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

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 -

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 -

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',
},

How would you handle an onSubmit ? I've been trying for hours...

[Saad]

Hi Lucia! May I know what are you trying to do in onSubmit function?

[Lucia Buggiano]

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

[Saad]

Hi Lucia, I have updated my code snack example with an onSubmit call. Please check if it helps.

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

[SirCQQ]

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

[Emmanuel]

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

[the dude with the beer]

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

How to have a default Value selected.? For example, I want to have the first value as selected by default?

[palanpuricoder]

how to uncheck radio button?

[Saad]

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.
