如何在 React Navigation 中的 Stack Navigation 中添加抽屉

Question

我正在做一个像登录/注册应用程序这样的实践项目，我正在使用 react-navigations 中的堆栈导航，它运行良好，

现在，当用户登录时，他应该被重定向到仪表板屏幕，我希望在标题右侧有一个抽屉“我还添加了一个屏幕截图”，并且我也在 Stack 中创建了仪表板屏幕导航我不知道如何在堆栈导航中添加抽屉 我只想在仪表板屏幕上添加抽屉以便任何人都可以提供帮助？谢谢

App.js（我在其中添加了所有堆栈屏幕）

    import React from 'react';

    import { createStackNavigator, createDrawerNavigator } from 'react-navigation';

    import HomeScreen from './screens/HomeScreen';
    import LoginScreen from './screens/LoginScreen';
    import RegisterScreen from './screens/RegisterScreen';
    import Dashboard from './screens/Dashboard';

    const StackNavigation = createStackNavigator({
      HomeStack: HomeScreen,
      LoginStack: LoginScreen,
      RegisterStack: RegisterScreen,
      DashboardStack: Dashboard,

    }, {
        initialRouteName: 'HomeStack',
      });

      const DrawerNav = createDrawerNavigator({
        DashboardStack: Dashboard,
      })


    export default class App extends React.Component {
      render() {
        return (
          <StackNavigation />
        );
      }
    }

仪表板.js

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

    import Icon from 'react-native-vector-icons/FontAwesome';

    export default class Dashboard extends React.Component {

        static navigationOptions = {

            headerTitle: 'Dashboard',
            headerLeft: null,

            headerTitleStyle: {
                flex: 1,
                color: '#fff',
                textAlign: 'center',
                alignSelf: 'center',
                fontWeight: 'normal',
            },

            headerStyle: {
                backgroundColor: '#b5259e',
            },
        }

从右侧显示抽屉。

在创建抽屉导航器时添加drawer Position参数。

const DrawerNav = createDrawerNavigator({
  DashboardStack: Dashboard, 
},
{
  drawerPosition: 'right'
});

从标题按钮调用 DrawerNavigation。

在Dashboard.js 中为toggleDrawer 的标题添加一个按钮。您可以在navigationOptions中获取如下导航实例；

class Dashboard extends React.Component {
  static navigationOptions = ({navigation, navigationOptions}) => {
    return {
      headerTitle: 'Dashboard@@',
      headerLeft: <Text>Left</Text>,
      headerRight: (
        <Button onPress = {navigation.toggleDrawer}
        title="Menu"
        color="#fff">
          <Text>Menu</Text>
        </Button>
      ),
      headerTitleStyle: {
        flex: 1,
        color: '#fff',
        textAlign: 'center',
        alignSelf: 'center',
        fontWeight: 'normal',
      },

      headerStyle: {
        backgroundColor: '#b5259e',
      },
    }
  }

您可以将按钮更改为 Touchable Opacity 或其他按钮。

使用另一个导航器包装 AuthStackNavigation 和 DrawerNavigation。

使用createSwitchNavigation 或其他方法包装您的导航并导出。

// App.js

import React from 'react';

import {
  createStackNavigator,
  createDrawerNavigator,
  createSwitchNavigator,
} from 'react-navigation';

import HomeScreen from './srcs/screens/Home';
import Dashboard from './srcs/screens/Dashboard';

const AuthStackNavigation = createStackNavigator({
  HomeStack: HomeScreen,
  LoginStack: HomeScreen,
  RegisterStack: HomeScreen,
}, {
  initialRouteName: 'HomeStack',
})

const DashboardStack = createStackNavigator({ // For header options
  Dashboard: Dashboard
})

const DrawerNav = createDrawerNavigator({
  DashboardStack: DashboardStack,
  SecondScreen: Dashboard, // You should use another screen.
  ThirdScreen: Dashboard,
})

const MainNavigation = createSwitchNavigator({
  HomeDrawer: DrawerNav,
  AuthStack: AuthStackNavigation, // You will use this.props.navigation.replace('HomeDrawer') after login process.
})

export default MainNavigation // Stack, Drawer, Switch naviagtions return react component.

