useEffect不会在第二次渲染时或在我第二次进入屏幕时被调用

Question

我的useEffect仅是第一次被调用，后来却没有被调用

import React, { useEffect, useState } from 'react';
import { View, Text, ScrollView } from 'react-native';
import HeaderNavigationBar from '../components/HeaderNavigationBar';
import CustomCard from '../components/CustomCard';
import { useSelector, useDispatch } from 'react-redux'
import * as OrderActions from '../store/actions/order';

export const AccountHistoryScreen = props => {
    const orders = useSelector(state => state.orders)
    const auth = useSelector(state => state.auth);
    const dispatch = useDispatch()
    useEffect(()=> {
        dispatch(OrderActions.getOrders())
    },[dispatch])
        return (<View style={{
            flex: 1,
            flexDirection: 'column',
        }}> 
        <HeaderNavigationBar {...props} />
            <View style={{
                flex: 1
            }}>
          <ScrollView>
           {orders.result && orders.result.length > 0 && orders.result.map((order, index) => 
           <CustomCard key={index} order={order}/>)} 
           </ScrollView>
           {orders.result && orders.result.length === 0 && <View style={{
               justifyContent: 'center',
               alignItems: 'center',
               height: '100%',
           }}><Text style={{fontSize: 20}}>No orders Placed Yet</Text></View>}
            </View>
        </View>);
}

export default AccountHistoryScreen;

这是我的组件，每当我从抽屉式导航器进入此“帐户历史记录”屏幕时，我都想获取订单
