Color Preference

A custom preference item for easy implementation of a color picker in the preference screen. You can use the inbuilt picker or any other color picker of your choice.

Setup

Gradle

Add this to your project level build.gradle:

allprojects {
 repositories {
    jcenter()
    maven { url "https://jitpack.io" }
 }
}

Add this to your app build.gradle:

dependencies {
	compile 'com.github.kizitonwose:colorpreference:1.0.0'
}

Usage

Just like every other preference object, you add it to the XML file of your Preference screen.

<com.kizitonwose.colorpreference.ColorPreference
            android:defaultValue="@color/color_default"
            android:key="color_pref" />

<CheckBoxPreference
            ... />

<SwitchPreference
            ... />

The default implementation is the circle color view. For custom settings, add the app namespace to your XML file:

xmlns:app="http://schemas.android.com/apk/res-auto"

Now you can use the custom attributes.

<com.kizitonwose.colorpreference.ColorPreference
            android:defaultValue="@color/color_default"
            android:key="color_pref"
            android:summary="@string/pref_summary"
            android:title="@string/pref_title"
            app:colorShape="square"
            app:colorChoices="@array/color_choices"
            app:viewSize="large"
            app:numColumns="5
            app:showDialog="false" />

Attributes

attribute name	description	default value
colorShape	The shape of the color view(circle or square)	circle
colorChoices	An array of colors to show on the dialog	An internal array
viewSize	The size of the color view(normal or large)	large
numColumns	The number of columns for the colors on the dialog	5
showDialog	If false, the user can suppress the in-built dialog and then show a custom color picker. To save the color from the custom picker, just call setValue(int newColor)	true

Custom Picker sample

You can find a working example of the custom picker option in the included sample module. Actually, all you have to do is include the app:showDialog="false" in the preference item to suppress the inbuilt picker, then call the setValue(int newColor) method of the ColorPreference class and pass in the color int from the custom color picker.

The custom picker in the sample uses the Lobster Color Picker Library. You can use any color picker that is available on Android.

Credits

Original code belongs to Roman Nurik of Google, I did some additions like the view size, color shape and the ability to use a custom color picker(more to come). It's also now available as a Gradle dependency for easy usage.
