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 latest Android Open Source Project 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 (in styles.xml in the values folder):

<style name="NumberPickerStyle">
    <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(R.style.NumberPickerStyle)
            .showTitle(true)
            .showDaySpinner(true)
            .defaultDate(2017, 0, 1)
            .maxDate(2020, 0, 1)
            .minDate(2000, 0, 1)
            .build()
            .show();

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

Note that full support is only for API >= 18. API < 18 you'll get the DatePicker but there is no easy way to style it correctly.

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:1.0.6'
}

Philosophy

The aim of this project is to produce a lightweight and robust DatePicker with an API similar to that of the standard Android DatePicker. Hence the library has no external dependencies and no fancy features. Espresso automated UI testing is performed on the sample project using Firebase test lab.
