summary of options

color wheel you prefer (wheel only)
color wheel and a before and after circle in the middle
color wheel and a slider for switching between different color spaces
color wheel, a slider for the colorspace and the opacity
slider only, toggle for 5 different shades you define
slider only and opacity

color wheel you prefer (wheel only)

LobsterPicker lobsterPicker = (LobsterPicker) findViewById(R.id.lobsterpicker);

//To retrieve the selected color use
lobsterPicker.getColor();

//You'r also able to add a listener
lobsterPicker.addOnColorListener(new OnColorListener() {
    @Override
    public void onColorChanged(@ColorInt int color) {
        
    }

    @Override
    public void onColorSelected(@ColorInt int color) {

    }
});

color wheel and a before and after circle in the middle

By default this is disabled your able to enable it in xml

app:color_history_enabled="true"

Or in Java

LobsterPicker lobsterPicker = (LobsterPicker) findViewById(R.id.lobsterpicker);

//To enable to color feedback use
lobsterPicker.setColorHistoryEnabled(true);

//To set a previous picked color or reference color use
lobsterPicker.setHistory(Color.RED);

color wheel and a slider for switching between different color spaces

To connect a slider to the color wheel use

LobsterPicker lobsterPicker = (LobsterPicker) findViewById(R.id.lobsterpicker);
LobsterShadeSlider shadeSlider = (LobsterShadeSlider) findViewById(R.id.shadeslider);

//To connect them
lobsterpicker.addDecorator(shadeSlider);

All sliders implement the ColorDecorator interface, which enables them to manipulate the user selected color. Important to notice is the sequence you add decorators, because the first decorator that is added will be the first to manipulate the color.

color wheel, a slider for the colorspace and the opacity

To connect both the LobsterShadeSlider and LobsterOpacitySlider isn't any diffent then the previous mentioned method

LobsterPicker lobsterPicker = (LobsterPicker) findViewById(R.id.lobsterpicker);
LobsterShadeSlider shadeSlider = (LobsterShadeSlider) findViewById(R.id.shadeslider);
LobsterOpacitySlider opacitySlider = (LobsterOpacitySlider) findViewById(R.id.opacityslider);

//To connect them
lobsterpicker.addDecorator(shadeSlider);
lobsterpicker.addDecorator(opacitySlider);

slider only, toggle for 5 different shades you define

The LobsterShadeSlider can also be used as a standalone color selector.

//To retrieve to color is the same mehtod used for the LobsterPicker
shadeSlider.getColor();

To use your own colors this can be done by implementing the ColorAdapter interface. Or use the existing BitmapColorAdapter which takes a Drawable as color source.

lobsterPicker.setColorAdapter(new BitmapColorAdapter(this, R.drawable.default_shader_pallete));

slider only and opacity

Just like for the LobsterPicker you have to add the opacity slider as a decorator

LobsterShadeSlider shadeSlider = (LobsterShadeSlider) findViewById(R.id.shadeslider);
LobsterOpacitySlider opacitySlider = (LobsterOpacitySlider) findViewById(R.id.opacityslider);

//To connect them
shadeSlider.addDecorator(opacitySlider);
