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
1 | import Tooltip from 'react-native-walkthrough-tooltip'; |
To Show Tooltip
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | <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 1 buttons using TouchableHighlight and on the click of the button we will change the visibility state of Tootip 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 thereact-native-cli command line utility.
Open the terminal and go to the workspace and runnpm install -g react-native-clireact-native init ProjectNameInstallation 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
1 | cd ProjectName |
Run the following command to install
1 | 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.
Now Open App.js in any code editor and replace the code with the following code.
App.js

To Run the React Native App
Open the terminal again and jump into your project using.cd ProjectNamereact-native run-androidreact-native run-ios (macOS only).Android
