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.
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'
}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);
}
}Customization:
