React Native Add Items to ScrollView using Loop

React Native Add Items to ScrollView using Loop

This is an example of React Native Add Items to ScrollView using Loop.  In this example, you will be having a basic idea about the loop in JavaScript. We are making a list but here we are not using any ListView instead we are making using the for loop and scroll view. We are attaching a single view containing Text on the ScrollView using the loop.

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 to Add Items to ScrollView using Loop

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


// React Native Add Items to ScrollView using Loop

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

// import all the components we are going to use
import {
} from 'react-native';

const App = () => {
  const [dataSource, setDataSource] = useState([]);

  useEffect(() => {
      .then((response) => response.json())
      .then((responseJson) => {
      .catch((error) => {
  }, []);

  const ItemView = (item, key) => {
    return (
      // Flat List Item
      <View key={key}>
          onPress={() => getItem(item)}>
            {}. {item.title}
        <ItemSeparatorView />

  const ItemSeparatorView = () => {
    return (
      // Flat List Item Separator
      <View style={styles.itemSeparatorStyle} />

  const getItem = (item) => {
    // Function for click on an item
    alert('Id : ' + + ' Title : ' + item.title);

  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
        {/* List Item as a function */}
            //Loop of JS which is like foreach loop

        {/* Passing List Item directly */}
          {, key) => (
            // key is the index of the array
            // item is the single item of the array
            <View key={key}>
              <Text style={styles.itemStyle}>
                {}. {item.title}
              <View style={styles.itemSeparatorStyle} />
        </ScrollView> */}

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'white',
  itemStyle: {
    padding: 10,
  itemSeparatorStyle: {
    height: 0.5,
    width: '100%',
    backgroundColor: '#C8C8C8',

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
