Example of Tooltip in React Native for Android and IOS

Tooltip

This is an example of Tooltip in React Native for Android and IOS using react-native-walkthrough-tooltip library. The Tooltip is a common graphical user interface element. It is used to show the usability of any button or any option.

In this example, we will see how to show a tooltip on a click of a button. So let’s get started.

Import Tooltip using

import Tooltip from 'react-native-walkthrough-tooltip';

How to Show Tooltip?

<Tooltip
  animated={true}
  //(Optional) When true, tooltip will animate in/out when showing/hiding
  arrowSize={{ width: 16, height: 8 }}
  //(Optional) Dimensions of arrow bubble pointing to the highlighted element
  backgroundColor="rgba(0,0,0,0.5)"
  //(Optional) Color of the fullscreen background beneath the tooltip.
  isVisible={this.state.toolTipVisible}
  //(Must) When true, tooltip is displayed
  content={<Text>Hello! AboutReact</Text>}
  //(Must) This is the view displayed in the tooltip
  placement="bottom"
  //(Must) top, bottom, left, right, auto.
  onClose={() => this.setState({ toolTipVisible: false })}
  //(Optional) Callback fired when the user taps the tooltip
>
  <TouchableHighlight
    style={styles.touchable}
    onPress={() => this.setState({ toolTipVisible: true })}>
    <Text style={styles.touchableText}>Say Hi to AboutReact</Text>
  </TouchableHighlight>
</Tooltip>

For this example, we will make a screen with one button using TouchableHighlight and on the click of the button, we will change the visibility state of Tooltip to make it visible.

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 Dependency

To use Tooltip we need to install react-native-walkthrough-tooltip dependency.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following command to install

npm install react-native-walkthrough-tooltip --save

This command will copy all the dependency into your node_module directory.

–save is optional, it is just to update the react-native-walkthrough-tooltip dependency in your package.json file.

Code

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

App.js

/*This is an example of Tooltip in React Native*/
import React, { Component } from 'react';
//import React

import {
  Text,
  View,
  StyleSheet,
  TouchableHighlight,
  Image,
} from 'react-native';
//import Basic Component from React Native

import Tooltip from 'react-native-walkthrough-tooltip';
//Import Tooltip

export default class App extends Component {
  constructor() {
    super();
    this.state = {
      toolTipVisible: false,
      //state to control the visibility of Tooltip
    };
  }
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.largeText}>www.aboutreact.com</Text>
        <Text style={styles.largeText}>Example of Tooltip</Text>
        <Tooltip
          animated={true}
          //(Optional) When true, tooltip will animate in/out when showing/hiding
          arrowSize={{ width: 16, height: 8 }}
          //(Optional) Dimensions of arrow bubble pointing to the highlighted element
          backgroundColor="rgba(0,0,0,0.5)"
          //(Optional) Color of the fullscreen background beneath the tooltip.
          isVisible={this.state.toolTipVisible}
          //(Must) When true, tooltip is displayed
          content={<Text>Hello! AboutReact</Text>}
          //(Must) This is the view displayed in the tooltip
          placement="bottom"
          //(Must) top, bottom, left, right, auto.
          onClose={() => this.setState({ toolTipVisible: false })}
          //(Optional) Callback fired when the user taps the tooltip
        >
          <TouchableHighlight
            style={styles.touchable}
            onPress={() => this.setState({ toolTipVisible: true })}>
            <Text style={styles.touchableText}>Say Hi to AboutReact</Text>
          </TouchableHighlight>
        </Tooltip>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignContent: 'center',
    textAlign: 'center',
    paddingTop: 30,
    backgroundColor: '#307ecc',
    padding: 16,
  },
  touchable: {
    width: '100%',
    height: 40,
    padding: 10,
    backgroundColor: '#f5821f',
    marginTop: 30,
  },
  touchableText: {
    color: 'white',
    textAlign: 'center',
  },
  largeText: {
    color: 'white',
    textAlign: 'center',
    fontSize: 20,
    marginTop: 10,
  },
});

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

react-native run-ios (macOS only).
