React Native Add Header Footer in ListView / FlatList

React Native ListView

Here is an example of React Native Add Header Footer in ListView / FlatList. As the topic name describes we will add the header and footer in FlatList. To add header and footer in FlatList we will use ListHeaderComponent and ListFooterComponent props of the FlatList same as we use ItemSeparatorComponent while adding FlatList Item Separator.

Add Header Footer in FlatList

Here is the code which we have used to add header and footer in ListView

<FlatList
  data={dataSource}
  keyExtractor={(item, index) => index.toString()}
  ItemSeparatorComponent={ItemSeparatorView}
  //Header to show above listview
  ListHeaderComponent={ListHeader}
  //Footer to show below listview
  ListFooterComponent={ListFooter}
  renderItem={ItemView}
  ListEmptyComponent={EmptyListMessage}
/>

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 command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Code to add header footer in FlatList

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

App.js

// React Native Add Header Footer in ListView / FlatList
// https://aboutreact.com/react-native-add-header-footer-in-listview/

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

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

const App = () => {
  const [dataSource, setDataSource] = useState([
    {id: 1, title: 'Button'},
    {id: 2, title: 'Card'},
    {id: 3, title: 'Input'},
    {id: 4, title: 'Avatar'},
    {id: 5, title: 'CheckBox'},
    {id: 6, title: 'Header'},
    {id: 7, title: 'Icon'},
    {id: 8, title: 'Lists'},
    {id: 9, title: 'Rating'},
    {id: 10, title: 'Pricing'},
    {id: 11, title: 'Avatar'},
    {id: 12, title: 'CheckBox'},
    {id: 13, title: 'Header'},
    {id: 14, title: 'Icon'},
    {id: 15, title: 'Lists'},
    {id: 16, title: 'Rating'},
    {id: 17, title: 'Pricing'},
  ]);

  const EmptyListMessage = ({item}) => {
    return (
      // Flat List Item
      <Text
        style={styles.emptyListStyle}
        onPress={() => getItem(item)}>
        No Data Found
      </Text>
    );
  };

  const ItemView = ({item}) => {
    return (
      // Flat List Item
      <Text
        style={styles.itemStyle}
        onPress={() => getItem(item)}>
        {item.id}
        {'.'}
        {item.title.toUpperCase()}
      </Text>
    );
  };

  const ItemSeparatorView = () => {
    return (
      // Flat List Item Separator
      <View
        style={{
          height: 0.5,
          width: '100%',
          backgroundColor: '#C8C8C8',
        }}
      />
    );
  };

  const ListHeader = () => {
    //View to set in Header
    return (
      <View style={styles.headerFooterStyle}>
        <Text style={styles.textStyle}>
            This is Header
        </Text>
      </View>
    );
  };

  const ListFooter = () => {
    //View to set in Footer
    return (
      <View style={styles.headerFooterStyle}>
        <Text style={styles.textStyle}>
            This is Footer
        </Text>
      </View>
    );
  };

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

  return (
    <SafeAreaView style={{flex: 1}}>
      <FlatList
        data={dataSource}
        keyExtractor={(item, index) => index.toString()}
        ItemSeparatorComponent={ItemSeparatorView}
        //Header to show above listview
        ListHeaderComponent={ListHeader}
        //Footer to show below listview
        ListFooterComponent={ListFooter}
        renderItem={ItemView}
        ListEmptyComponent={EmptyListMessage}
      />
    </SafeAreaView>
  );
};

const styles = StyleSheet.create({
  emptyListStyle: {
    padding: 10,
    fontSize: 18,
    textAlign: 'center',
  },
  itemStyle: {
    padding: 10,
  },
  headerFooterStyle: {
    width: '100%',
    height: 45,
    backgroundColor: '#606070',
  },
  textStyle: {
    textAlign: 'center',
    color: '#fff',
    fontSize: 18,
    padding: 7,
  },
});

export default App;

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
