do one thing make a folder named Layout-land in res folder , in which put your xml file. now you can design your xml in horizontal mode . do whatever changes you want in that file and check :
otw put a scroll bar in whole layout and then check :) good luck
Just Copy and Past in you xml file, it wil run completely. I have tested.
