    }
}

 <com.ak.android.widget.colorpickerseekbar.ColorPickerSeekBar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/colorpicker"/>

To receive color change events when the user drags along the seekbar register a ColorPickerSeekBar.OnColorSeekBarChangeListener

colorPickerSeekBar.setOnColorSeekbarChangeListener(new ColorPickerSeekBar.OnColorSeekBarChangeListener() {
            @Override
            public void onColorChanged(SeekBar seekBar, int color, boolean fromUser) {
                view.setBackgroundColor(color);
            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }
