Auto linking

Note: Doesn't work with RN v0.55, not tested with v0.56

react-native link @delightfulstudio/react-native-wheel-picker-android

Manual linking

Open android/settings.gradle and add the following two lines right above include ':app':

include ':react-native-wheel-picker-android'
project(':react-native-wheel-picker-android').projectDir = new File(rootProject.projectDir, '../node_modules/@delightfulstudio/react-native-wheel-picker-android/android')

Open android/app/build.gradle and add the following line to dependencies section:

compile project(':react-native-wheel-picker-android')

Open android/app/java/com/{your package name}/MainApplication.java and add the following line right below package com.{your package name}

import com.delightfulstudio.wheelpicker.WheelPickerPackage;

In the same file find method getPackages() and add new WheelPickerPackage() at the end of the returned array, like this:

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new WheelPickerPackage() // << add this line
      );
    }

Wheel Picker

import { WheelPicker } from '@delightfulstudio/react-native-wheel-picker-android'
...

        const arr = [1,2,3];
        return (
        <WheelPicker
            onItemSelected={ event => {/* do something */} }

            style={{width:300, height: 300}}/>
        );
  }
...

Props

data

An array of options. This should be provided with an array of strings or array of numbers.

onItemSelected(event)

Callback with event in the form event = { data: 1, position: 0 }

Date Picker

import { DatePicker } from '@delightfulstudio/react-native-wheel-picker-android'
...

    render() {
        const now = new Date();
        return (
            <DatePicker
                date={ now }
                mode="datetime"
                onDateChange={ this.onDateSelected }/>
        );
    }

    onDateSelected = date => {
        // do something
    };
...

Props

* mode: 'date' doesn't support year selection, therefor it is not suitable for large range of dates, ex: birthdays.

** locale: "<locale id>" support is limited to 12/24 mode and names of months and days, it also requires explicit import 'moment/locale/<locale id>' somewhere in your script for any non-english locales to work properly.

*** style can be used to change background color and surrounding margin/padding

**** styles were tested only with size, padding and margin style properties, other properties may not work
