Answer 1

you define your item in wrong place, define your View inside of view holder and like below

public static class AcademicVH extends RecyclerView.ViewHolder {
private LinearLayout containerData;

public AcademicVH(View itemView) {
    super(itemView);
    TextView txtSubject = (TextView) view.findViewById(R.id.txtSubjectValue);
    TextView txtGroup = (TextView) view.findViewById(R.id.txtGroupValue);
    TextView txtStatus = (TextView) view.findViewById(R.id.txtStatusValue);
    TextView txtFinalNote = (TextView) view.findViewById(R.id.txtFinalNoteValue);
    TextView txtYear = (TextView) view.findViewById(R.id.txtYearValue);
    containerData = (LinearLayout) itemView.findViewById(R.id.containerData);
    }
}

another trick, when you use condition (if) in your onBindViewHolder, you should complete it with (else).
