This is a simple 3-page application that demonstrates the basic usage of React Navigation as a navigation tool. It is extremely easy to understand. This step-by-step tutorial will take you through the basic concepts. We are using NativeBase as the UI library to design our pages.



Aim

We are creating a 3-page application with buttons on each page that takes us to the other page onPress.

Installation

  1. Create React Native App: Use CRNA tool to create an App like this

    stiletto toe black women shoes sale heel Hot pointed $ npm install -g create-react-native-app
    $ create-react-native-app my-app
    $ cd my-app/
    $ npm start
  2. Installing Libraries
    women heel black stiletto sale shoes toe Hot pointed
    With a React Native project SetUp, We can now install all required Libraries as follows.
    a. React Navigation

    npm install --save react-navigation
    b. NativeBase
    npm install native-base --save
    c. Configure dependencies
    react-native link
    By the end of Installation, your package.json file should look something like this.


Lets Play

With our basic project setup we can now start building our App.
stiletto toe heel pointed shoes women sale black Hot
Make a folder at the project root by the name of src.
Inside this folder we make 3 folders:

  • ChatScreen
  • toe stiletto heel women shoes black Hot sale pointed HomeScreen
  • ProfileScreen

HomeScreen

This is going to be the first landing screen of out App. We are going to implement the navigation logic here.
For our purpose here, we have used DrawerNavigator for navigation through the entire app.
Further screens will have nested navigators in them.
Go ahead and add the following file in your project.

Code HomeScreen/HomeScreen.js

import React from "react";
import { StatusBar } from "react-native";
import { Container, Header, Title, Left, Icon, Right, Button, Body, Content,Text, Card, CardItem } from "native-base";
export default class HomeScreen extends React.Component {
  render() {
    return (
      
        
HomeScreen
Chat App to talk some awesome people!
); } }

Explained

Code HomeScreen/index.js

toe Hot pointed black heel shoes stiletto sale women import React, { Component } from "react";
import HomeScreen from "./HomeScreen.js";
import MainScreenNavigator from "../ChatScreen/index.js";
import Profile from "../ProfileScreen/index.js";
import SideBar from "../SideBar/SideBar.js"Sport Kind Football Sportive Shoe Man dSRBU;
import { DrawerNavigator } from "react-navigation";
const HomeScreenRouter = DrawerNavigator(
  {
    Home: { screen: HomeScreen },
    Chat: { screen: MainScreenNavigator },
    Profile: { screen: Profile }
  },
  {
    contentComponent: props => <SideBar {...props} /> } ); export default HomeScreenRouter;

Explained

  • Here we have simply imported all the screens we will be needing. We will be building these screens in the comming sections. These screens in fact are router components which themselves have multiple screens.
  • We pass the screens to the DrawerNavigator as shown above.
  • Note how we have used a custom NativeBase components using customComponent prop and we pass our custom drawer component.

This is going to be our custom drawer component where we put buttons to navigate to different screens available.
Navigation object is available as this.props.navigation since we passed the props in the HomeScreen component.

Code SideBar/SideBar.js

import React from "react";
import { AppRegistry, Image, StatusBar } from "react-native";
import { Container, Content, Text, List, ListItem } from "native-base";
const routes = ["Home", "Chat", "Profile"];
export default class SideBar extends Reactmatching wholesale shoe woman bag and italian fq5prq8.Component {
  render() {
    return (
      
        
          
            
          
           {
              return (
                 this.props.navigation.navigate(data)}>
                  {data}
                
              );
            }}
          />
        
      
    );
  }
}

ChatScreen

This screen comprises of TabNavigator component. We are going to have three screens here to chat to three different people.
We will also create our own custom component for Tabs. Its done as follows.

Code ChatScreen/index.js

import React, { Component } from heel stiletto women sale shoes Hot pointed toe black "react";
import LucyChat from "./LucyChat.js";
import JadeChat from "./JadeChat.js";
import NineChat from "./NineChat.js";
import { TabNavigator } from "react-navigation";
import { Button, Text, Icon, Footer, FooterTab } from "native-base"8 shoe with different led Man light changable PnptZ;
export default (MainScreenNavigator = TabNavigator(
  {
    LucyChat: { screen: LucyChat },
    JadeChat: { screen: JadeChat },
    NineChat: { screen: NineChat }
  },
  {
    tabBarPosition: "bottom",
    tabBarComponent: props => {
      return (
        
); } } ));

Explained

  • We have simply imported three screens to work as Tabs as shown above.
  • We pass these screens to TabNavigator component.
  • Notice how we pass our Tab component through tabBarComponent prop.
  • Navigation is available as props.

