若要使SafeAreaView不受React Native Expo应用中键盘的影响，可以使用KeyboardAvoidingView组件。使用KeyboardAvoidingView Package SafeAreaView组件，并将behavior属性设置为padding或height。例如：

import React from 'react';
import { KeyboardAvoidingView, SafeAreaView, Text } from 'react-native';

const App = () => {
  return (
    <KeyboardAvoidingView
      style={{ flex: 1 }}
      behavior={Platform.OS === 'ios' ? 'padding' : 'height'}
      keyboardVerticalOffset={100}
    >
      <SafeAreaView style={{ flex: 1, backgroundColor: 'white' }}>
        <Text>My App Content</Text>
      </SafeAreaView>
    </KeyboardAvoidingView>
  );
};

export default App;

此代码将通过添加填充或调整键盘高度来使SafeAreaView组件不受键盘影响。keyboardVerticalOffset属性可用于在键盘和SafeAreaView之间添加或减去额外的空间。
