mu-calendar-picker

react-native-calendar-picker

This is a Calendar Picker Component for React Native

Scrollable CalendarPicker — New in 7.x

The scrollable prop was introduced in 7.0.0 and features a bi-directional infinite scroller. It recycles months using RecyclerListView, shifting them as the ends are reached. If the Chrome debugger is used during development, month shifting may be erratic due to a RN setTimeout bug. To prevent month shifts at the ends of the scroller, set restrictMonthNavigation, minDate, and maxDate range to 5 years or less.

To use the calendar you just need to:

npm install --save mu-calendar-picker

Prerequisites

CalendarPicker requires Moment JS >=2.0. Date props may be anything parseable by Moment: Javascript Date, Moment date, or ISO8601 datetime string.

npm install --save moment

Example

import React, { Component } from 'react';
import {
  StyleSheet,
  Text,
  View
} from 'react-native';
import CalendarPicker from 'mu-calendar-picker';

export default class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      selectedStartDate: null,
    };
    this.onDateChange = this.onDateChange.bind(this);
  }

  onDateChange(date) {
    this.setState({
      selectedStartDate: date,
    });
  }
  render() {
    const { selectedStartDate } = this.state;
    const startDate = selectedStartDate ? selectedStartDate.toString() : '';
    return (
      <View style={styles.container}>
        <CalendarPicker
          onDateChange={this.onDateChange}
        />

        <View>
          <Text>SELECTED DATE:{ startDate }</Text>
        </View>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: '#FFFFFF',
    marginTop: 100,
  },
});

Some styles will overwrite some won't. For instance:

• If you provide textStyle with fontFamily and color, out of ranges dates will not apply your color, just fontFamily.

Order of precedence:

• defaultColor => textStyle => selectedDayColor
• defaultTodayBackgroundColor => todayBackgroundColor
• defaultBackgroundColor => selectedDayColor
• defaultTextStyles => textStyle => selectedDayTextColor

Custom styling individual dates

let today = moment();
let day = today.clone().startOf('month');
let customDatesStyles = [];
while(day.add(1, 'day').isSame(today, 'month')) {
  customDatesStyles.push({
    date: day.clone(),
    // Random colors
    style: {backgroundColor: '#'+('#00000'+(Math.random()*(1<<24)|0).toString(16)).slice(-6)},
    textStyle: {color: 'black'}, // sets the font color
    containerStyle: [], // extra styling for day container
    allowDisabled: true, // allow custom style to apply to disabled dates
  });
}

render() {
  return (
    <CalendarPicker
      todayTextStyle={{fontWeight: 'bold'}}
      todayBackgroundColor={'transparent'}
      customDatesStyles={customDatesStyles}
      minDate={today}
    />
  );
}

Styling each day of the week and the day name header.

const customDayHeaderStylesCallback = {dayOfWeek, month, year} => {
  switch(dayOfWeek) { // can also evaluate month, year
    case 4: // Thursday
      return {
        style: {
          borderRadius: 12,
          backgroundColor: 'cyan',
        },
        textStyle: {
          color: 'blue',
          fontSize: 22,
          fontWeight: 'bold',
        }
      };
  }
}

const customDatesStylesCallback = date => {
  switch(date.isoWeekday()) {
    case 1: // Monday
      return {
        style:{
          backgroundColor: '#909',
        },
        textStyle: {
          color: '#0f0',
          fontWeight: 'bold',
        }
      };
    case 7: // Sunday
      return {
        textStyle: {
          color: 'red',
        }
      };
  }
}

<CalendarPicker
      customDayHeaderStyles={customDayHeaderStylesCallback}
      customDatesStyles={customDatesStylesCallback}
    />
