Try to initialize your view on RecyclerView.ViewHolder and inflate your layout on onCreateViewHolder() and don't inflate again the layout in onBindViewHolder().

public class AcademicAdapter extends RecyclerView.Adapter {
    private LayoutInflater inflater;
    private List data;

public AcademicAdapter(List data) {
    this.data = data;
}

@Override
public AcademicVH onCreateViewHolder(ViewGroup parent, int viewType) {

    View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_academic_level, parent, false);
    AcademicVH mViewHold = new ViewHolder(mView);
    return mViewHold;
}

@Override
public void onBindViewHolder(AcademicVH holder, int position) {
     final AcademicStatus mItems=this.data.get(position);


    holder.txtSubject.setText(mItems.getSubject());
    holder.txtGroup.setText(mItems.getGroup());
    holder.txtStatus.setText(mItems.getStatus());
    holder.txtFinalNote.setText(mItems.getFinalNote());
    holder.txtYear.setText(mItems.getAcademicYear());

}

@Override
public int getItemCount() {
    return data.size();
}

public static class AcademicVH extends RecyclerView.ViewHolder {
    public LinearLayout containerData;
    public TextView txtSubject,txtGroup,txtStatus,txtFinalNote,txtYear;

    public AcademicVH(View itemView) {
        super(itemView);

        containerData = (LinearLayout) itemView.findViewById(R.id.containerData);
        txtSubject = (TextView) itemView.findViewById(R.id.txtSubjectValue);
        txtGroup = (TextView) itemView.findViewById(R.id.txtGroupValue);
        txtStatus = (TextView) itemView.findViewById(R.id.txtStatusValue);
        txtFinalNote = (TextView) itemView.findViewById(R.id.txtFinalNoteValue);
        txtYear = (TextView) itemView.findViewById(R.id.txtYearValue);
    }
}
}
