In this chapter, we will show you how to create a list in React Native. We will import List in our Home component and show it on screen.

App.js

import React from ''react''
import List from ''./List.js''

const App = () => {
   return (
      <List />
   )
}
export default App

To create a list, we will use the map() method. This will iterate over an array of items, and render each one.

List.js

import React, { Component } from ''react''
import { Text, View, TouchableOpacity, StyleSheet } from ''react-native''
   
class List extends Component {
   state = {
      names: [
         {
            id: 0,
            name: ''Ben'',
         },
         {
            id: 1,
            name: ''Susan'',
         },
         {
            id: 2,
            name: ''Robert'',
         },
         {
            id: 3,
            name: ''Mary'',
         }
      ]
   }
   alertItemName = (item) => {
      alert(item.name)
   }
   render() {
      return (
         <View>
            {
               this.state.names.map((item, index) => (
                  <TouchableOpacity
                     key = {item.id}
                     style = {styles.container}
                     onPress = {() => this.alertItemName(item)}>
                     <Text style = {styles.text}>
                        {item.name}
                     </Text>
                  </TouchableOpacity>
               ))
            }
         </View>
      )
   }
}
export default List

const styles = StyleSheet.create ({
   container: {
      padding: 10,
      marginTop: 3,
      backgroundColor: ''#d9f9b1'',
      alignItems: ''center'',
   },
   text: {
      color: ''#4f603c''
   }
})

When we run the app, we will see the list of names.

You can click on each item in the list to trigger an alert with the name.
