react-native-wheel-picker-extended

Introduction

Cross platform Picker component for React-native.

This repo is a fork of react-native-wheel-picker, I just add lineColor and fontFamily support.

Since picker is originally supported by ios while Android only supports a ugly Spinner component. If you want to have the same user behaviour, you can use this.

The android component is based on https://github.com/AigeStudio/WheelPicker which runs super fast and smoothly. It also supports curved effect which make it exactly the same looking and feel as the ios picker.

How to use

Run command

For apps using RN 0.40 or higher, please run

npm i react-native-wheel-picker-extended --save

Add in settings.gradle

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

Add in app/build.gradle

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

Modify MainApplication

    import com.zyu.ReactNativeWheelPickerPackage;
    ......

    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(), new ReactNativeWheelPickerPackage()
        );
    }

Example code

import React, { Component } from 'react';
import {
	Platform,
	StyleSheet,
	Text,
	View,
} from 'react-native';


import Picker from 'react-native-wheel-picker-extended'
var PickerItem = Picker.Item;

export default class App extends Component<{}> {

	constructor(props) {
		super(props);
		this.state = {
			selectedItem : 2,
			itemList: ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 5', 'Item 6', 'Item 7', 'Item 8']
		};
	}

	onPickerSelect (index) {
		this.setState({
			selectedItem: index,
		});
	}

	onAddItem = () => {
		var name = '+ Item (N)';
		if (this.state.itemList.indexOf(name) == -1) {
			this.state.itemList.push(name);
		}
		this.setState({
			selectedItem: this.state.itemList.indexOf(name)
		});
	}

	render () {
		return (
			<View style={styles.container}>
				<Text style={styles.welcome}>
					Welcome to React Wheel Picker!
				</Text>
				<Picker style={{width: 150, height: 180}}
					selectedValue={this.state.selectedItem}
					itemStyle={{color:"white", fontSize:26}}
					onValueChange={(index) => this.onPickerSelect(index)}>
						{this.state.itemList.map((value, i) => (
							<PickerItem label={value} value={i} key={"money"+value}/>
						))}
				</Picker>
				<Text style={{margin: 20, color: '#ffffff'}}>
					Selected Item：{this.state.itemList[this.state.selectedItem]}
				</Text>

				<Text style={{margin: 20, color: '#ffffff'}}
						onPress={this.onAddItem}>
			Add another item
				</Text>
			</View>
		);
	}
}

const styles = StyleSheet.create({
	container: {
		flex: 1,
		justifyContent: 'center',
		alignItems: 'center',
		backgroundColor: '#1962dd',
	},
	welcome: {
		fontSize: 20,
		textAlign: 'center',
		margin: 10,
		color: '#ffffff',
	},
	instructions: {
		textAlign: 'center',
		color: '#333333',
		marginBottom: 5,
	},
});