Sample screen

Code ChatScreen/LucyChat.js

import React from "react";
import { AppRegistry, View, StatusBar } from "react-native";
import { Container, Body, Content, Header, Left, Right, Icon, Title, Input, Item, Label, Button, Text } from "native-base";
toe stiletto heel shoes pointed black women Hot sale import HomeScreen from "../HomeScreen";
export default class sale stiletto Hot toe women shoes heel pointed black LucyChat extends React.Component {
  render() {
    const { navigate } = this.props.navigation;
    return (
      
        
Lucy Chat
); } }

Profile

This screen includes example for StackNavigation.
Code ProfileScreen/index.js

import React, { Component } from "react";
import Profile from "./Profile.js";
import EditScreenOne from "./EditScreenOne.js";
import EditScreenTwo from "./EditScreenTwo.js";
import { StackNavigator } from "react-navigation";
export default (DrawNav = StackNavigator({
  Profile: { screen: Profile },
  EditScreenOne: { screen: EditScreenOne },
  EditScreenTwo: { screen: EditScreenTwo }
}));

Code ProfileScreen/Profile.js

import React from "react";
import { AppRegistry, Alert } from "react-native";
import { Container, Header, Left, Body, Title, Card, CardItem, Content, Right, Icon, Button, Text } from "native-base";
import { StackNavigator } from "react-navigation";
import EditScreenOne from "./EditScreenOne.js";
import EditScreenTwo from "./EditScreenTwo.js";
pointed shoes sale Hot toe heel women black stiletto export default shoes toe black sale stiletto pointed Hot heel women class Profile extends React.Component {
  componentDidMount() {
    Alert.alert("No Users Found", "Oops, Looks like you are not signed in");
  }
  render() {
    return (
      
        
          
            
              
              Show User profiles here
              
                
              
            
          
          
        
      
    );
  }
}
Profile.navigationOptions = ({ navigation }) => ({
  header: (
    
Profile
) });

Explained

  • We have Navigation as a StackNavigation prop here. In the UI, we have different buttons to navigate to screens on stack. Notice how we imported screens above.
  • Notice how we passed the DrawerNavigator prop inside our Profile screen header above.

Code ProfileScreen/EditScreenOne.js
This screen is a simple part of StackNavigation, we have a header with a back button as shown below.

import React from "react";
import { AppRegistry, Alert } from "react-native";
import { Container, Card, CardItem, Body, Content, Header, Left, Right, Icon, Title, Button, Text } from "native-base";
export default class EditScreenOne extends React.Component {
  static navigationOptions = ({ navigation }) => ({
    header: (
      
EditScreenOne
) }); render() { return ( Edit Screen 1 ); } }

Finishing up

Lastly we import our routes component from HomeScreen to our App.js file as shown.
Note how we have loaded fonts for NativeBase since we have used expo here.

Code App.js

importBreathable Velvet with Holes Plain Shoes Mens ZPvW8qRrwZ React, { Component } from "react";
shoes sale pointed women toe Hot heel stiletto black import Expo from "expo";
import HomeScreen from "./src/HomeScreen/index.js";
export default class AwesomeApp extends heel stiletto Hot toe black women pointed shoes sale Component {
  constructor() {
    super();
    this.state = {
      isReady: false
    };
  }
  asyncStyle Shoes Diy Best Casual Leather New China Bqrqx5YXw componentWillMount() {
    await Expo.Font.loadAsync({
      Roboto: require("native-base/Fonts/Roboto.ttf"),
      Roboto_medium: require("native-base/Fonts/Roboto_medium.ttf"),
      Ionicons: require("native-base/Fonts/Ionicons.ttf")
    });
    this.setState({ isReady: true });
  }
  render() {
    if (!this.state.isReady) {
      return ;
    }
    return ;
  }
}

All has been taken care of now. Build and run.
