by

Important: Remember to set the ID for each view. 

RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
layout.setLayoutParams(layoutParams);

RelativeLayout.LayoutParams params1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params2 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params3 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams params4 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

TextView tv1 = new TextView(this);
tv1.setId(1);
tv1.setText("textView1");

TextView tv2 = new TextView(this);
params2.addRule(RelativeLayout.RIGHT_OF, tv1.getId());
tv2.setId(2);
tv2.setText("textView2");

TextView tv3 = new TextView(this);
params3.addRule(RelativeLayout.BELOW, tv1.getId());
tv3.setId(3);
tv3.setText("textView3");

TextView tv4 = new TextView(this);
params4.addRule(RelativeLayout.RIGHT_OF, tv3.getId());
params4.addRule(RelativeLayout.ALIGN_BOTTOM, tv3.getId());
tv4.setId(4);
tv4.setText("textView4");

layout.addView(tv1, params1);
layout.addView(tv2, params2);
layout.addView(tv3, params3);
layout.addView(tv4, params4);
