# RadioButton

A Jetpack Compose RadioButton component for single-selection controls.
Android, Included in Expo Go

> For the complete documentation index, see [llms.txt](/llms.txt). Use this file to discover all available pages.

A radio button component for selecting a single option from a set. Maps to the official Jetpack Compose [RadioButton](https://developer.android.com/develop/ui/compose/components/radio-button) API.

## Installation

```sh
npx expo install @expo/ui
```

If you are installing this in an [existing React Native app](/bare/overview), make sure to [install `expo`](/bare/installing-expo-modules) in your project.

## Usage

### Basic radio button

A standalone radio button with an `onClick` handler.

```tsx
import { useState } from 'react';
import { Host, RadioButton } from '@expo/ui/jetpack-compose';

export default function BasicRadioButton() {
  const [selected, setSelected] = useState(false);

  return (
    <Host matchContents>
      <RadioButton selected={selected} onClick={() => setSelected(!selected)} />
    </Host>
  );
}
```

### Radio group (recommended)

The recommended pattern for a radio group follows the [Compose accessibility guidelines](https://developer.android.com/develop/ui/compose/components/radio-button):

-   Wrap the group in a `Column` with the `selectableGroup()` modifier so screen readers treat the options as a group.
-   Apply the `selectable` modifier with `role: 'radioButton'` on each `Row`, making the entire row (including the label) tappable.
-   Pass no `onClick` to the `RadioButton` itself, the row handles the interaction. This provides a larger touch target.

```tsx
import { useState } from 'react';
import { Host, Column, Row, RadioButton, Text } from '@expo/ui/jetpack-compose';
import {
  selectable,
  selectableGroup,
  fillMaxWidth,
  height,
  padding,
} from '@expo/ui/jetpack-compose/modifiers';

export default function RadioGroup() {
  const [selectedOption, setSelectedOption] = useState('Calls');
  const options = ['Calls', 'Missed', 'Friends'];

  return (
    <Host matchContents>
      <Column modifiers={[selectableGroup()]}>
        {options.map(label => (
          <Row
            key={label}
            verticalAlignment="center"
            modifiers={[
              fillMaxWidth(),
              height(56),
              selectable(label === selectedOption, () => setSelectedOption(label), 'radioButton'),
              padding(16, 0, 16, 0),
            ]}>
            <RadioButton selected={label === selectedOption} />
            <Text modifiers={[padding(16, 0, 0, 0)]}>{label}</Text>
          </Row>
        ))}
      </Column>
    </Host>
  );
}
```
