React Native Vibration | Start Stop Device Vibration in React Native

React Native Vibration

React Native Start Stop Device Vibration includes the way you can start and start the vibration on a button click. you can vibrate the device when you want to give feedback on any action performed by the user. For example, if you use any keyboard you can generate small vibration so that user come to know that some action was performed.

We will use Vibration component to vibrate the Device. It is one of the basic components provided by the React native.

Note: We will suggest running this example in the real device as you can’t feel the vibration in Virtual Devices.

To Import Vibration

import { Vibration} from 'react-native'

Start the Vibration Using

Vibration.vibrate(DURATION)

Stop the Vibration Using

Vibration.cancel()

In this example, We will start and stop vibration on a button click. So let’s get started.

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.

Android Permission

Android apps should request the android.permission.VIBRATE permission by adding following permission to AndroidManifest.xml.

<uses-permission android:name="android.permission.VIBRATE"/>

Code

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

App.js

// React Native Vibration | Start Stop Device Vibration in React Native
// https://aboutreact.com/react-native-start-stop-device-vibration-on-button-click/

// import React in our code
import React from 'react';

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

//Duration of the vibration
const DURATION = 1000;

const App = () => {
  const startVibration = () => {
    //To start the vibration for the defined Duration
    Vibration.vibrate(DURATION);
  };

  const stopVibration = () => {
    //To Stop the vibration
    Vibration.cancel();
  };

  return (
    <SafeAreaView style={styles.container}>
      <View>
        <Text style={styles.titleText}>
          React Native Vibration |
          Start Stop Device Vibration in React Native
        </Text>
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={startVibration}>
          <Text style={styles.buttonTextStyle}>
            Start Vibration
          </Text>
        </TouchableOpacity>
        <TouchableOpacity
          activeOpacity={0.7}
          style={styles.buttonStyle}
          onPress={stopVibration}>
          <Text style={styles.buttonTextStyle}>
            Stop Vibration
          </Text>
        </TouchableOpacity>
      </View>
    </SafeAreaView>
  );
};

export default App;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: 'white',
    padding: 10,
    justifyContent: 'center',
  },
  titleText: {
    fontSize: 22,
    textAlign: 'center',
    fontWeight: 'bold',
  },
  buttonStyle: {
    justifyContent: 'center',
    marginTop: 15,
    padding: 10,
    backgroundColor: '#8ad24e',
    marginRight: 2,
    marginLeft: 2,
  },
  buttonTextStyle: {
    color: '#fff',
    textAlign: 'center',
  },
});

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

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

react-native run-android

or on the iOS Simulator by running (macOS only)

react-native run-ios
