How to add continuous output?

[cloydcSU]

Is there a way to modify the color picker so that it continuously outputs a color value as it is changed? Similar to the function onProgressChanged that a seekBar uses.

Of course you can. Just create an interface with one method that returns a ColorPicker object. Implement that same interface in your ColorActivity. Than create a method in the ColorPicker class which will let you set the listener.

This is how I did it with the MultiColorPicker:

MultiColorActivity
onCreate

 multiColorPicker = (MultiColorPicker) findViewById(R.id.multiColorPicker);
        multiColorPicker.setListener(this);

Somewhere

 @Override
    public void colorChanged(MultiColorPicker multiColorPicker) {
        for(LightPointModel lightPointModel : groupLights){
            lightPointModel.setLightColor(multiColorPicker.getColor());
        }

        createLightPointViews();
    }

MultiColorPicker.java

 public void setListener(MultiColorPickerListener listener){
        this.listener = listener;
    }

MultiColor

public interface MultiColorPickerListener {
    void colorChanged(MultiColorPicker multiColorPicker);
}

Would be great if an onChange listener could be implemented directly. There doesn't appear to be a direct way to get this to work on Xamarin Android by just using the NuGet package.

By adding a choreographer I was able to solve this - just get the color every frame and safe it's value somewhere as a workaround.
