ColorPicker

Color picker view library provides selection of a color via human-perceivable form HSB using three selectors: hue, saturation and brightness. The code is very simple and small (on August 2020).

Concept and screenshots

Concept of color picker dialog with some hints:

• Initial and current colors are placed side-by-side, so the difference can be clearly visible
• Numbers behind each component provide the ability to "recreate" the color later
• No puzzles which color you get with HSB model

Live screenshots:

Dark theme	Light theme with transparency

Action demo:

Slider stripes and manipulator dots adapt their color on moving other sliders.

Add color picker to your project

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

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

Step 2. Add the dependency

	dependencies {
	        implementation 'com.github.applikationsprogramvara:ColorPicker:1.0.1'
	}

Usage

Color picker is ready to use out of the box with several lines added to your code.

As a dialog:

    new ColorPickerDialog(this)
            .setTitle("Color picker dialog")
            .setInitialParameters( initalColor, false)
            .setPositiveButton("OK", color -> {
                // process the new color
            })
            .setNegativeButton("Cancel", null)
            .show();

As a view in XML:

    <com.applikationsprogramvara.colorpicker.ColorPickerSlidersView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:transparency="false"
        app:initialColor="#9B3232"
        />

Things to do

• Manupulator theming and contrast on low brightness
• Alternative one-tap palette with all possible colors
• Landscape mode
• Digital input and copy/paste HTML-colors
• Preference
• Get rid of jumping color patches due to extra digit
