I ran not to use two CardView in RecyclerView, who can help me?

public class RecyclerViewAdaptor extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

private static final int FIRST = 0;
private static final int SECOND = 1;

private ArrayList<ProdusSave> arrayList = new ArrayList<>();
private Context ctx;
private String name = "dsada";

public RecyclerViewAdaptor(ArrayList<ProdusSave> arrayList, Context ctx) {
this.arrayList = arrayList;
this.ctx = ctx;
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
RecyclerView.ViewHolder viewHolder = null;
if (viewType == SECOND) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_products_save, parent, false);
// RecyclerViewAdaptor.RecyclerViewHolder recyclerViewHolder = new RecyclerViewAdaptor.RecyclerViewHolder(view, ctx, arrayList);
// return recyclerViewHolder;
viewHolder = new RecyclerViewHolder(view, ctx, arrayList);
} else if (viewType == FIRST) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_products_save_title, parent, false);
// RecyclerViewAdaptor.RecyclerViewHolderTitle recyclerViewHolder = new RecyclerViewAdaptor.RecyclerViewHolderTitle(view, ctx, arrayList);
// return recyclerViewHolder;
viewHolder = new RecyclerViewHolderTitle(view, ctx, arrayList);
}
return viewHolder;
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

int nType = getItemViewType(position);

if (nType == SECOND) {
ProdusSave produsSave = arrayList.get(position);
RecyclerViewHolder recyclerViewHolder = (RecyclerViewHolder) holder;
recyclerViewHolder.size.setText(produsSave.getSize_name());
recyclerViewHolder.color.setText(produsSave.getColor_name());
recyclerViewHolder.count.setText(String.valueOf(produsSave.getCount_prod()));
} else {
ProdusSave produsSave = arrayList.get(position);
RecyclerViewHolderTitle recyclerViewHolderTitle = (RecyclerViewHolderTitle) holder;
recyclerViewHolderTitle.title.setText(produsSave.getSize_name());
recyclerViewHolderTitle.count_final.setText(String.valueOf(produsSave.getCount_final()));
}

}

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

@Override
public int getItemViewType(int position) {

int nType = SECOND;

ProdusSave produsSave = arrayList.get(position);

if (!(name.equals(produsSave.getName()))) {
nType = FIRST;
name = produsSave.getName();
}
return nType;
}

public class RecyclerViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

private TextView size, color, count;
private ImageButton up, down, delete;
private ArrayList<ProdusSave> produsSaves = new ArrayList<>();
private Context ctx;

public RecyclerViewHolder(View view, Context ctx, ArrayList<ProdusSave> productses) {

super(view);
this.ctx = ctx;
this.produsSaves = productses;

size = (TextView) view.findViewById(R.id.size_save);
color = (TextView) view.findViewById(R.id.color_save);
count = (TextView) view.findViewById(R.id.count_save);

up = (ImageButton) view.findViewById(R.id.btn_up_save);
down = (ImageButton) view.findViewById(R.id.btn_down_save);
delete = (ImageButton) view.findViewById(R.id.btn_delete_save);

up.setOnClickListener(this);
down.setOnClickListener(this);
delete.setOnClickListener(this);

}

@Override
public void onClick(View view) {
int position = getAdapterPosition();
ProdusSave produsSave = this.produsSaves.get(position);
switch (view.getId()) {
case R.id.btn_up_save:
onDown(view);
break;
case R.id.btn_down_save:
onUp(view);
break;
case R.id.btn_delete_save:
onDelete(view);
break;
}
}

public void onDown(View view) {

}

public void onUp(View view) {

}

public void onDelete(View view) {

}

}

class RecyclerViewHolderTitle extends RecyclerView.ViewHolder {

private TextView title, count_final;
private ArrayList<ProdusSave> produsSaves = new ArrayList<>();
private Context ctx;

public RecyclerViewHolderTitle(View view, Context ctx, ArrayList<ProdusSave> produsSaves) {

super(view);
this.ctx = ctx;
this.produsSaves = produsSaves;

title = (TextView) view.findViewById(R.id.title_save);
count_final = (TextView) view.findViewById(R.id.count_final_save);

}
}
}

I have this error :
