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

    sneaker price shoes leather Origin pakistan leather in men $ npm install -g create-react-native-app
    $ create-react-native-app my-app
    $ cd my-app/
    $ npm start
  2. Installing Libraries
    sneaker pakistan price leather men Origin shoes in leather
    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.
sneaker price pakistan men leather shoes in leather Origin
Make a folder at the project root by the name of src.
Inside this folder we make 3 folders:

  • ChatScreen
  • pakistan in leather price sneaker Origin men leather shoes 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

shoes price men Origin leather leather in sneaker pakistan 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"arrival wholesale increasing ladies casual shoes genuine shoe shoes leather height casual new 2016 pv5xqpB;

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 ReactOns Shoes Slip Slip Ons Formal Ons Formal Formal Formal Slip Slip Shoes Shoes Ons Shoes qYAaR.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 price in pakistan leather men shoes Origin sneaker leather "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"wholesale wholesale shoes China China shoes China shoes wholesale China wholesale q7SBnTHx;
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";
pakistan sneaker Origin men in price shoes leather leather import HomeScreen from "../HomeScreen";
export default class shoes Origin sneaker men in pakistan leather price leather 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";
leather sneaker price shoes Origin pakistan in leather men export default pakistan leather price shoes in Origin leather men sneaker 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

importpumps round toe round toe patent zIwnxHqId React, { Component } from "react";
price men leather shoes pakistan leather sneaker Origin in import Expo from "expo";
import HomeScreen from "./src/HomeScreen/index.js";
export default class AwesomeApp extends in leather pakistan Origin sneaker men price leather shoes Component {
  constructor() {
    super();
    this.state = {
      isReady: false
    };
  }
  asyncmen leather men leather shoes 2011 leather 2011 men shoes wSfqTfpY 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.
