Um, write your own trivial subclass of ImageView that lets you render a
portion of the image?

Hello,
I´ve deleted the last post and I´m rewriting this one trying to make
things a little bit more clear and comprehensive.
What I´m trying to archive is to be able to draw an ImageView
partially off-screen, outside it´s parent relativelayout, without
android resizing it automatically.
The cenario:
I have a layout composed of:
- RelativeLayout
- RelativeLayout
- ImageView in quiestion
- A lot of other widgets
Since the widget´s parent is a relativelayout I´m using a
RelativeLayout.LayoutParams to be able to reposition it on screen
using absolute coodinates (in pixels). This will be combined with a
TouchListener to track drag&drop from the users.
When I use LayoutParams to draw the ImageView off-screen on the left
(it´s X position< 0) the app reacts just the way I want and part of
the image is drawn on the screen while the rest of it get hidden on
the left.
My problem starts when I try to do the same move but to the other
side, where the image should get hidden off-screen on the right:
android doesn´t allow it to cross the bondaries of the RelativeLayout
and starts resizing the image to still fit on the screen. If I
understood it right, the imageview is getting positioned on the
outside but android resizes the image drawn to fit on the portion of
the imageview that is still inside the screen area.
What I need here is to make the system react the same way on both
sides, allowing the image to be drawn off-screen, without any resizing
or other transformation.
I still think this is probably just a parameter but I´ve spent the
whole afternoon reading android docs and posts on the web and could
not make it.
I hope you guys can help me.
Thank you very much for your time,
Gabriel Simões
