描述

我正在尝试在可按压的元素获得焦点时添加自定义焦点样式，以使键盘焦点在任何情况下(深色/浅色模式，不同的背景颜色等)都可见。
看起来 TouchableOpacity 和 TouchableHightlight 都从 TouchableWithoutFeedback 转发而来，而 TouchableWithoutFeedback 具有 onFocus 和 onBlur 事件。我曾试图使用这些事件保持焦点状态以动态渲染样式。然而，它们根本不会被触发，即使我使用 TouchableWithoutFeedback,这让我认为这就是问题所在。
可访问性需要可见的焦点状态。是否有其他方法来获取焦点状态？

重现步骤

这是一个小示例：

const [isFocused, setIsFocused] = useState(false);

return (
  // same with `TouchableWithoutFeedback` and `TouchableOpacity`
  <TouchableHighlight
    onFocus={() => setIsFocused(true)}
    onBlur={() => setIsFocused(false)}
    style={{
      backgroundColor: isFocused?"gray":"transparent",
    }}
  >
    ...
  </TouchableHighlight>
);
