【问题描述】：

问题

当react-native-swiper 如下图移动时，下方的蓝色活动按钮不会更新。

对于 swiper，我正在使用 map() 函数创建一个视图。

请注意，将键（索引）传递给子视图组件不会更新蓝色按钮。

如果我在不使用 swiper 中的 map() 函数的情况下对视图进行硬编码，则该按钮将起作用。

有什么问题？

【参考方案1】：

发现 here 的建议解决方法是从您的 Swiper 组件中删除 style 属性。

要获得您想要的边框，您可以将您的 swiper 包裹在父视图中。希望这会有所帮助。

不幸的是，当我从 Swiper 组件中删除样式时，按钮没有更新..
