调研方向
首先在 Android 上运行链接的 Snack reproducer,并将其触摸行为与 iOS 进行比较,以包含 Switch 或 WebView 的绝对定位子元素作为切入点。跟踪 Android 对超出父元素边界的子元素的触摸处理。完成的标准是父元素外部的部分也能接收交互,同时不改变父元素内部的行为。

描述
Description
<GestureHandlerRootView style={styles.root}>
<GestureDetector gesture={composedGesture}>
<Animated.View style={styles.canvasWrapper}>
// the red box
<Animated.View style={[styles.canvasTransform, canvasAnimatedStyle]}>
<Animated.View
style={{
position: 'absolute',
left: 300,
top: 0,
}}
collapsable={false}>
<YoutubePlayer height={300} width={400} videoId={'HzL65tTeANs'} play={true} />
</Animated.View>
</Animated.View>
<Animated.View style={focalPointStyle} pointerEvents="none" />
</Animated.View>
</GestureDetector>
</GestureHandlerRootView>
I have a parent <Animated.View> (the red box in my demo). Inside it, I have another <Animated.View> that’s absolutely positioned and contains a react-native-youtube-iframe player
When the absolutely positioned animated.view is inside the red box(the parent), everything works fine. I can play pause and interact with the video
But once it goes outside the parent bounds, the video stops receiving touches.
as you can see from my demo video that only the part of the video inside the red box receives touch events
Note: the problem is not related to react-native-youtube-iframe i tested it with a regular React Native component like <Switch /> and the same behavior occurs with only android
Steps to reproduce
1- Create a parent <Animated.View> that acts as a container
2- Inside it, create another <Animated.View> with position: 'absolute' and place it so that part of it goes outside the parent’s bounds.
3- Inside the absolutely positioned animated.view, render for example <Switch /> or even a WebView.
4- Run the app on Android.
5- Try interacting with the <Switch />:
When the absolutely positioned animated.view and the switch are inside the parent's layout, the switch works fine.
When you move the absolutely positioned animated.view and the switch are outside the parent’s layout. the switch doesn't work
6- Run the same code on iOS. everything works fine
