Assuming the layout in witch you want to add it is a LinearLayout, you can add a RadioButton like this:

LinearLayout myLayout = findViewById(R.id.main);
RadioButton myButton = new RadioButton(this);
myButton.setLayoutParams(new LinearLayout.LayoutParams(
                                 LinearLayout.LayoutParams.FILL_PARENT,
                                 LinearLayout.LayoutParams.FILL_PARENT));
myLayout.addView(myButton);
