[ 卡卡 DAY 26 ] - React Native 手机装置 keyboard 之乱之键盘挡住元件与键盘点萤幕收起来

手机装置切完版後才会发现
啊～～～还没完成
今天我们来针对键盘挡住元件做个处理吧！！
来介绍个插件 react-native-keyboard-aware-scrollview
这个套件可以在键盘跑出来的时候有 scroll 的功能防止元件被挡住

安装

npm i react-native-keyboard-aware-scroll-view --save
或着
yarn add react-native-keyboard-aware-scroll-view

引入

import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'

放入 KeyboardAwareScrollView

  const Schema = yupObject().shape({
    name: yupString().required('Required'),
    email: yupString().email('Invalid email').required('Required'),
    phone: yupString()
      .matches(phoneRegExp, 'Phone number is not valid')
      .required('Required'),
  });
  const {handleChange, handleSubmit, handleBlur, values, errors, touched} =
    useFormik({
