Answer 1

You can do it this way. I also added setting of the margins:

RelativeLayout targetItem = (RelativeLayout) findViewById(R.id.RelativeLayout01);
RelativeLayout.LayoutParams adaptLayout = new RelativeLayout.LayoutParams(mWidth, mHeight);
adaptLayout.setMargins(marginLeft, marginTop, marginRight, marginBottom);   
targetItem.setLayoutParams(adaptLayout);                    

For mWidth and mHeight you also may set dip values to make it adapt to the different screen sizes. Easy way to do that is to define Dimension in your strings.xml and work with them, not with absolute values.

So, if you define relative_width as 120dip, and relative_height as 100 dip then in code you have

RelativeLayout.LayoutParams adaptLayout = new RelativeLayout.LayoutParams(getResources().getDimension(R.dimen.relative_width), getResources().getDimension(R.dimen.relative_height));
