Getting started

import RadioForm, {RadioButton, RadioButtonInput, RadioButtonLabel} from 'react-native-simple-radio-button';


var radio_props = [
  {label: 'param1', value: 0 },
  {label: 'param2', value: 1 }
];

var RadioButtonProject = React.createClass({
  getInitialState: function() {
    return {
      value: 0,
    }
  },
  render: function() {
    return (
      <View>
        <RadioForm
          radio_props={radio_props}
          initial={0}
          onPress={(value) => {this.setState({value:value})}}
        />
      </View>
    );
  }
});

Basic

<RadioForm
  radio_props={radio_props}
  initial={0}
  onPress={(value) => {this.setState({value:value})}}
/>

Advanced

<RadioForm
  radio_props={this.state.types}
  initial={0}
  formHorizontal={false}
  labelHorizontal={true}
  buttonColor={'#2196f3'}
  animation={true}
  onPress={(value) => {this.setState({value:value})}}
/>

  {/* To create radio buttons, loop through your array of options */}
  {
    radio_props.map((obj, i) => (

        {/*  You can set RadioButtonLabel before RadioButtonInput */}
        <RadioButtonInput
          obj={obj}
          index={i}
          isSelected={this.state.value3Index === i}
          onPress={onPress}
          borderWidth={1}
          buttonInnerColor={'#e74c3c'}
          buttonOuterColor={this.state.value3Index === i ? '#2196f3' : '#000'}
          buttonSize={40}
          buttonOuterSize={80}
          buttonStyle={{}}
          buttonWrapStyle={{marginLeft: 10}}
        />
        <RadioButtonLabel
