Реактивная навигация + реакция-навигация-материалы-вкладки

Question

Я пытаюсь создать приложение с нижней вкладкой навигации с четырьмя меню вкладок.Я хочу иметь другую страницу для администратора, но пункт меню не должен отображаться на нижней вкладке.(Мне нужно перейти на эту страницу) Я использую response-navigation-material-bottom-tabs для создания нижней панели вкладок.

Мне нужен способ перейти на эту страницу.

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   } );

Вы можете использовать StackNavigator для перехода на новый экран.

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"
  }
});

Существуют варианты удаления заголовкатакже.Для получения дополнительной информации, пожалуйста, взгляните на документы https://reactnavigation.org/docs/en/stack-navigator.html#stacknavigatorconfig
