Answer 1

There is two ways to change layouts in code:

A. Change visibility. Include tow different layouts in your xml:

and in code use this:

findViewById(R.id.id1).setVisibility(View.GONE);
findViewById(R.id.id2).setVisibility(View.VISIBLE);

B. Manually add children. Use the same xml as you use now and add in code you can add or delete children:

yourRelativeLayout.removeAllViews();
yourRelativeLayout.addView(viewToInclude);

You don't need to write xmlns:android param in RelativeLayout. Just for the most top tag in layout file.
