}
}
And add the dependency
	dependencies {

}

Usage

ChromaDialog

To display a color picker DialogFragment from your Activity:
new ChromaDialog.Builder()
.initialColor(Color.GREEN)
.colorMode(ColorMode.ARGB) // RGB, ARGB, HVS, CMYK, CMYK255, HSL
.indicatorMode(IndicatorMode.HEX) //HEX or DECIMAL; Note that (HSV || HSL || CMYK) && IndicatorMode.HEX is a bad idea
.create()
.show(getSupportFragmentManager(), "ChromaDialog");
To display a color picker DialogFragment from your Fragment:
new ChromaDialog.Builder()
.initialColor(Color.GREEN)
.colorMode(ColorMode.ARGB) // RGB, ARGB, HVS, CMYK, CMYK255, HSL
.indicatorMode(IndicatorMode.HEX) //HEX or DECIMAL; Note that (HSV || HSL || CMYK) && IndicatorMode.HEX is a bad idea
.create()
.show(getChildFragmentManager(), "ChromaDialog");

Listeners

Your parent Activity or Fragment must implement the listener interfaces.

OnColorSelectedListener

OnColorSelectedListener contains two methods : void onPositiveButtonClick(@ColorInt int color)called when positiveButton is clicked and void onNegativeButtonClick(@ColorInt int color) called when negativeButton is clicked.

OnColorChangedListener

OnColorChangedListener contains method void onColorChanged(@ColorInt int color) called when color is changed in view. See MainActivity.java for complete sample of ChromaDialog

Style

For custom dialog, simply redefined following nodes :
<style name="Chroma.AlertDialog" parent="Theme.AppCompat.Light.Dialog.Alert">
<!-- Used for the buttons -->
<item name="colorAccent">#fff1c8</item>
<!-- Used for the title and text -->
<item name="android:textColorPrimary">#c7c7c7</item>
<!-- Used for the background -->
<item name="android:background">#353535</item>
</style>
<style name="Chroma.AlertDialog.Label" parent="TextAppearance.AppCompat.Body1">
<item name="android:textColor">#a7a7a7</item>
</style>
<style name="Chroma.AlertDialog.Value" parent="TextAppearance.AppCompat.Body2">
<item name="android:textColor">#939393</item>
</style>

ChromaPreferenceCompat

You must add a preferenceTheme node in your activity :
<style name="AppTheme.Settings" parent="AppTheme">
<item name="preferenceTheme">@style/PreferenceThemeOverlay.v14.Material</item>
</style>
or (for API < 14)
<style name="AppTheme.Settings" parent="AppTheme">
<item name="preferenceTheme">@style/PreferenceThemeOverlay</item>
</style>
A. Add Preference to your *.xml preference layout:
    <com.kunzisoft.androidclearchroma.ChromaPreferenceCompat
android:key="hsv" // any key you want
android:title="HSV sample" // summary will be automatically fetched from the current color
android:summary="text and [color] string" // add [color] for show current color as string in summary
app:chromaShapePreview="ROUNDED_SQUARE" // CIRCLE, SQUARE, ROUNDED_SQUARE
app:chromaColorMode="HSV" // RGB, ARGB, HSV, HSL, CMYK, CMYK255
app:chromaIndicatorMode="HEX" // HEX or DECIMAL
app:chromaInitialColor="@color/colorAccent"/> // default color
B. Or you can add preferences dynamically from the code:
    ChromaPreferenceCompat pref = new ChromaPreferenceCompat(getContext());
pref.setTitle("RGB(added from java)");
pref.setSummary("Summary ...");
pref.setColorMode(ColorMode.RGB);
pref.setIndicatorMode(IndicatorMode.HEX);
pref.setKey("any_key_you_need");
getPreferenceScreen().addPreference(pref);
You can use ChromaPreferenceFragmentCompat for an easier managing of fragment in Preferences.
public class ColorPreferenceFragmentCompat extends ChromaPreferenceFragmentCompat {
@Override
public void onCreatePreferences(Bundle bundle, String s) {
addPreferencesFromResource(R.xml.prefs_v7); // load your ChromaPreferenceCompat prefs from xml
}
}

Fragment

Simply call it in XML layout with :
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment android:name="com.kunzisoft.androidclearchroma.fragment.ChromaColorFragment"
android:id="@+id/activity_color_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:layout="@layout/chroma_color_fragment" />
</FrameLayout>
Unfortunately, you can't customize a fragment in XML. You must initialize the fragment programmatically and use the FragmentManager to add it to your layouts. Example :
    ChromaColorFragment chromaColorFragment = ChromaColorFragment.newInstance(Color.BLUE, ColorMode.ARGB, IndicatorMode.HEX);
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.container_color_fragment, chromaColorFragment, TAG_COLOR_FRAGMENT)
.commit();
See FragmentColorActivity.java for complete sample.

Bonus

Method for formatted output of a given color:
ChromaUtil.getFormattedColorString(int color, boolean showAlpha);