我刚刚创建了一个您可能需要的示例。

import React, {Component} from 'react';
import {
  StyleSheet,
  Button,
  Image,
  TouchableWithoutFeedback,
  View,
} from 'react-native';
import {
  createDrawerNavigator,
  createStackNavigator,
  StackActions,
  NavigationActions,
} from 'react-navigation';


class HomeScreen extends React.Component {
  render() {
    return (
        <View style={styles.container}>
          <Button
              onPress={() => this.props.navigation.navigate('Notifications')}
              title="Go to notifications"
          />
        </View>
    );
  }
}

class NotificationsScreen extends React.Component {
  render() {
    return (
        <View style={styles.container}>
          <Button
              onPress={() => this.props.navigation.navigate('Home')}
              title="Go back home"
          />
        </View>
    );
  }
}

class LoginScreen extends Component {
  openDashboard = () => {
    const resetAction = StackActions.reset({
      index: 0,
      actions: [NavigationActions.navigate({routeName: 'Dashboard'})],
    });
    this.props.navigation.dispatch(resetAction);
  }

  render() {
    return (
        <View style={styles.container}>
          <Button
              onPress={this.openDashboard}
              title={'Login'}
          />
        </View>
    )
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    paddingHorizontal: 20,
  },
  icon: {
    width: 24,
    height: 24,
  },
  menu: {
    marginRight: 8,
  }
});

const renderMenu = (navigation) => (
    <TouchableWithoutFeedback onPress={() => navigation.openDrawer()}>
      <Image
          source={require('./menu.png')}
          style={[styles.icon, styles.menu]}
      />
    </TouchableWithoutFeedback>
)

const Home = createStackNavigator({
  Home: {
    screen: HomeScreen,
    navigationOptions: ({navigation}) => ({
      title: 'Home',
      headerRight: renderMenu(navigation)
    }),
  }
})

const Notifications = createStackNavigator({
  Notifications: {
    screen: NotificationsScreen,
    navigationOptions: ({navigation}) => ({
      title: 'Notifications',
      headerRight: renderMenu(navigation)
    })
  }
})

const Dashboard = createDrawerNavigator(
    {
      Home: {
        screen: Home,
        navigationOptions: {
          drawerLabel: 'Home',
          drawerIcon: (
              <Image
                  source={require('./chats-icon.png')}
                  style={styles.icon}
              />
          ),
        }
      },
      Notifications: {
        screen: Notifications,
        navigationOptions: {
          drawerLabel: 'Notifications',
          drawerIcon: (
              <Image
                  source={require('./notif-icon.png')}
                  style={styles.icon}
              />
          ),
        }
      },
    },
    {
      drawerPosition: 'right'
    }
);

const App = createStackNavigator(
    {
      Login: LoginScreen,
      Dashboard: Dashboard
    },
    {
      initialRouteName: 'Login',
      headerMode: 'none'
    }
)

export default App;

• 当用户按下 LoginScreen 上的登录按钮时，导航将被重置（这样用户就无法通过返回箭头或 android 上的物理返回按钮返回登录屏幕）。
• 然后我们在右侧创建一个带有两个屏幕和一个汉堡图标的抽屉。
• Home 的子屏幕应位于 Home 堆栈中，通知也应如此。

您只需要添加缺少的图标。

Answer 3

对于那些在react-navigation5.X中寻找解决方案的人，你可以这样做：

抽屉导航器

const ProductListWithDrawer = () => {
 return (
  <Drawer.Navigator initialRouteName="ProductList">
   <Drawer.Screen name="ProductList" component={screens.ProductList} />
   <Drawer.Screen name="ProductDetail" component={screens.ProductDetailScreen} />
  </Drawer.Navigator>
  );
 };

Stack Navigator（应该包裹在Navigation Container中）

<Stack.Navigator initialRouteName="Dashboard" screenOptions={{ headerShown: false }}>
  <Stack.Screen name="Dashboard" component={screens.Dashboard} />
  <Stack.Screen name="Loading" component={screens.Loading} />
  <Stack.Screen name="Chat" component={screens.Chat} />
  <Stack.Screen name="ProductListWithDrawer" component={ProductListWithDrawer} /> //our drawer
</Stack.Navigator>

基本上，这应该可以完成工作。这里可能存在的另一件事是在使用参数导航到抽屉导航器内的那些屏幕时。在这种情况下，可以这样做：

navigation.navigate("ProductListWithDrawer", {
              screen: "ProductList",
              params: { user: "Alex"},
            });

这在Nesting navigators中也有解释。
