Android Landscape orientation Problem

Question

I have designed two different layouts for landscape and portrait as by this example

i tried applying android:configChanges="keyboardHidden|orientation" for the activity in the manifest.

here is the question... when i changed the orientation, the activity does not reset instead it does not apply the UI change for the orientation change.

Any one suggest me the way to achieve both.
