Question

我正在尝试创建一个带有带有四个屏幕选项卡菜单的底部导航选项卡的应用程序。我想为“管理员”创建另一个页面，但菜单选项不应出现在底部选项卡上。（我必须转到该页面）我正在使用react-navigation-material-bottom-tabs创建底部的标签栏。

我需要一种前往该页面的方法。

export default createMaterialBottomTabNavigator(

  {
    Home: {
      screen: HomeScreen,
      navigationOptions: {
        title: "Home",
        tabBarLabel: <Text style={{ color: "white" }}>Home</Text>,
        barStyle: { backgroundColor: "#281b39" },
        tabBarIcon: <Icon size={24} name="home" style={{ color: "white" }} />
      }
    },
    Announcement: {
      screen: AnnouncementScreen,
      navigationOptions: {
        title: "Announcement",
        tabBarLabel: <Text style={{ color: "white" }}>Announcements</Text>,
        barStyle: { backgroundColor: "#0e141d" },
        tabBarIcon: (
          <Icon size={24} name="bullhorn" style={{ color: "white" }} />
        )
      }
    },
    Material: {
      screen: MaterialScreen,
      navigationOptions: {
        title: "Materials",
        tabBarLabel: <Text style={{ color: "white" }}>Materials</Text>,
        barStyle: { backgroundColor: "#E64A19" },
        tabBarIcon: (
          <Icon size={24} name="calendar" style={{ color: "white" }} />
        )
      }
    },
    Contact: {
      screen: ContactScreen,
      navigationOptions: {
        title: "Contact",
        tabBarLabel: <Text style={{ color: "white" }}>Contact</Text>,
        barStyle: { backgroundColor: "#524365" },
        tabBarIcon: (
          <Icon size={24} name="comments" style={{ color: "white" }} />
        )
      }
    },   },

  {
    shifting: true,
    labeled: true   } );

这是更新版本

const App = createAppContainer(AppNavigator);

export default App;

您可以使用StackNavigator转到新屏幕。

import React from "react";
import { StyleSheet, Text, View } from "react-native";
import { createStackNavigator, createAppContainer } from "react-navigation";
import { createMaterialBottomTabNavigator } from "react-navigation-material-bottom-tabs";

class Home extends React.Component {
  render() {
    const { navigation } = this.props;

    return (
      <View style={styles.container}>
        <Text onPress={() => navigation.navigate("Admin")}>Home</Text>
      </View>
    );
  }
}

class Announcement extends React.Component {
  render() {
    const { navigation } = this.props;

    return (
      <View style={styles.container}>
        <Text onPress={() => navigation.navigate("Admin")}>Announcement</Text>
      </View>
    );
  }
}

class Material extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text>Material</Text>
      </View>
    );
  }
}

class Contact extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text>Contact</Text>
      </View>
    );
  }
}

class Admin extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text>Admin</Text>
      </View>
    );
  }
}

const commonScreens = {
  Admin: {
    screen: Admin
  }
};

const HomeStack = createStackNavigator({
  Home: {
    screen: Home
  },
  ...commonScreens
});

const AnnouncementStack = createStackNavigator({
  Announcement: {
    screen: Announcement
  },
  ...commonScreens
});

const AppNavigator = createMaterialBottomTabNavigator(
  {
    Home: { screen: HomeStack },
    Announcement: { screen: AnnouncementStack },
    Material: { screen: Material },
    Contact: { screen: Contact }
  },
  {
    initialRouteName: "Home",
    activeColor: "#f0edf6",
    barStyle: { backgroundColor: "#694fad" },
    labeled: true
  }
);

export default createAppContainer(AppNavigator);

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#fff",
    alignItems: "center",
    justifyContent: "center"
  }
});

还有一些用于删除标题的选项。有关更多信息，请查看文档https://reactnavigation.org/docs/en/stack-navigator.html#stacknavigatorconfig
