描述
Description
On Android with TalkBack on, TouchableOpacity/Pressable components do not trigger PanResponder callbacks when pressed if the TouchableOpacity/Pressable has on onPress prop and its focusable prop is not false.
Steps to reproduce
- Create a PanResponder and apply its panHandlers to a View.
- Add a Pressable inside the View and give it an onPress prop.
- View the app in Android with TalkBack on.
- Double-tap to activate, observe the pan responder callbacks DO NOT fire.
Furthermore, double-tapping a non-TouchableOpacity/Pressable element such as a Text component will trigger PanResponder callbacks.
In the example repo I provided it should print "PanResponder Callback Triggered' but its only printing "ON PRESS TRIGGERED"

调研方向
从链接的 reproducer 开始,在启用 TalkBack 的 Android 上,使用所述的 PanResponder、Pressable 和 TouchableOpacity 场景重现该问题。跟踪从 TalkBack 激活开始,经由 Pressable 或 TouchableOpacity,到 PanResponder 回调的交互过程。当 PanResponder 回调在报告的场景中触发,同时 onPress 回调继续正常工作时,即表示完成。
