usernameDetails.addRule takes in two integers. One integer is the rule itself (RelativeLayout.ABOVE) the other integer is the view what it has to be above. But the redButton is a Button object. That why you set a id for the button.
And when you want to add a new button to an existing Activity that is using xml you dont have a Button object in Java. The addRule function uses an integer as an input for the view so you can use an id that you specified in a xml file.
I hope I answered your question
