描述
Description
I am trying to add custom focus styles if a pressable is focused to make the keyboard focus visible in any case (dark/light mode, different background colors etc).
It seems like TouchableOpacity and TouchableHightlight both get forwarded from TouchableWithoutFeedback, which has the onFocus and onBlur events. I was trying to hold a focus state with these events to render styles dynamically. However, they do not get triggered at all, even if I use TouchableWithoutFeedback, which leads me to think that's the culprit.
Accessibility requires visibility of focus states. Is there another way to retrieve focus states?
Steps to reproduce
Here's a little example:
const [isFocused, setIsFocused] = useState(false);
return (
// same with `TouchableWithoutFeedback` and `TouchableOpacity`
<TouchableHighlight
onFocus={() => setIsFocused(true)}
onBlur={() => setIsFocused(false)}
style={{
backgroundColor: isFocused?"gray":"transparent",
}}
>
...
</TouchableHighlight>
);

调研方向
从链接的 focus-example reproducer 开始,跟踪 TouchableHighlight、TouchableOpacity 和 TouchableWithoutFeedback 在 Android 上如何处理 onFocus 和 onBlur。确认键盘焦点行为,并将完成标准定义为焦点事件能够可靠触发,从而可以渲染自定义的可见焦点样式。
