Helo Dear Reader!

I'm trying to implement my custom interface for a drawing application
which contains an editor ViewGroup. The editor group moreover contains
a SurfaceView for holding the image and custom Views for toolbars. Now
I wanna make the toolbars ViewGroups as well, so I could make the
toolbar buttons as additional Views, each having their own event
handlers and drawing functions. I don't want to implement new GUI
components, but to build on Android API and only extend the drawing
and event handling functions of the View. This is necessary as I want
to display the toolbar ontop of the image so I need my customized
layout as well.

My problem is that there is no such function
ViewGroup.addView(ViewGroup view), however the documentation states on
the page about the View:

"The ViewGroup subclass is the base class for layouts, which are
invisible containers that hold other Views (or other ViewGroups) and
define their layout properties."

Could someone please explain how to nest a ViewGroup in another
ViewGroup?
