Generally used classes by Daniel Nilsson. ColorPickerPreference class by Sergey Margaritov. Packed by Sergey Margaritov. Packed again and made Gradle compatible by Vincent Fischer.

• Color Area
• Hue Slider
• Alpha Slider (disabled by default)
• Old & New Color
• Color Preview in Preferences List

Tested with APIv7, but maybe will work with early versions

You can now install this through Gradle with a simple:

implementation 'net.margaritov.preference.colorpicker.ColorPickerPreference:ColorPickerPreference:1.0.0' 

1. Paste or clone this library into the /libs folder, in the root directory of your project. Create a new folder: /libs if not already present. (This step is not required - only for keeping cleaner project structure)
2. Edit settings.gradle by adding the library. You have also define a project directory for the library. Your settings.gradle should look like below:

include ':app', ':ColorPickerPreference' project(':ColorPickerPreference').projectDir = new File('app/libs/ColorPickerPreference') 

3. In app/build.gradle add the ColorPickerPreference library as a dependency:

dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:21.0.3' implementation project(":ColorPickerPreference") } 

4. Sync project, clean and build. You can use the ColorPickerPreference library as part of your project now.

1. Before you can add a ColorPickerPreference to your application, you must first add a library reference:
2. Clone or download a copy of the library
3. Import the library into Eclipse: File menu -> Import -> Existing Project into Workspace
4. Open your application's project properties and add a library reference to ColorPickerPreference

You can see some tests inside

<net.margaritov.preference.colorpicker.ColorPickerPreference android:key="color1" android:title="@string/color1_title" android:summary="@string/color1_summary" android:defaultValue="@color/pumpkin_orange" <!-- integer resources are also accepted --> alphaSlider="true" <!-- enable alpha slider via XML --> /> 

To enable Alpha Slider in your code use function:

setAlphaSliderEnabled(boolean enable)
