Use:

popup.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);

plus, if applicable:

popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);

However, make sure you're not using fill/match_parent in the contents of popup_layout, because that wouldn't make sense (i.e. popup set to wrap its content, and the content says make me as big as my parent). Post your popup_layout XML for a more exact answer.
