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 user 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.

Here is the list of some keyboardType:

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

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.

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

App.js

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
react-native run-ios (macOS only).
