设备：红米K20 Pro

安卓版本：10

我在android源代码中找不到这部分代码（嗯，似乎是小米修改）

我在 React-Native 社区发现了同样的问题。

关于如何解决它的任何想法？

UPD：我在完全原生的应用程序上遇到了这个崩溃，没有任何跨平台框架。

标签： androidandroid-edittextandroid-10.0xiaomi

解决方案

这次崩溃是操作系统造成的，实际上是小米定制了安卓，10版本的修改导致了这次崩溃。有一个解决方案，caretHidden按值传递标志true，这个问题就会消失：

<TextInput
  caretHidden={true}
  ...

我们可以写得好一点：

<TextInput
  caretHidden
  ...
