react-native-analog-clock

React native analog clock as a nice alternative to traditional timepicker.

This component is a bridge over native BEMAnalogClock

• Adjust the time on the clock via touch (or disable it)
• customizable
• native behind

NOTE: this native bridge is an Objective-C bridge. A Swift bridge version — not published and just for technical comparison experience — is available here

See this full example source here

Install

IMPORTANT: this component is build with React Native 0.30+ (not tested with lower versions of RN).

install in your project

npm i --save react-native-analog-clock

Use

import AnalogClock component

A minimalist (a bit ugly) example:

import AnalogClock from 'react-native-analog-clock';
// in your render()
render() {
  return (
    <AnalogClock
      style={{
        width: 150,
        height: 150
      }}
      onTimeChange={
        ({hours, minutes, seconds}) => console.log(`time is now : ${hours}:${minutes}:${seconds}`)
      }
    />    
  );
}

A super complete example:

import AnalogClock from 'react-native-analog-clock';
// in your render()
render() {
  //NOTE: state should be initialized in your constructor (I just abbreviate)
  const { demoConfigParameters } = this.state;
  const { hours, minutes, seconds } = this.state;
  const { currentHours, currentMinutes, currentSeconds } = this.state;
  const { enableShadows, realTime, militaryTime, currentTime, enableDigit, setTimeViaTouch, enableGraduations, enableHub } = this.state;
  const { borderColor, borderWidth, borderAlpha } = this.state;
  const { digitOffset, digitColor } = this.state;
  const { faceBackgroundColor, faceBackgroundAlpha } = this.state;
  const { hourHandColor, hourHandAlpha, hourHandWidth, hourHandLength, hourHandOffsideLength } = this.state;
  const { minuteHandColor, minuteHandAlpha, minuteHandWidth, minuteHandLength, minuteHandOffsideLength } = this.state;
  const { secondHandColor, secondHandAlpha, secondHandWidth, secondHandLength, secondHandOffsideLength } = this.state;
  const { hubColor, hubAlpha, hubRadius } = this.state;
  const { accentGraduationModulo, bridgeHighGraduationColor, bridgeSmallGraduationColor, highGraduationWidth, smallGraduationWidth, highGraduationLength, smallGraduationLength } = this.state;
  return (
    <AnalogClock
      ref={(ref)=>{this.analogClock = ref;}}
      style={{
        height: 140,
        width: 140,

Properties

General Clock Properties:

| Property name | type | Description | | --- | --- | --- | | hours | number | manually define hours | | minutes | number | manually define minutes | | seconds | number | manually define seconds | | enableShadows | bool | If set to true, the hands will cast a shadow. Default value is true. | | realTime | bool | If set to true, the clock will be updated in real time (the second hand will move every second, the minute hand every minute...). Default value is false | | militaryTime | bool | If set to true, the clock time will support military time. Default value is false. | | currentTime | bool | If set to true, the clock will be set to the current time on the phone. Prioritized over setting the time manually. Default value is false. | | enableDigit | bool | If set to true, the digits (1-12) will be displayed on the face of the clock. Default value is false. | | setTimeViaTouch | bool | If set to true, the clock time can be updated via touch inputs. Default value is false. | | enableGraduations | bool | If set to true, the graduation on the clock will be visible. See the methods bellow to customize the graduations. Default value is true. | | enableHub | bool | If set to true, a circular hub will be drawn. Default value is false |

Current time callback:

| Name | Parameter | Parameter details | | --- | --- | --- | | onTimeChange | object | {hours, minutes, seconds} |
