# react-native-radio-buttons



*IMPORTANT* this package is deprecated and no longer maintained in favor of the official [SegmentedControlIOS](https://facebook.github.io/react-native/docs/segmentedcontrolios.html) component.



A react component to implement _radio buttons_-like behaviors: multiple options, only one option can be selected at a given time.



Both the container and option nodes are customizable. Comes with SegmentedControls clone, only more customizable (see below, animations to come).



![example](./images/example.png)



## Install



```sh

npm i -S react-native-radio-buttons

```



## Demo app



```sh

git clone https://github.com/ArnaudRinquin/react-native-radio-buttons.git

cd react-native-radio-buttons

npm run demo

```



## Usage



Here is an extensive overview of the component usage.



```jsx

import { RadioButtons } from 'react-native-radio-buttons'



// ...



render() {

  const options = [

    "Option 1",

    "Option 2"

  ];



  function setSelectedOption(selectedOption){

    this.setState({

      selectedOption

    });

  }



  function renderOption(option, selected, onSelect, index){

    const style = selected ? { fontWeight: 'bold'} : {};



    return (

      

        {option}

      

    );

  }



  function renderContainer(optionNodes){

    return {optionNodes};

  }



  return (

    

      

      Selected option: {this.state.selectedOption || 'none'}

    );

}



```



Will render this

## Props



* `options - []` mandatory array of anything, will be passed to `renderOption`

* `onSelection - function(selectedOption, selectedIndex){}` option selection callback

* `selectedIndex - index` the  initially selected index, optional.

* `selectedOption - option` the initially selected option, optional

* `renderOption - function(option, selected, onSelect, index)` should return an option node, default generate `` nodes and adds `{fontWeight:'bold'}` to the selected option.

* `renderContainer - function(optionsNodes)` must render the container, default is RadioButtons.renderVerticalContainer (see below)

* `optionStyle` - optional styles to be applied to the `` elements of the options themselves.

* `optionContainerStyle` - optional styles to be applied to the the `` that contain the options.

* `testOptionEqual- function(selectedOption, currentOption){}` optional compares and returns bool.



### Full JavaScript SegmentedControls clone



This library comes with a clone of the native `SegmentedControls`, based on `RadioButtons`.



```jsx

import { SegmentedControls } from 'react-native-radio-buttons'



// ...



```



You override all the defaults through the props.



```jsx



```



Here is the list of the props you might override:



```jsx

const IOS_BLUE = '#007AFF';

const IOS_WHITE = '#ffffff';



const DEFAULTS = {

  direction: 'row',



  tint: IOS_BLUE,

  backTint: IOS_WHITE,



  paddingTop: 5,

  paddingBottom: 5,

  textAlign: 'center',



  selectedTint: IOS_WHITE,

  selectedBackgroundColor: IOS_WHITE,



  separatorTint: IOS_BLUE,

  separatorWidth: 1,



  containerBorderTint: IOS_BLUE,

  containerBorderWidth: 1,

  containerBorderRadius: 5,



}

```



You can also specify `containerStyle`, `optionContainerStyle`, and `optionStyle` to use any style you want:



* `containerStyle` - optional styles to be applied to the outermost `` component.

* `optionStyle` - optional styles to be applied to the `` elements of the options themselves.

* `optionContainerStyle` - optional styles to be applied to the the `` that contain the options.



You can also specify how to extract the labels from the options through the extractText prop.



```jsx

options = [

  {

    label: 'Option 1',

    value: 'opt1'

  },

  {

    label: 'Option 2',

    value: 'opt2'

  }

]



 option.label }

/>

```



If you decide to declare `options` as an array of objects, do also include a `testOptionEqual` prop for customized equality checking, otherwise changing `selectedOption` programmatically would not update the UI correctly. 



With the above `options`, you'll need `testOptionEqual` to be as follows in order for `selectedOption` to display correctly.



```jsx

   option.label }

    testOptionEqual={(selectedValue, option) => selectedValue === option.value}

  />

```



Moreover, you can even specify the whole `renderOption()` function:



```jsx

 {

    return (

      // ...render stuff

    )

  }}

}}

```



## Helpers

**RadioButtons.renderVerticalContainer;**



A super simple `renderContainer` function that generates a  with `{flexDirection: "column"}`. It is used as default `renderContainer` if you don't specify it.



Usage:



```jsx



```



**RadioButtons.renderHorizontalContainer;**



Another super simple `renderContainer` function that generates a  with `{flexDirection: "row"}`



Usage:



```jsx



```



**RadioButtons.getViewContainerRenderer(viewContainerStyle);**



An helper that generates a simple `` with the provided style.



Usage:



```jsx



```



**RadioButtons.getTextOptionRenderer(normalStyle, selectedStyle, extractText);**



An helper that generates `` options wrapped in ``.

`normalStyle` and `selectedStyle` will be applied to the  nodes, depending on state. `extractText(options)` can be specified.



Usage:



```jsx

const normalStyle = {

  color: 'white'

};



const selectedStyle = {

  color: '#f80046',

  fontWeight: 'bold'

};



const extractText = (option) => option.label;



```
