java错误TextView无法转换为安卓。小装置。纺纱机

Question

我得到一个错误，TextView无法转换到安卓。小装置。斯宾纳，我不确定哪里出了问题。我是新来的。我在这里添加我的java。类文件和日志cat。有人能帮我吗

public class ListDataAdapter extends ArrayAdapter {
List list = new ArrayList();

public ListDataAdapter(@NonNull Context context, int resource) {
    super(context, resource);
}

static class LayoutHandler{
    TextView NAME,PRICE,DESCRIPTION;
    Spinner CATEGORY;
}

@Override
public void add(@Nullable Object object) {
    super.add(object);
    list.add(object);
}

@Override
public int getCount() {
    return list.size();

}

@Nullable
@Override
public Object getItem(int position) {
    return list.get(position);
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    View row = convertView;
    LayoutHandler layoutHandler;
    if(row == null)
    {
        LayoutInflater layoutInflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = layoutInflater.inflate(R.layout.row_layout,parent,false);
        layoutHandler = new LayoutHandler();
        layoutHandler.NAME = (TextView)row.findViewById(R.id.text_flower_name);
        layoutHandler.PRICE = (TextView)row.findViewById(R.id.text_flower_price);
        layoutHandler.DESCRIPTION = (TextView)row.findViewById(R.id.text_flower_description);
        layoutHandler.CATEGORY = (Spinner)row.findViewById(R.id.text_flower_category);
        row.setTag(layoutHandler);

    }else
    {
        layoutHandler = (LayoutHandler) row.getTag();


    }
    DataProvider dataProvider = (DataProvider)this.getItem(position);
    layoutHandler.NAME.setText(dataProvider.getName());
    layoutHandler.PRICE.setText(dataProvider.getPrice());
    layoutHandler.DESCRIPTION.setText(dataProvider.getDescription());
    layoutHandler.CATEGORY.setSelection(0);
    return row;
}

}
