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 init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

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

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

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

/*This is an example of Segmented Control Tab in React Native*/
import React, { Component } from 'react';
//Import React

import { StyleSheet, Text, View } from 'react-native';
//Import Basic React Native Component

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

class App extends Component {
  constructor() {
    super();
    this.state = {
      selectedIndex: 0,
      //Default selected Tab Index for single select SegmentedControlTab
      selectedIndices: [0],
      //Default selected Tab Indexes for multi select SegmentedControlTab
      customStyleIndex: 0,
      //Default selected Tab Indexes for cusatom SegmentedControlTab
    };
  }

  handleSingleIndexSelect = (index: number) => {
    //handle tab selection for single Tab Selection SegmentedControlTab
    this.setState(prevState => ({ ...prevState, selectedIndex: index }));
  };

  handleMultipleIndexSelect = (index: number) => {
    //handle tab selection for multi Tab Selection SegmentedControlTab
    const { selectedIndices } = this.state;
    if (selectedIndices.includes(index)) {
      //if included in the selected array then remove
      this.setState(prevState => ({
        ...prevState,
        selectedIndices: selectedIndices.filter(i => i !== index),
      }));
    } else {
      //if not included in the selected array then add
      this.setState(prevState => ({
        ...prevState,
        selectedIndices: [...selectedIndices, index],
      }));
    }
  };

  handleCustomIndexSelect = (index: number) => {
    //handle tab selection for custom Tab Selection SegmentedControlTab
    this.setState(prevState => ({ ...prevState, customStyleIndex: index }));
  };

  render() {
    const { selectedIndex, selectedIndices, customStyleIndex } = this.state;
    return (
      <View style={styles.container}>
        {/* Simple Segmented Control*/}
        <Text style={styles.headerText}>
          Simple Segmented Control with Single Selection
        </Text>
        <SegmentedControlTab
          values={['Segment One', 'Segment two']}
          selectedIndex={selectedIndex}
          tabStyle={styles.tabStyle}
          activeTabStyle={styles.activeTabStyle}
          onTabPress={this.handleSingleIndexSelect}
        />
        <View style={styles.Seperator} />

        {/* Additional badges in Simple Segmented Control*/}
        <Text style={styles.headerText}>
          Simple Segmented Control with Single Selection + Badges
        </Text>
        <SegmentedControlTab
          badges={[12, 24]}
          values={['Segment One', 'Segment two']}
          selectedIndex={selectedIndex}
          onTabPress={this.handleSingleIndexSelect}
        />
        <View style={styles.Seperator} />

        {/* Simple Segmented Control with multi Select*/}
        <Text style={styles.headerText}>
          Simple Segmented Control with Multiple Selection
        </Text>
        <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
        />
        <View style={styles.Seperator} />
        <Text style={styles.headerText}>
          Custom segmented control with custom styles
        </Text>

        {/* Simple Segmented with Custom Styling*/}
        <SegmentedControlTab
          values={['one', 'two']}
          selectedIndex={customStyleIndex}
          onTabPress={this.handleCustomIndexSelect}
          borderRadius={0}
          tabsContainerStyle={{ height: 50, backgroundColor: '#F2F2F2' }}
          tabStyle={{

        />
        {customStyleIndex === 0 && (
          <Text style={styles.tabContent}> Tab one</Text>
        )}
        {customStyleIndex === 1 && (
          <Text style={styles.tabContent}> Tab two</Text>
        )}
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: 'white',
    padding: 10,
  },
  headerText: {

  tabContent: {
    color: '#444444',
    fontSize: 18,
    margin: 24,

  Seperator: {
    marginHorizontal: -10,
    alignSelf: 'stretch',
    borderTopWidth: 1,
    borderTopColor: '#888888',
    marginTop: 24,

  activeTabStyle: {
    backgroundColor: '#D52C43',
  },
});

export default App;

  1. This was really helpful thank you!

    I have been looking for code samples like this and couldn’t find them anywhere – not even in the official docs for the react-native-segmented-control-tab github.

    I was able to successfully set up multi-select using this code sample. Thank you for posting
