Explain ReactNative SwitchSelector Component

SwitchSelector component is similar to a radio toggle button. It allows you to select with more than 2 values.

To work with SwitchSelector you have to install the package as shown below −

npm i react-native-switch-selector --save-dev

The basic SwitchSelector looks as follows −

<SwitchSelector
   106
   React Native – Q&A
   options={youroptions}
   initial={0}
   onPress={value => console.log(`value selected is : ${value}`)}
/>

Here are some important properties of SwitchSelector −

Example: Working of SwitchSelector

To work with SwitchSelector we have to import the component as follows −

import SwitchSelector from "react-native-switch-selector";

Inside the SwitchSelector we won’t to display two options: Female/Male.

In the example, we are making use of female and male images and the same is used in the options array.

let male = require('C:/myfirstapp/myfirstapp/assets/male.png');
let female = require('C:/myfirstapp/myfirstapp/assets/female.png');
const images = {
   "female": female,
   "male": male,
};
const options =[
   { label: "Female", value: "f", imageIcon: images.female },
   { label: "Male", value: "m", imageIcon: images.male }
];

The SwitchSelector looks as follows −

<SwitchSelector
   initial={0}
   onPress={value => this.setState({ gender: value })}
   textColor='#ccceeaa'
   selectedColor='#7a44cf'
   buttonColor='#ccc'
   borderColor='#ccc'
   hasPadding
   options={options}
/>

Here is the full code of SwitchSelector −

Example

import React, { Component } from 'react';
import { StyleSheet, SafeAreaView } from 'react-native';
import SwitchSelector from "react-native-switch-selector";
let male = require('C:/myfirstapp/myfirstapp/assets/male.png');
let female = require('C:/myfirstapp/myfirstapp/assets/female.png');
const images = {
   "female": female,
   "male": male,
};
const options =[
   { label: "Female", value: "f", imageIcon: images.female },
   { label: "Male", value: "m", imageIcon: images.male }
];
export default class MySwitchSelectorComponent extends Component {
   render() {
      return (
         <SafeAreaView style={styles.container}>
            <SwitchSelector
               initial={0}
                  onPress={value => this.setState({ gender: value })}
                  textColor='#ccceeaa'
                  selectedColor='#7a44cf'
                  buttonColor='#ccc'
                  borderColor='#ccc'
                  hasPadding
                  options={options}
            />
         </SafeAreaView>
      )
   }
}
const styles = StyleSheet.create({
   container: {
      flex: 1,
      alignItems: "center",
      justifyContent: "center"
   },
});

Output

The output is as follows −

Example 2: SwitchSelector with three options

In the example below, we have used three options −

const options =[
   { label: "First", value: "a"},
   { label: "Second", value: "b" } ,
   { label: "Third", value: "c" }
];

The full code to display three options is as follows −

Example

import React, { Component } from 'react';
import { StyleSheet, SafeAreaView } from 'react-native';
import SwitchSelector from "react-native-switch-selector";
const options =[
   { label: "First", value: "a"},
   { label: "Second", value: "b" } ,
   { label: "Third", value: "c" }
];
export default class MySwitchSelectorComponent extends Component {
   render() {
      return (
         <SafeAreaView style={styles.container}>
            <SwitchSelector
               initial={0}
               onPress={value => this.setState({ gender: value })}
               textColor='#ccceeaa'
               selectedColor='#7a44cf'
               buttonColor='#ccc'
               borderColor='#ccc'
               fontSize='30'
               hasPadding
               options={options}
            />
         </SafeAreaView>
      )
   }
}
const styles = StyleSheet.create({
   container: {
      flex: 1
   }
});
