[android-developers] Re: Resizing and relocating images/text (similar to powerpoint), on android

Off the top of my head I'd agree with your mentor if you are working
with standard android ui elements, however if you were to draw the
whole view yourself using canvas/ogl it shouldn't be too hard to trap
the raw touch inputs and drag/resize elements at will. You'd need to
build your own scene manager to handle working out what element has
been touched, wether the user is pinching, rotating etc. More work
than just dropping some ui elements in an xml file but not impossible.
