Answer 1

All these answers are great, but I was using ConstraintLayout, so here is code for that:

ConstraintLayout.LayoutParams params = new ConstraintLayout.LayoutParams(ConstraintLayout.LayoutParams.WRAP_CONTENT, ConstraintLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(10, 10, 10, 10);
textview.setLayoutParams(params); // note that textview would be your instanced TextView object
