我们尝试通过添加以下代码对其进行修复

import { Platform,TextInput } from 'react-native';

const {版本} =平台；

const brandNeedingWorkaround = ['redmi'，'xiaomi'，'poco'，'pocophone']； const needsXiaomiWorkaround = brandNeedingWorkaround.includes（RNInfo.getBrand（）。toLowerCase（）） &&版本> 28;

const Inputtextwrapper = forwardRef（（{{onFocus，caretHidden，... others}，ref）=> { const [hackCaretHidden，setHackCaretHidden] = useState（needsXiaomiWorkaround？true：caretHidden）; 

const handleFocus = useCallback(() => {
    if (needsXiaomiWorkaround) {
        setHackCaretHidden(caretHidden);
    }
    if (onFocus) onFocus();
},[onFocus,caretHidden]);

return (
    <TextInput
        ref={ref}
        {...others}
        onFocus={handleFocus}
        caretHidden={hackCaretHidden}
    />
);

}）;

但是仍然无法正常工作。请为我们提供解决此问题的解决方案。

解决方法

我希望这可以为您提供帮助

一些开发人员可以在TextInput中使用“可编辑”道具来工作

const [editable,setEditable] = React.useState(false)

React.useEffect(() => {
  React.useEffect(() => {
  setTimeout(() => {
    setEditable(true)
  },100)
},[])

return (
  <TextInput
    editable={editable}
    ...
  />
)
,

或者干脆

const [editable,setEditable] = useState(false);

useEffect(() => {
    setEditable(true);
  },[]);

<TextInput
editable={editable}
/>

也帮我解决了
