You're passing in null as the parent ViewGroup parameter to inflate(). This will cause all layout_* attributes to be ignored, as the inflater has no idea which attributes are valid for the container in which it will be placed (i.e. it has no idea which LayoutParams type to set on the View).

View child = getLayoutInflater().inflate(R.layout.activity_main_card, null);

should be

View child = getLayoutInflater().inflate(R.layout.activity_main_card, item, false);
