From 187f16ddc66493c3046ceffed69e21c646dfa7b1 Mon Sep 17 00:00:00 2001 From: Graham Mendick Date: Mon, 19 Jun 2023 11:13:48 -0700 Subject: [PATCH] Support Android Transitions during Fragment navigation (#37857) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Summary: Adds support for Android Transitions during Fragment navigation. React Native navigation libraries (like [the Navigation router](https://github.com/grahammendick/navigation/blob/e9deae985a1962db17d6b1fbf90628d20c29810c/NavigationReactNative/src/android/src/main/java/com/navigation/reactnative/NavigationStackView.java#L139) and [React Native Screens](https://github.com/software-mansion/react-native-screens/blob/ea240b46866d66398904d0c2d0fe5fabdc2f269b/android/src/main/java/com/swmansion/rnscreens/ScreenContainer.kt#L98)) use Fragments to manage the stack of screens. But they can’t use Transitions to animate these Fragments because React Native images disappear during the Transition (see the videos in the Test Plan section below). Navigation libraries are forced to [setCustomAnimations](https://developer.android.com/reference/androidx/fragment/app/FragmentTransaction.html#setCustomAnimations(int,int)) instead of [enter and exit Transitions](https://developer.android.com/reference/android/app/Fragment#setEnterTransition(android.transition.Transition)). But animations have limitations compared to Transitions - Animations have to be resx files so can’t be defined declaratively in React - Android’s Material Transforms are built around Transitions - Native shared elements only support Transitions Images disappearing during Transitions is [a known Fresco bug](https://github.com/facebook/fresco/issues/2512). This PR applies [the fix suggested by the Fresco repo](https://github.com/facebook/fresco/issues/1445#issuecomment-315763953). ## Changelog: [ANDROID] [FIXED] - Support Android Transitions during Fragment navigation Pull Request resolved: https://github.com/facebook/react-native/pull/37857 Test Plan: I’ve created a [minimal reproduction that demonstrates the bug](https://github.com/grahammendick/image-disappears-during-transition-bug). The first video below shows the example from that repo. You can see that the image disappears when changing the painting. It should fade out and in like the text does. The second video shows the same example after the fix is applied. You can see that the painting fades out and in just like the text. https://github.com/facebook/react-native/assets/1761227/6739f029-eda0-44d2-b328-a73b075bd82a https://github.com/facebook/react-native/assets/1761227/9c73cdf0-303b-4a82-8df5-5f6a5846a58e Reviewed By: javache Differential Revision: D46769995 Pulled By: dmytrorykun fbshipit-source-id: 0ced8af7b246d8c59cbfb5cabf422114c6154c65 --- .../java/com/facebook/react/views/image/ReactImageView.java | 3 +++ 1 file changed, 3 insertions(+) diff --git a/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/image/ReactImageView.java b/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/image/ReactImageView.java index 30a6ed20bdf..da4fad4b4c7 100644 --- a/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/image/ReactImageView.java +++ b/packages/react-native/ReactAndroid/src/main/java/com/facebook/react/views/image/ReactImageView.java @@ -152,6 +152,9 @@ public class ReactImageView extends GenericDraweeView { mDraweeControllerBuilder = draweeControllerBuilder; mGlobalImageLoadListener = globalImageLoadListener; mCallerContext = callerContext; + // Workaround Android bug where ImageView visibility is not propagated to the Drawable, so you + // have to manually update visibility.
