you will need to Create layout at rumTime , because you can't edit anything into your xml . all you have is its resource reference R.layout.layout_name ;

So after creating layout RumTime , let your user redesign it....and save new coordinates/settings into persistent storage like shared preference or database/file . when later you when need updated layout pick these settings up and use them .
