:hammer: Setup

Gradle dependency:

implementation "codes.side:andcolorpicker:0.6.2"

:art: Picker types

HSL (hue, saturation, lightness)

• Add color model description

Layout XML Snippet

Basic HSL components:

<codes.side.andcolorpicker.hsl.HSLColorPickerSeekBar
  android:id="@+id/hueSeekBar"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:hslColoringMode="pure"
  app:hslMode="hue" />

Supported hslMode values:

• hue (default)
• saturation
• lightness

Supported hslColoringMode values:

• pure (default)
• output

Alpha component:

<codes.side.andcolorpicker.alpha.HSLAlphaColorPickerSeekBar
  android:id="@+id/alphaSeekBar"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" />

Kotlin Snippet

// Configure color model programmatically
hueSeekBar.mode = Mode.MODE_HUE // Mode.MODE_SATURATION, Mode.MODE_LIGHTNESS

// Configure coloring mode programmatically
hueSeekBar.coloringMode = ColoringMode.PURE_COLOR // ColoringMode.OUTPUT_COLOR

// Group pickers with PickerGroup to automatically synchronize color across them
val group = PickerGroup<IntegerHSLColor>().also {
  it.registerPickers(
    hueSeekBar,
    saturationSeekBar,
    lightnessSeekBar,
    alphaSeekBar
  )
}

// Get current color immediately
Log.d(
  TAG,
  "Current color is ${hueSeekBar.pickedColor}"
)

// Listen individual pickers or groups for changes
group.addListener(
  object : HSLColorPickerSeekBar.DefaultOnColorPickListener() {
    override fun onColorChanged(
      picker: ColorSeekBar<IntegerHSLColor>,
      color: IntegerHSLColor,
      value: Int
    ) {
      Log.d(
        TAG,
        "$color picked"
      )
      swatchView.setSwatchColor(
        color
      )
    }
  }
)

// Set desired color programmatically
group.setColor(
  IntegerHSLColor().also {
    it.setFromColorInt(
      Color.rgb(
        28,
        84,
        187
      )
    )
  }
)

// Set color components programmatically
hueSeekBar.progress = 50

Swatches

SwatchView component:

<codes.side.andcolorpicker.view.swatch.SwatchView
  android:id="@+id/swatchView"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" />

Kotlin Snippet:

swatchView.setSwatchPatternTint(
  Color.LTGRAY
)

swatchView.setSwatchColor(
  IntegerHSLColor().also {
    it.setFromColorInt(
      ColorUtils.setAlphaComponent(
        Color.MAGENTA,
        128
      )
    )
  }
)
