This is an Example to Show the Working of Slider in React Native. React Native Slider is a component to select a single value from a range of values. We have mostly seen slider while increasing or decreasing the volume or brightness of our phone. Here is the example of the slider which will be helpful for you to integrate slider in your app.
Under the Lean Core Project Slider has been moved to its new home @react-native-community/slider after the launch of React Native 0.59. If you are using React Native >= 0.59 then please follow the instruction for React Native >= 0.59.
To Import Slider in Code
1 | import Slider from '@react-native-community/slider' |
Render Using
1 2 3 4 5 6 | <Slider maximumValue={100} minimumValue={0} step={1} value='initial value' /> |
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 Run the following commands to create a new React Native project If you want to start a new project with a specific React Native version, you can use the --version argument: This will make a project structure with an index file named App.js in your project directory.To Make a React Native App
react-native-cli command line utility. Open the terminal and go to the workspace and runnpm install -g react-native-clireact-native init ProjectNamereact-native init ProjectName --version X.XX.Xreact-native init ProjectName --version react-native@next
Installation of Dependency
To use Slider we need to install @react-native-community/slider dependency. To install this open the terminal and jump into your project using
1 | cd ProjectName |
Run the following command to install
1 | npm install @react-native-community/slider --save |
This command will copy all the dependency into your node_module directory. –save is optional, it is just to update the @react-native-community/slider dependency in your package.json file.
CocoaPods Installation
After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use
1 | cd ios && pod install && cd .. |
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 | //This is an example code to understand Slider// import React, { Component } from 'react'; //import react in our code. //For React Native >= 0.59 import Slider from '@react-native-community/slider' import { View, Text, StyleSheet } from 'react-native'; export default class App extends Component { constructor(props) { super(props); this.state = { //Initial Value of slider sliderValue: 15 }; } render() { return ( <View style={styles.container}> {/*Text to show slider value*/} <Text style={{color: 'black'}}>Value of slider is : {this.state.sliderValue}</Text> {/*Slider with max, min, step and initial value*/} <Slider maximumValue={100} minimumValue={0} minimumTrackTintColor="#307ecc" maximumTrackTintColor="#000000" step={1} value={this.state.sliderValue} onValueChange={(sliderValue) => this.setState({ sliderValue })} /> </View> ); } } const styles = StyleSheet.create({ container: { flex: 1, padding:20, justifyContent: 'center', backgroundColor: '#ecf0f1', } }); |
To Run the React Native App
Open the terminal again and jump into your project using.cd ProjectNamereact-native run-androidreact-native run-ios (macOS only).
That was the example to show the working of Slider in React Native. If you have any doubt or you want to share something about the topic you can comment below or contact us here. The remaining components will be covered in the next article. Stay tuned!
Hope you liked it. 🙂
Installation of dependency will not work.
Wrong: npm install @react-native-community/react-native-slider –save
Correct: npm install @react-native-community/slider –save
