Dynamically Change React Navigation Value – Update navigationOptions

Update navigationOptions in React Navigation

This is an Example to Dynamically Change React Navigation Value – Update navigationOptions. You will see how to change the Navigation Option values dynamically from the click of a button or using a state. This can be easily done by setting the navigation params.

This example will be helpful if you want to change the navigation options like navigation text, navigation text color, background color, etc on a click of a button or on some certain condition. For example, if you are planning to make an application in which the user can change the theme of the application. Here is an example for you to Dynamically Change React Navigation Value.

To Dynamically Change navigationOptions Value

We can change the navigation bar title, background color and text color from the click of any button by setting the navigation options.

// To change navigation options
navigation.setOptions({
  title: 'Yellow Header',
  headerStyle: {
    backgroundColor: 'yellow', //Set Header color
  },
  headerTintColor: 'black', //Set Header text color
  headerTitleStyle: {
    fontWeight: 'bold', //Set Header text style
  },
});

In this example, we will use react-navigation to make the navigation bar on the top of the screen and then with the help of three different buttons we will change the color of the navigation bar. So let’s get started.

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.

Installation of Dependencies

For navigation we need to add react-navigation and other supporting dependencies.

To install the dependencies open the terminal and jump into your project

cd ProjectName

1. Install react-navigation

npm install @react-navigation/native --save

2. Other supporting libraries react-native-gesture-handler, react-native-reanimated, react-native-screens and react-native-safe-area-context and @react-native-community/masked-view

npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view --save

3. For the Stack Navigator install

npm install @react-navigation/stack --save

Note: When you use a navigator (such as stack navigator), you’ll need to follow the installation instructions of that navigator for any additional dependencies. If you’re getting an error “Unable to resolve module”, you need to install that module in your project.

You might get warnings related to peer dependencies after installation. They are usually caused by incorrect version ranges specified in some packages. You can safely ignore most warnings as long as your app builds.

CocoaPods Installation

Please use the following command to install CocoaPods

npx pod-install ios

To finalize the installation of react-native-gesture-handler, add the following at the top (make sure it’s at the top and there’s nothing else before it) of your entry files, such as index.js or App.js:

import 'react-native-gesture-handler';

Note: If you skip this step, your app may crash in production even if it works fine in development.

Project File Structure

To start with this example you need to create a directory named pages in your project and create a file HomeActivity.js in it.

Code

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

App.js

// Dynamically Change React Navigation Value – Update navigationOptions
// https://aboutreact.com/dynamically-change-navigationoptions-value/

import 'react-native-gesture-handler';

import React from 'react';

import {NavigationContainer} from '@react-navigation/native';
import {createStackNavigator} from '@react-navigation/stack';

import HomeActivity from './pages/HomeActivity';

const Stack = createStackNavigator();

const App = () => {
  return (
    <NavigationContainer>
      <Stack.Navigator initialRouteName="HomeActivity">
        <Stack.Screen
          name="HomeActivity"
          component={HomeActivity}
        />
      </Stack.Navigator>
    </NavigationContainer>
  );
};

export default App;

Open pages/HomeActivity.js in any code editor and replace the code with the following code

HomeActivity.js

// Dynamically Change React Navigation Value – Update navigationOptions
// https://aboutreact.com/dynamically-change-navigationoptions-value/

import React from 'react';
import {
  SafeAreaView,
  StyleSheet,
  Text,
  TouchableOpacity,
  View,
} from 'react-native';

const HomeActivity = ({navigation, route}) => {
  const changeHeaderYellow = () => {
    // Function to change navigation options
    navigation.setOptions({
      title: 'Yellow Header',
      headerStyle: {
        backgroundColor: 'yellow', //Set Header color
      },
      headerTintColor: 'black', //Set Header text color
      headerTitleStyle: {
        fontWeight: 'bold', //Set Header text style
      },
    });
  };

  const changeHeaderPink = () => {
    // Function to change navigation options
    navigation.setOptions({
      title: 'Pink Header',
      headerStyle: {
        backgroundColor: 'pink', //Set Header color
      },
      headerTintColor: 'black', //Set Header text color
      headerTitleStyle: {
        fontWeight: 'bold', //Set Header text style
      },
    });
  };

  const changeHeaderOrange = () => {
    // Function to change navigation options
    navigation.setOptions({
      title: 'Orange Header',
      headerStyle: {
        backgroundColor: 'orange', //Set Header color
      },
      headerTintColor: 'black', //Set Header text color
      headerTitleStyle: {
        fontWeight: 'bold', //Set Header text style
      },
    });
  };

  return (
    <SafeAreaView style={{flex: 1, backgroundColor: 'white'}}>
      <View style={styles.container}>
        <Text style={styles.header}>
          Dynamically Change React Navigation Value
          {'\n'}
          Update navigation Options
        </Text>

        {/* Change header color to yellow */}
        <TouchableOpacity
          onPress={changeHeaderYellow}
          activeOpacity={0.7}
          style={styles.buttonStyle}>
          <Text style={styles.textStyle}>APPLY YELLOW COLOR</Text>
        </TouchableOpacity>

        {/* Change header color to pink */}
        <TouchableOpacity
          onPress={changeHeaderPink}
          activeOpacity={0.7}
          style={styles.buttonStyle}>
          <Text style={styles.textStyle}>APPLY PINK COLOR</Text>
        </TouchableOpacity>

        {/* Change header color to orange */}
        <TouchableOpacity
          onPress={changeHeaderOrange}
          activeOpacity={0.7}
          style={styles.buttonStyle}>
          <Text style={styles.textStyle}>APPLY ORANGE COLOR</Text>
        </TouchableOpacity>
      </View>
      <Text style={{textAlign: 'center', color: 'grey'}}>
        www.aboutreact.com
      </Text>
    </SafeAreaView>
  );
};

export default HomeActivity;

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    padding: 16,
  },
  header: {
    fontSize: 25,
    textAlign: 'center',
    marginVertical: 16,
  },
  buttonStyle: {
    width: '100%',
    height: 40,
    padding: 10,
    backgroundColor: '#808080',
    borderRadius: 2,
    marginTop: 12,
  },
  textStyle: {
    color: '#fff',
    textAlign: 'center',
  },
});

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
