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',
},

I used the Radio Buttons as options to flag content and made the text options “Innapropriate”, “Misteading”, “Irrelevant” etc. I want to change the “selected” state to the clicked option.value and save it

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}

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

{item.text}


style={Styles.radioCircleStyles}
onPress={this.props.onPress}

{this.props.value === item.key && ()}

Hi, good question. You can do it easily by checking if the value is already selected, if it is already selected then make the value state null. I have updated the snack, You can also check the image.
