How to set onPress on a View in React Native

In this post, we will see How to set onPress on a View in React Native. While working with React Native components we need to set onPress on different situations to do that we have to surround it with the React Native Touchables but what if we can set onPress on the View container itself. You can do this using onStartShouldSetResponder(This will work only after React Native version -> 55.3). So let’s see the example.

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

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 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).
