React Native Radio Button Create your own radio button component in react native easily

saadbashar profile image Saad Updated on ・1 min read

You can easily create your own radio button components in react native very easily. First you need to create an array of options for your radio buttons and pass it to your radio button component like so:

const options = [
    {
        key: 'pay',
        text: 'Most High Pay',
    },
    {
        key: 'performance',
        text: 'Most Perfomance',
    },
    {
        key: 'aToZ',
        text: 'A - Z',
    },
    {
        key: 'zToA',
        text: 'Z - A',
    },
];

{...}
<RadioButtons options={options} />

after this in your radio button component you can map all these options in your render method and create radio button views

{options.map(item => {
    return (
        <View key={item.key} style={styles.buttonContainer}>
            <Text>{item.text}</Text>
            <TouchableOpacity style={styles.circle} />
        </View>
    });
}

this will create default radio buttons which looks like this -

default

Right now it is time to set the state when clicked on the radio button. First we declare our state

state = { value: null }

then inside out tag we define our checked button when clicked on any particular button.

<TouchableOpacity
    style={styles.circle}
    onPress={() => this.setState({ value: key })} // we set our value state to key
>
    { value === item.key && (<View style={styles.checkedCircle} />) } // when value is equal to key
</TouchableOpacity>

So right now when clicked it looks like this -

checked

finally the styles -

buttonContainer: {
    flexDirection: 'row',
    justifyContent: 'space-between',
    alignItems: 'center',
    marginBottom: 30,
},
circle: {
    height: 20,
    width: 20,
    borderRadius: 10,
    borderWidth: 1,
    borderColor: '#ACACAC',
    alignItems: 'center',
    justifyContent: 'center',
},
checkedCircle: {
    width: 14,
    height: 14,
    borderRadius: 7,
    backgroundColor: '#794F9B',
},

Great post.
I didn't copy paste this into my project although used this as inspiration to build my own radio button component - thank dude!

 

i have used the same but did not get item key when click on the radio button.

 

can you please share your code?

 

RadioButton.js

class RadioButton extends Component {
constructor(props) {
super(props)
this.state = {
value: null,
Arr: []
}
}
_renderRadioButton() {
return this.props.Arr.map((item, i) => {
return (


{item.text}


style={Styles.radioCircleStyles}
onPress={this.props.onPress}
>
{this.props.value === item.key && ()}



)
})
}

render() {
    return (
        <View style={Styles.radioButtonMainContainerStyles} >
            {this._renderRadioButton()}
        </View>


    )
}

}

APP.jS

this._handleRadioButton(item)} value ={this.state.value}/>

Please find the screenshot for the error
Or Send me your email-id i will share you my code.

 

hello , how you can pass the state in a props of your component ?

 

When you use a component that you create you can pass props like arguments, there you can pass the state too like

In you component you can access it like

{this.props.nameOfThePropInTheComponent}

Hope it helps you :D

 

in fact, I found the answer rather quickly but on the spot I do not remember more ....
Thank you for your answer !!

 

How can we customize a radio button to square blocks?
