Example to Get Only Numeric Value From TextInput in React Native


This is an Example to Get Only Numeric Value From TextInput in React Native. This is used in many cases like when you have to take the mobile number of users you need the number to be inserted. Using this will open the Numeric Keyboard when the user clicks on the TextInput. We are going to use the TextInput prop numeric to get only Numeric value.

As the number can be decimal so in the numeric keyboard user can enter a dot(.) also if you want a pure numeric keyboard with no dot(.) then you can use number-pad instead of numeric.

List of Keyboard Type

Here is the list of some keyboard type:

  1. default
  2. number-pad
  3. decimal-pad
  4. numeric
  5. email-address
  6. phone-pad

Get Only Numeric Value Using

  placeholder="Enter Numeric Values Only"
  numeric value   // This prop makes the input to get numeric only 
  keyboardType={'numeric'} // This prop help to open numeric keyboard

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 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.


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


//Example to Get Only Numeric Value From TextInput in React Native

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

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

const App = () => {
  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
          placeholder="Enter Numeric Values Only"

const styles = StyleSheet.create({
  container: {
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#ffffff',
    flex: 1,
  textInputStyle: {
    width: 250,
    backgroundColor: '#dde8c9',
    padding: 16,

export default App;

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
