打开抽屉时，我点击图标反应导航版本5

Question

当我点击标题左侧部分的图标时，我想打开抽屉，我也必须尝试this.props.navigation.dispatch，但is也给出了错误navigation.dispatch给出了错误

下面的代码没有给出错误，但没有打开抽屉

import { DrawerActions } from '@react-navigation/native';
import { NavigationContainer } from '@react-navigation/native';
import { createDrawerNavigator } from '@react-navigation/drawer';
import { createStackNavigator } from '@react-navigation/stack';
const Drawer = createDrawerNavigator();
const Stack = createStackNavigator();
export default class App extends Component {
createHomeStack = () =>
<Stack.Navigator>
<Stack.Screen
initialRouteName="login"
headerMode="screen"
name="main"
children={ this.createBottomTabs}
options={{
title: "Fitbit",
headerLeft: () => (
<Icon
name="menu"
size={25}
color="#D4AF37"
onPress={() => {DrawerActions.openDrawer()  }}
/>
)} } />
</Stack.Navigator>
createDrawer = ({navigation}) =>
<Drawer.Navigator initialRouteName="Main" >
<Drawer.Screen name="Main" component={Main} />
<Drawer.Screen name="Contacts" component={Food} />>
</Drawer.Navigator>
render() {
return ( 
<NavigationContainer>
{this.createHomeStack()}
</NavigationContainer>
);
}
}

为了实现这一点，您需要按照文档所述将堆栈包装到抽屉中。

此处的文档

我可能会使用这样的东西：

编辑：添加完整代码

import React,{Component} from 'react'
import { NavigationContainer } from '@react-navigation/native'
import { createDrawerNavigator } from '@react-navigation/drawer'
import { createStackNavigator } from '@react-navigation/stack'
import { View } from 'react-native'
import Icon from 'react-native-vector-icons/dist/Feather'
const Drawer = createDrawerNavigator()
const Stack = createStackNavigator()
const Main = () => <View></View>
const Food = () => <View></View>
const Home = ({ navigation }) => (
<Stack.Navigator>
<Stack.Screen name="Main" component={Main} options={{
headerLeft: () => <Icon
name="menu"
size={25}
color="#D4AF37"
onPress={() => navigation.openDrawer()}
/>
}} />
</Stack.Navigator>
)

const DrawerNavigator = () => (
<Drawer.Navigator initialRouteName="Home">
<Drawer.Screen name="Home" component={Home} />
<Drawer.Screen name="Contacts" component={Food} />
</Drawer.Navigator>
)
export default props => (
<NavigationContainer>
<DrawerNavigator />
</NavigationContainer>
)

您需要导入DrawerActions

import {DrawerActions } from '@react-navigation/native';

你可以使用打开

navigation.dispatch(DrawerActions.openDrawer());
