Getting Started

import {Radio, RadioGroup,RadioButton} from "radio-react-native";
<RadioGroup 
    defaultChoice={1} 
    onChoose={(value,index)=>this.onChooseGender(value,index)}
    >
  <RadioButton value={"M"}>
      <Text>Male</Text><Radio/> 
  </RadioButton>
  <RadioButton value={"F"}>
     <Radio/><Text> Female</Text>
  </RadioButton>
</RadioGroup>

Examples

The Demo section shows Three different examples of the RadioGroup. In this section, I will show you how to use the radio-react-native library.

Gender example

<RadioGroup 
    defaultChoice={1} 
    style={styles.flexRow} 
    onChoose={(value,index)=>this.onChooseGender(value,index)}>  
    <RadioButton 
	    style={[styles.flexRow,styles.center,styles.halfWidth]}
	    value={"M"}>
      <Text style={styles.text}>Male  </Text>
      <Radio/> 
    </RadioButton>
 <RadioButton 
     style={[styles.flexRow,styles.center,styles.halfWidth]}
      value={"F"}>  
      <Radio/>
      <Text style={styles.text}\> Female</Text>
  </RadioButton>
</RadioGroup>

In this example, we have a radio form that contains two choices (Male, female). Two RadioButtons wrapped inside the Radio Group. Once you click on a radio the event OnChoose is emitted and you can get the value and the index of the choosen radioButton.

Age example

const ages = [  
    {id:1,age:'0 - 2',label:'baby'},
    {id:2,age:'3 - 8',label:'kid'},
    {id:'3',age:'9 - 16',label:'teenager'},
    {id:4,age:'17 - 24',label:'adult'}
];

<RadioGroup 
    defaultChoice={3} 
    onChoose={(value,index)=>this.onChooseAge(value,index)}>
    {ages.map((age)=> 
	    <RadioButton 
		    key={age.id} 
		    style={[styles.flexRow,styles.start]} 
		    value={age}>
		    <Radio/>
		    <Text style={styles.text}>{age.label} ({age.age} years old)</Text>
		</RadioButton>
	)}  
	</RadioGroup>

You can also iterate on a list and render a radio Form to choose between many options.

Custom Radio example

class ThumpsUp extends Component<Props>{  

    render(){  
        const {checked} = this.props;  
        if(checked){  
            return <Icon 
		            name={"ios-thumbs-up"} 
		            style={{color:'blue'}}/>  
            }
            else{  
            return <Icon 
		            name={"ios-thumbs-up-outline"} />  
            }  
	    }  
}

class ThumpsDown extends Component<Props>{  

    render(){  
        const {checked} = this.props;  
        if(checked){  
            return <Icon 
		            name={"ios-thumbs-down"} 
		            style={{color:'red'}}/>  
            }
            else{  
            return <Icon 
		            name={"ios-thumbs-down-outline"} />  
            }  
	    }  
}

ThumpsUp and ThumpsDown are two component defined to be used as a clickable radio in our Radio group. We need to use the checked props to return the representation of our Radio instead of the default one.

<RadioGroup 
    defaultChoice={0} 
    onChoose={(value,index)=>this.onChooseLike(value,index)}>
    <RadioButton 
	    style={[styles.flexRow,styles.start]}
	    value={true}>
	    
	    <Radio CustomComponent={ThumpsUp}/>
	    <Text style={styles.text}\> Yes</Text>
	    
    </RadioButton>
    
    <RadioButton 
	    style={[styles.flexRow,styles.start]} 
	    value={false}>
	    
	    <Radio CustomComponent={ThumpsDown}/>
	    <Text style={styles.text}\> No</Text>
	    
    </RadioButton>
</RadioGroup>

In this example, we customize the radio to render ThumpsUp adn ThumpsDown instead of the default Radio.
