Segmented Control Tab in React Native for Android and iOS

React Native Segmented Control Tab

This is an example of the Segmented Control Tab in React Native for Android and iOS using react-native-segmented-control-tab. iOS developers know what Segmented Control Tab is but if you are coming from an Android development background and have no idea what Segmented Control Tab is, then just imagine a Tab View in Android. Segmented Control Tab is the same as Tab in Android but without Swipe to change Tab feature.

Types of Segmented Control Tab

It is used as a navigator or to show multiple screens on a single screen. There are 4 Types of Segmented Control Tab that we are going to cover:

1. Simple Segmented Control Tab
2. Simple Segmented Control Tab with Badges
3. Multi-Select Simple Segmented Control Tab
4. Custom Styling Segmented Control Tab

In this example, we will see how to make a Segmented Control Tab, how to select any tab as default tab, how to call any handler when tab changes, how to control a tab selection using state. So let’s get started.

Import Segmented Control Tab using

to import Segmented Control Tab we use

import
  SegmentedControlTab
from 'react-native-segmented-control-tab';

To make Simple Segmented Control Tab

{/* Simple Segmented Control*/}
<SegmentedControlTab
  values={['Segment One', 'Segment two']}
  selectedIndex={selectedIndex}
  tabStyle={styles.tabStyle}
  activeTabStyle={styles.activeTabStyle}
  onTabPress={this.handleSingleIndexSelect}
/>

Simple Segmented Control Tab with Badges

{/* Additional badges in Simple Segmented Control*/}
<SegmentedControlTab
  badges={[12, 24]}
  values={['Segment One', 'Segment two']}
  selectedIndex={selectedIndex}
  onTabPress={this.handleSingleIndexSelect}
/>

Multi-Select Simple Segmented Control Tab

{/* Simple Segmented Control with multi Select*/}
<SegmentedControlTab
  values={['Segment One', 'Segment two', 'Segment Three']}
  multiple
  //You need to add the multiple as conpared to single select
  selectedIndices={selectedIndices}
  //pass the selected index array for the default selection
  onTabPress={this.handleMultipleIndexSelect}
  //Pushing the selected option index in selected item array
/>

Custom Styling Segmented Control Tab

{/* Simple Segmented with Custom Styling*/}
<SegmentedControlTab
  values={['one', 'two']}
  selectedIndex={customStyleIndex}
  onTabPress={this.handleCustomIndexSelect}
  borderRadius={0}
  tabsContainerStyle={{ height: 50, backgroundColor: '#F2F2F2' }}
  tabStyle={{
    backgroundColor: '#F2F2F2',
    borderWidth: 0,
    borderColor: 'transparent',
  }}
  activeTabStyle={{ backgroundColor: 'white', marginTop: 2 }}
  tabTextStyle={{ color: '#444444', fontWeight: 'bold' }}
  activeTabTextStyle={{ color: '#888888' }}
/>

For this example, we will make a screen with 4 different types of Segmented Control Tab. Each Tab have different property. This 4 Segmented Control Tab includes Simple Segmented Control, Additional badges in Simple Segmented Control, Simple Segmented Control with multi Select, Simple Segmented with Custom Styling.

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 command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use SegmentedControlTab we need to install react-native-segmented-control-tab dependency.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following command to install

npm install react-native-segmented-control-tab --save

This command will copy all the dependency into your node_module directory.

–save is optional, it is just to update the react-native-segmented-control-tab dependency in your package.json file.

Code

Now Open App.js in any code editor and replace the code with the following code

App.js

// Segmented Control Tab in React Native for Android and iOS
// https://aboutreact.com/react-native-segmented-control-tab/

// import React in our code
import React, {useState} from 'react';

// import all the components we are going to use
import {
  SafeAreaView,
  StyleSheet,
  Text,
  View
} from 'react-native';

// importing Segmented Control Tab
import 
  SegmentedControlTab 
from 'react-native-segmented-control-tab';

const App = () => {
  // For single select SegmentedControlTab
  const [selectedIndex, setSelectedIndex] = useState(0);
  // For multi select SegmentedControlTab
  const [selectedIndices, setSelectedIndices] = useState([0]);
  // For custom SegmentedControlTab
  const [customStyleIndex, setCustomStyleIndex] = useState(0);

  const handleSingleIndexSelect = (index) => {
    // For single Tab Selection SegmentedControlTab
    setSelectedIndex(index);
  };

  const handleMultipleIndexSelect = (index) => {
    // For multi Tab Selection SegmentedControlTab
    if (selectedIndices.includes(index)) {
      // Included in the selected array then remove
      setSelectedIndices(
        selectedIndices.filter((i) => i !== index)
      );
    } else {
      // Not included in the selected array then add
      setSelectedIndices([...selectedIndices, index]);
    }
  };

  const handleCustomIndexSelect = (index) => {
    // Tab selection for custom Tab Selection
    setCustomStyleIndex(index);
  };

  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        {/* Simple Segmented Control*/}

          selectedIndex={selectedIndex}
          tabStyle={styles.tabStyle}
          activeTabStyle={styles.activeTabStyle}
          onTabPress={handleSingleIndexSelect}
        />
        <View style={styles.seperator} />

        {/* Additional badges in Simple Segmented Control*/}
        <Text style={styles.headerText}>
          Simple Segmented Control with Single Selection + Badges
        </Text>
        <SegmentedControlTab

          values={['Segment One', 'Segment two']}
          selectedIndex={selectedIndex}
          onTabPress={handleSingleIndexSelect}
        />
        <View style={styles.seperator} />

        {/* Simple Segmented Control with multi Select*/}
        <Text style={styles.headerText}>

});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
