Spinner DatePicker

Summary

The old "spinner" style DatePicker for newer devices.

Motivation

The default Material Design DatePicker has poor usability for choosing a date of birth. It seems it is hard for users to find the "year" button and they will often simply swipe left or right through the months in order to find their date of birth.

The previous Holo DatePicker with sliding NumberPickers is much more suitable for this use case however it is no longer available for Marshmallow devices and up.

This library is heavily based on the open source Contacts App DatePicker (source code here) with the addition of being able to style the NumberPickers (the dials/spinners in the DatePicker).

Adding styles

The DatePicker is the simple aggregation of three NumberPickers. You can style the DatePicker easily with a NumberPicker style:

<style name="NumbePickerStyle">
  <item name="android:textSize">22dp</item>
  <item name="android:textColorPrimary">@color/colorAccent</item>
  <item name="android:colorControlNormal" tools:targetApi="lollipop">@color/colorAccent</item> </style>

where colorControlNormal is the color of the horizontal bars (dividers) in the NumberPicker. See this StackOverflow question

And then:


 new SpinnerDatePickerDialogBuilder()

 .context(MainActivity.this)

 .callback(MainActivity.this)

 .spinnerTheme(spinnerTheme)

 .year(year)

 .monthOfYear(monthOfYear)

 .dayOfMonth(dayOfMonth)

 .build()

 .show();

The example project should make it clear - get it by cloning the repo.

Usage in a project

Add the following to your project level build.gradle:

allprojects {

  repositories {

maven {
 url "https://jitpack.io" 
}

  
}
 
}

Add this to your app level build.gradle:

dependencies {

  compile 'com.github.drawers:SpinnerDatePicker:0.0.8' 
}

Philosophy

The aim of this project is to produce a lightweight and robust DatePicker. Hence the library has no external dependencies and no fancy features. Espresso automated UI pesting is performed on the sample project using Firebase test lab. When more funds are available, more devices will be tested.

adk-toolkit exposes an AdkManager to manage UsbManager and UsbAccessory. In this way you don't need to fully understand some background concept about how ADK works but, as soon as possible, you should read ADK official documentation.

gradle-robojava-plugin

Robojava is a Gradle plugin that allows simple integration of Robolectric into Android Studio. This plugin works by creating a stub java project. This allows extending it with powerful plugins that are compatible with gradle java projects, but not with gradle android projects, like Gradle Cobertura Plugin for example.
