscape mode. But since you performed a change in orientation, the hierarchy of the Activity1 view is destroyed and created, so there is no longer a View originally started with the transition.

What you can do is reprogram the view from the old to the new using the Activity#setExitSharedElementCallback() API. There is little work to be done to deal with this situation, although that I have already described step by step in this answer.

The best choice for you is to check the Alex Lockwood application on github with the necessary functionality, it will be much easier for you to understand how to cope with the situation.

 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); setExitSharedElementCallback(new SharedElementCallback() { @Override public void onMapSharedElements(List<String> names, Map<String, View> sharedElements) { if (we are coming back to Activity1) { View newSharedElement = findViewById(R.id.your_imageview); if (newSharedElement != null) { names.clear(); names.add("transition name"); sharedElements.clear(); sharedElements.put("transition name", newSharedElement); } } else { // we are leaving Activity1 } } }); } 

Basically, you clear the map and add a new pair of "transition name" to it. You can see how the if (we are coming back to Activity1) check is done here .

Here is a feature implemented in one of my applications .

Answer 2

I think the problem is with ImageView layouts, since the transition to the scene calculates the difference between the starting and ending positions, and then animates the difference, but here the final position was changed due to a change in orientation, you can try to recreate the final layout as soon. when you back off in case of a change in orientation, maybe I'm wrong, but I can only think about this scenario, can you provide the code for the same (it was too big to add as a comment, so you need to add in as an answer).

Answer 3

This seems to be happening only on Oreo. It can be played on API 26 emulator using the Google sample project, available here: https://github.com/googlesamples/android-ActivitySceneTransitionBasic/#readme

I was able to fix the problem in my application by adding the following:

 <item name="android:windowIsTranslucent">true</item> 

In the style of my activity.
