Here is an Example of React Native Tab for Android and IOS. Tabs are the most common style of navigation in mobile apps. Tabs can be on the bottom of the screen or on the top (below the header or even instead of a header). We all have seen WhatsApp and it can’t be so easy without Tab. So let’s get started.
This example will work for the React Navigation Version 3+. If you are using Version 2+ then please find the comments in the code for the suitable changes or can see our old post React Native Navigation Version 2+ for the help.
To Make a React Native App
Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install thereact-native-cli command line utility. Open the terminal and go to the workspace and runInstallation of Dependency
To use TabNavigator you need to install react-navigation package. To install this
Open the terminal and jump into your project
1 | cd ProjectName |
Run the following command.
1 | npm install react-navigation --save |
This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-navigation.
–save is optional, it is just to update the react-navigation dependancy in your package.json file.
Dependency Version for this Example used is
1 | "react-navigation": "3.0.9" |
Project File Structure
To start with this Example you need to create a directory named pages in your project and create two files FirstPge.js and SecondPage.js in it.
Now Open App.js in any code editor and replace the code with the following code.
App.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 | //This is an example of React Native Tab import React from 'react'; //import react in our code. //In Version 2+ //import {createStackNavigator,createMaterialTopTabNavigator} from 'react-navigation'; //In Version 3+ import { createStackNavigator, createMaterialTopTabNavigator, createAppContainer, } from 'react-navigation'; //import Navigator in our project import FirstPage from './pages/FirstPage'; import SecondPage from './pages/SecondPage'; //import TabScreen from './pages/TabScreen'; //Making TabNavigator which will bw called in App StackNavigator //we can directly export the TabNavigator also but header will not be visible //as header comes only when we put anything into StackNavigator and then export const TabScreen = createMaterialTopTabNavigator( { Home: { screen: FirstPage }, Settings: { screen: SecondPage }, }, { tabBarPosition: 'top', swipeEnabled: true, animationEnabled: true, tabBarOptions: { activeTintColor: '#FFFFFF', inactiveTintColor: '#F8F8F8', style: { backgroundColor: '#633689', }, labelStyle: { textAlign: 'center', }, indicatorStyle: { borderBottomColor: '#87B56A', borderBottomWidth: 2, }, }, } ); //making a StackNavigator to export as default const App = createStackNavigator({ TabScreen: { screen: TabScreen, navigationOptions: { headerStyle: { backgroundColor: '#633689', }, headerTintColor: '#FFFFFF', title: 'TabExample', }, }, }); //In version 2+ createAppContainer was default container //but in version 3+ you have to export it manually //In Version 2+ //export default App; //In Version 3+ export default createAppContainer(App); |
Open pages/FirstPage.js in any code editor and the Replace the code with the following code.
FirstPage.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | // Home screen import React, { Component } from 'react'; //import react in our code. import { Text, View } from 'react-native'; //import all the components we are going to use. export default class FirstPage extends React.Component { render() { return ( <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}> <Text>Home Screen</Text> </View> ); } } |
Open pages/SecondPage.js in any code editor and the Replace the code with the following code.
SecondPage.js
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | // Setting screen import React, { Component } from 'react'; //import react in our code. import { Text, View } from 'react-native'; //import all the components we are going to use. export default class SecondPage extends React.Component { render() { return ( <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}> <Text>Setting Screen</Text> </View> ); } } |
To Run the React Native App
Open the terminal again and jump into your project using.Android
IOS
