React Native - ListView


Previous Page Next Page  

In this chapter, we will show you how to create a pst 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 pst, 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 ,
      apgnItems:  center ,
   },
   text: {
      color:  #4f603c 
   }
})

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

ListView

You can cpck on each item in the pst to trigger an alert with the name.
