                           RelativeLayout.LayoutParams.FILL_PARENT);

              relParent.setLayoutParams(rlparent);

              RelativeLayout relTop = new RelativeLayout(HomeScreen.this);

              RelativeLayout.LayoutParams rlpTop = new RelativeLayout.LayoutParams(

                           RelativeLayout.LayoutParams.WRAP_CONTENT);

              rlpTop.addRule(RelativeLayout.ALIGN_PARENT_TOP);

              RelativeLayout.LayoutParams rlpBottom = new RelativeLayout.LayoutParams(

                           RelativeLayout.LayoutParams.FILL_PARENT,

                           RelativeLayout.LayoutParams.WRAP_CONTENT);

              rlpBottom.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);

              relTop.setLayoutParams(rlpTop);

              relBottom.setLayoutParams(rlpBottom);

              TextView txtTitle = new TextView(HomeScreen.this);

              RelativeLayout.LayoutParams relParam = new RelativeLayout.LayoutParams(

                           RelativeLayout.LayoutParams.WRAP_CONTENT,

                           RelativeLayout.LayoutParams.WRAP_CONTENT);

              relParam.addRule(RelativeLayout.CENTER_IN_PARENT);

              txtTitle.setText("HomeScreen");

              txtTitle.setLayoutParams(relParam);

              txtTitle.setTextColor(Color.BLUE);

              txtTitle.setTextSize(18);

              relTop.addView(txtTitle);

              relParent.addView(relTop);

              relParent.addView(relBottom);

              setContentView(relParent);

It does not require any layout.xml file becuase all gui is using code.
In Relative Layout , we use RelativeLayout.LayoutParams same way
In Linear Layout , we use LinearLayout.LayoutParams.
