React Native Modal – How to Show a Modal in React Native

React Native Modal

This post will give you an idea about How to Show a Modal in React Native for Android and IOS. React Native Modal is a component to present content above an enclosing view. This is supported by Android and IOs both. Modal contains its own view which is visible when we open the modal. Here is a small example to show how can we make modal in our React Native App.

To Import Modal in Code

import { Modal } from 'react-native'

Render Using

<Modal>All views inside the modal</Modal>

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.

Code

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

App.js

//React Native Modal
//https://aboutreact.com/react-native-modal/

//import React in our code
import React, {useState} from 'react';

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

const App = () => {
  const [showModal, setShowModal] = useState(false);

  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
        <Modal
          animationType={'slide'}
          transparent={false}
          visible={showModal}
          onRequestClose={() => {
            console.log('Modal has been closed.');
          }}>
          {/*All views of Modal*/}
          {/*Animation can be slide, slide, none*/}
          <View style={styles.modal}>
            <Text style={styles.text}>Modal is open!</Text>
            <Button
              title="Click To Close Modal"
              onPress={() => {
                setShowModal(!showModal);
              }}
            />
          </View>
        </Modal>
        {/*Button will change state to true and view will re-render*/}
        <Button
          title="Click To Open Modal"
          onPress={() => {
            setShowModal(!showModal);
          }}
        />
      </View>
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    backgroundColor: '#ecf0f1',
    marginTop: 30,
  },
  modal: {
    flex: 1,
    alignItems: 'center',
    backgroundColor: '#00ff00',
    padding: 100,
  },
  text: {
    color: '#3f2949',
    marginTop: 10,
  },
});

export default App;

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
