我正在做一个像登录/注册应用程序这样的练习项目，我正在使用 react-navigations 中的 Stack Navigation，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”，并且我也在堆栈导航中创建了仪表板屏幕我不知道如何添加堆栈导航中的那个抽屉我只想在我的仪表板屏幕上使用抽屉，所以任何人都可以提供帮助 谢谢

这就是我想在仪表板屏幕上看到的内容

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。

drawer Position在创建 Drawer Navigator 时添加一个参数。

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

从标题的按钮调用 DrawerNavigation。

toggleDrawer在 in的标题中添加一个按钮Dashboard.js。您可以在以下位置获取导航实例navigationOptions；

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。

包装AuthStackNavigation并DrawerNavigation使用另一个导航器。

使用或其他包装您的导航createSwitchNavigation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后退箭头或 android 上的物理后退按钮返回登录屏幕）。
  • 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 的子屏幕应该在 Home 堆栈内，通知也应如此。

您只需要添加缺少的图标。

react-navigation 对于那些在5.X中寻找解决方案的人，您可以这样做：

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"},
            });

嵌套导航器中也对此进行了解释。
