React Native Radio Button
A radio button is a type of button which allows the user to select only one option from a set of options.
In React Native, a radio button is represented by the RadioButton component.
The RadioButton component is a subclass of the TouchableOpacity component.
It has a text property which specifies the text displayed on the button.
It also has a value property which specifies the value of the button.
The value of a radio button can be changed by setting the value property to a new value.
The following example demonstrates the use of the RadioButton component:
import React, { Component } from ‘react’;
import { RadioButton } from ‘react-native’;
class App extends Component {
constructor() {
super();
this.state = {
radioButton: ‘default’
};
}
render() {
return (
value=’1′
text=’One’
/>
value=’2′
text=’Two’
/>
value=’3′
text=’Three’
/>
);
}
}
The following example demonstrates the use of the onChange event handler of the RadioButton component:
import React, { Component } from ‘react’;
import { RadioButton } from ‘react-native’;
class App extends Component {
constructor() {
super();
this.state = {
radioButton: ‘default’
};
}
render() {
return (
value=’1′
text=’One’
onChange={(value) => this.setState({
radioButton: value
})}
/>
value=’2′
text=’Two’
onChange={(value) => this.setState({
radioButton: value
})}
/>
value=’3′
text=’Three’
onChange={(value) => this.setState({
radioButton: value
})}
/>
);
}
}
The following example demonstrates the use of the onPress event handler of the RadioButton component:
import React, { Component } from ‘react’;
import { RadioButton } from ‘react-native’;
class App extends Component {
constructor() {
super();
this.state = {
radioButton: ‘default’
};
}
render() {
return (
value=’1′
text=’One’
onPress={() => this.setState({
radioButton: ‘1’
})}
/>
value=’2′
text=’Two’
onPress={() => this.setState({
radioButton: ‘2’
})}
/>
value=’3′
text=’Three’
onPress={() => this.setState({
radioButton: ‘3’
})}
/>
);
}
}

Radio buttons are a common user interface control. They allow the user to make a single choice from a list of options.
React Native does not have a built-in radio button control, but there are several libraries that provide this functionality.
The React Native Radio Button library by James Kyle is a popular option. It allows you to create a radio button control with a single line of code.
The library also includes a wide range of customization options, so you can create a control that looks and behaves the way you want.
A radio button is a type of input control that allows a user to select only one option from a set of options.
In React Native, you can create a radio button by using the RadioGroup component.
The RadioGroup component is a container for a group of radio buttons. It renders a set of radio buttons in a row, and allows only one button to be selected at a time.
To create a RadioGroup component, you first need to create a RadioButton component for each option. Then, you need to wrap the RadioButton components in a RadioGroup component.
Here’s an example:
import React, { Component } from ‘react’;
import { RadioGroup, RadioButton } from ‘react-native’;
class RadioButtons extends Component {
render() {
return (
Option 1
Option 2
Option 3
);
}
}
You can also use the onPress prop to specify a function to be executed when the button is pressed.
For example, the following code will print “Option 1” when the Option 1 button is pressed:
import React, { Component } from ‘react’;
import { RadioGroup, RadioButton } from ‘react-native’;
class RadioButtons extends Component {
render() {
return (
console.log(‘Option 1’)}>Option 1
console.log(‘Option 2’)}>Option 2
console.log(‘Option 3’)}>Option 3
);
}
}
Radio buttons are a type of input control used to allow the user to select only one option from a given set. In React, radio buttons can be implemented by using the component.
The component is used to wrap a set of radio buttons. It takes two props – options and checked. The options prop is used to specify the options that will be available to the user, while the checked prop is used to specify the default option.
To create a radio button, you need to use the component. The component takes two props – name and value. The name prop is used to specify the name of the button, while the value prop is used to specify the value that will be stored when the button is checked.
Here’s an example of how to use the and components:
In the code above, the component will create a set of two radio buttons, “option1” and “option2”. The “option1” button will be checked by default.
To create a radio button, you need to use the component. The component takes two props – name and value. The name prop is used to specify the name of the button, while the value prop is used to specify the value that will be stored when the button is checked.
Here’s an example of how to use the component:
In the code above, the component will create a radio button with the name “option1” and the value “1”.
There may be times when you want to disable a radio button in React Native. Perhaps you have a list of options and you only want one of them to be available at a time. In this article, we’ll show you how to do that.
The first thing you need to do is import the RadioGroup component from the react-native-radio-group module.
Next, create a RadioGroup component and add the options you want to it.
Then, set the disabled property of the RadioGroup to true.
Now, when you try to select a radio button that’s disabled, it won’t be active.
How do I create a checkbox in react-native?
There are a few ways to create a checkbox in React Native. In this article, we will explore two of the most common ways.
The first way is to use the component.
To use the component, you first need to import it into your project.
Next, you need to create a component and give it a name.
Then, you need to set the checked property to true if you want the checkbox to be checked by default, or false if you want it to be unchecked.
Finally, you need to add the component to your React Native app.
Here is an example of how to use the component:
import React, { Component } from ‘react’;
import { Checkbox } from ‘react-native’;
class App extends Component {
render() {
return (
);
}
}
The second way to create a checkbox in React Native is to use the component.
To use the component, you first need to import it into your project.
Next, you need to create a component and give it a name.
Then, you need to set the onChange property to the name of a function that will be called when the checkbox is checked or unchecked.
Finally, you need to add the component to your React Native app.
Here is an example of how to use the component:
import React, { Component } from ‘react’;
import { Switch } from ‘react-native’;
class App extends Component {
render() {
return (
this.checkbox1Changed()} />
);
}
}
function checkbox1Changed() {
console.log(‘The checkbox has been changed!’);
}
Adding a toggle button in react-native is a two-step process:
1. Adding the ToggleButton component
2. Adding the onToggle handler
The ToggleButton component is a simple wrapper around the TouchableOpacity component. It renders a button that can be toggled on and off.
To add a ToggleButton component, first import it from the React Native library:
import { ToggleButton } from “react-native”;
Then, add it to your component hierarchy:
render() {
return (
);
}
The onToggle handler is a function that gets called when the toggle button is clicked. It takes two arguments: the current state of the toggle button, and a function to call when the toggle button is clicked.
To add the onToggle handler, first import it from the React Native library:
import { onToggle } from “react-native”;
Then, add it to your component:
componentDidMount() {
onToggle(
true,
() => {
// do something
}
);
}
Now, when the toggle button is clicked, the function will be called.
How do I use a radio group in react-native?
React Native Radio Groups let you display a list of radio buttons, where only one button can be selected at a time.
To use a Radio Group, you’ll need to first create a RadioGroup component:
class MyComponent extends Component {
render() {
return (
);
}
}
The value attribute of each RadioButton defines the text that will be displayed on the button.
You can then use the RadioGroup in your code by calling the onChange event:
MyComponent
.onChange(
() => {
console.log(“The selected button is: ” + this.props.value);
}
)
When a user selects a button in the Radio Group, the onChange event will be triggered and the value of the selected button will be logged to the console.
