React Native Bottom Action Menu

Bottom Action Menu

This is an Example to make React Native Bottom Action Menu. To make Bottom Action Menu, we are going to use ActionSheet component from react-native-actionsheet library.

This can be mostly seen by the IOS developers as it looks like a default select option in IOS. With the help of Bottom Action Menu, you can provide the facility to select from multiple options.

How to use the ActionSheet Component?

<ActionSheet
  ref={o => (this.ActionSheet = o)}
  //Title of the Bottom Sheet
  title={'Which one do you like ?'}
  //Options Array to show in bottom sheet
  options={optionArray}
  //Define cancel button index in the option array
  //this will take the cancel option in bottom and will highlight it
  cancelButtonIndex={4}
  //If you want to highlight any specific option you can use below prop with option index
  destructiveButtonIndex={1}
  onPress={index => {
    //Clicking on the option will give you the index of the option clicked
    alert(optionArray[index]);
  }}
/>

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 ActionSheet you need to install react-native-actionsheet package. To install this

Open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-actionsheet --save

This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update the react-native-action sheet dependency in your package.json file.

Code for Bottom Action Menu

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

App.js

//This is an example code for React Native Bottom Action Sheet//
import React from 'react';
//import react in our code.
import { View, Button } from 'react-native';
// import all basic components
import ActionSheet from 'react-native-actionsheet';
// import ActionSheet
export default class Demo extends React.Component {
  showActionSheet = () => {
    //To show the Bottom ActionSheet
    this.ActionSheet.show();
  };
  render() {
    //Options to show in bottom action sheet. Option Array can be dynamic too
    var optionArray = [
      'Option 1',
      'Option 2',
      'Option 3',
      'Option 4',
      'Cancel',
    ];
    return (
      <View style={{ padding: 25, flex: 1, justifyContent: 'center' }}>
        <Button
          onPress={this.showActionSheet}
          title="Open Buttom ActionSheet"
        />
        <ActionSheet
          ref={o => (this.ActionSheet = o)}
          //Title of the Bottom Sheet
          title={'Which one do you like ?'}
          //Options Array to show in bottom sheet
          options={optionArray}
          //Define cancel button index in the option array
          //this will take the cancel option in bottom and will highlight it
          cancelButtonIndex={4}
          //If you want to highlight any specific option you can use below prop
          destructiveButtonIndex={1}
          onPress={index => {
            //Clicking on the option will give you the index of the option clicked
            alert(optionArray[index]);
          }}
        />
      </View>
    );
  }
}

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).
