使用钩子使用React Native执行goBack时刷新屏幕A

import React, { useState } from 'react';
import { View, Text, Button } from 'react-native';

const ScreenA = ({ navigation }) => {
  const [refresh, setRefresh] = useState(false);

  const handleGoBack = () => {
    setRefresh(true);
    navigation.goBack();
  };

  return (
    <View>
      <Text>Screen A</Text>
      <Button title="Go Back" onPress={handleGoBack} />
    </View>
  );
};

export default ScreenA;

import React, { useFocusEffect } from 'react';
import { View, Text } from 'react-native';

const ScreenB = ({ navigation }) => {
  useFocusEffect(
    React.useCallback(() => {
      navigation.navigate('ScreenA');
    }, [])
  );

  return (
    <View>
      <Text>Screen B</Text>
    </View>
  );
};

export default ScreenB;
