如何在抽屉上显示react redux的提取.屏幕标题

Question

我想在抽屉屏幕的状态标题栏上显示数据。

我的代码：

import React, {useEffect, useRef, useState} from 'react';
import {Dimensions, FlatList, Text} from 'react-native';
import {useDispatch, useSelector} from 'react-redux';
import AsyncStorage from '@react-native-async-storage/async-storage';
import {get_agency_direction} from '../store/Log/Dir/DirActions';
import Direction from '../screens/Direction/Direction';
import {createDrawerNavigator} from '@react-navigation/drawer';
const Drawer = createDrawerNavigator();
const RDirection = () => {`enter code here`
const info_agency = useSelector(state => state.DirReducers.info_agency);
const dispatch = useDispatch();
useEffect(() => {
try {
AsyncStorage.getItem('token').then(async value => {
dispatch(get_agency_direction(value));
});
} catch (e) {
console.log(e);
}
});
console.log(info_agency);
return (
<Drawer.Navigator
initialRouteName="Direction"
screenOptions={{
drawerStyle: {
width: Dimensions.get('window').width - 40,
},
}}
drawerType="permanent"
drawerContent={props => <DrawerDirection {...props} />}
backBehavior="history">
<Drawer.Screen
name="Direction"
component={Direction}
options={({navigation}) => ({
header: () => (
<HeaderUser
Gtitle='Noblesse voyages'
Depart="Douala"
Arrive="Yaoundé"
onPress={() => {
navigation.toggleDrawer();
}}
/>
),
headerStyle: {
height: 70,
},
})}
/>
</Drawer.Navigator>
);
};
export default RDirection;

console.log(info_agency(的返回代码：

[{
"id":46,
"NomCh":"Bricks",
"PrenomCh":"Wandem foué",
"MotdepasseCh":"$2b$10$/4ugSQMptSp6VqScLcHl4.V9oyrgnAk7NNmtZIeRZ7usT1hcMsbB2",
"NumeroCh":673845359,
"NomAgence":"Talla voyages",
"NomOrganisation":"Talla",
"idch":49,
"CodesecureAgence":"$2b$10$lJ0oBoWr7vnI0Ix.YpWDo.tsiYJ8bSm/yLhVSDf8kgT4CfYFZm7Bm",
"NumeroSerieAg":"",
}]

我会有一辆像那样的卡车

header: () => (
<HeaderUser
Gtitle={info_agency.NomAgence}
Depart={/* Not important*/}
Arrive={/* Not important*/}
onPress={() => {
navigation.toggleDrawer();
}}
/>

我尝试了使用Flatlist，但没有成功。

您的console.log显示您的响应返回一个数组。你正试图打电话给信息机构。NomAgence不会工作，因为它不是一个对象。

如果你想把标题传给Gtitle，你需要从数组中获得对象：

info_agency[0].NomAgence
