Marie Schweiz http://marie-schweiz.de/ made a beautifull new design for the Holo ColorPicker which added a lot of new functionality.
You can now set the Saturation and Value of a color. Also its possible to set the Opacity for a color.
You can also set the last selected color and see the difference with the new selected color.
Demo can be found on my Google Drive here if interested. the code of the sample can be found at a gist here
To add the ColorPicker to your layout add this to your xml
<com.larswerkman.holocolorpicker.ColorPicker android:id="@+id/picker" android:layout_width="wrap_content" android:layout_height="wrap_content"/>To add a Saturation/Value bar to your layout add this to your xml
<com.larswerkman.holocolorpicker.SVBar android:id="@+id/svbar" android:layout_width="wrap_content" android:layout_height="wrap_content"/>The same goes for the Opacity bar
<com.larswerkman.holocolorpicker.OpacityBar android:id="@+id/opacitybar" android:layout_width="wrap_content" android:layout_height="wrap_content"/>Saturation bar
<com.larswerkman.holocolorpicker.SaturationBar android:id="@+id/saturationbar" android:layout_width="wrap_content" android:layout_height="wrap_content"/>and a Value bar
<com.larswerkman.holocolorpicker.ValueBar android:id="@+id/valuebar" android:layout_width="wrap_content" android:layout_height="wrap_content"/>To connect the bars with the colorpicker and to get the selected color.
