Color Picker Preference for AndroidX Preference Library

Color Picker PreferenceX

This is color picker for AndroidX Preference Library rewritten by using DialogPreference and PreferenceDialogFragmentCompat.

The original HoloColorPicker was written by Marie Schweiz.
I was using fork of Simon Kaiser, and fixed a lot of bugs, also added new futures such as: HEX implementation of color and DayNight theming support.

Including in project

Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
    }
   }

Add the dependency:

dependencies {
  implementation 'com.github.7Koston:HSVColorPicker:1.1.5'
}

How to use

Add the ColorPreference to your preference xml.

<?xml version="1.0" encoding="utf-8"?>
<androidx.preference.PreferenceScreen
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

  <com.github.koston.preference.ColorPreference
    style="@style/AppTheme.PreferenceDialog"
    android:defaultValue="@color/colorAccent"
    android:key="color_first"
    android:summary="Some summary"
    android:title="Color 1"
    app:hueWheelRadius="@dimen/defaultWheelRadius"
    app:hueWheelThickness="@dimen/defaultWheelThickness"
    app:centerCircleRadius="@dimen/defaultCenterRadius"
    app:centerCircleHaloRadius="@dimen/defaultCenterHaloRadius"
    app:huePointerRadius="@dimen/defaultPointerRadius"
    app:huePointerHaloRadius="@dimen/defaultPointerHaloRadius"
    app:barThickness="@dimen/defaultBarThickness"
    app:barLength="@dimen/defaultBarLength"
    app:barPointerRadius="@dimen/defaultBarPointerRadius"
    app:barPointerHaloRadius="@dimen/defaultBarPointerHaloRadius"
    app:pointersHaloColor="@color/defaultPointerHaloColor"
    app:indicatorColorPreview="true"/>
  ...

</androidx.preference.PreferenceScreen>

You have to extend ColorPreferenceFragmentCompat to your fragment, or just override onDisplayPreferenceDialog method like in ColorPreferenceFragmentCompat.

public class MyPreferenceFragment extends ColorPreferenceFragmentCompat {

    @Override public void onCreatePreferences(Bundle bundle, String s) {
        addPreferencesFromResource(R.xml.my_pref);
    }
}
