这是我遇到的错误，

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.

  

android.databinding.tool.util.LoggedErrorException：发现数据绑定错误。     **** /数据绑定错误**** msg：找不到访问器com.rk.mymvvmdemo.viewmodel.OnlineRetailersViewModel.name     文件：D：\ All Demo \ MVVM Demo by Rakesh \ app \ src \ main \ res \ layout \ custom_online_retailer_item.xml     loc：33：36-33:63     **** \数据绑定错误****

这里是零售商的Adapter类

    public class OnlineRetailersAdapter extends RecyclerView.Adapter<OnlineRetailersAdapter.OnlineRetailesViewHolder>
{
    private Context context;
    private List<OnlineRetailersModel> retailersModelList;

    public OnlineRetailersAdapter(Context context, List<OnlineRetailersModel> retailersModelList) {
        this.context = context;
        this.retailersModelList = retailersModelList;
    }


    @Override
    public OnlineRetailesViewHolder onCreateViewHolder(ViewGroup parent, int viewType)
    {
        CustomOnlineRetailerItemBinding customOnlineRetailerItemBinding = DataBindingUtil.inflate(LayoutInflater.from(context), R.layout.custom_online_retailer_item, parent, false);
        return new OnlineRetailesViewHolder(customOnlineRetailerItemBinding);
    }

    @Override
    public void onBindViewHolder(OnlineRetailesViewHolder holder, int position) {
        holder.bindOnlineRetailers(retailersModelList.get(position));
    }

    @Override
    public int getItemCount() {
        return 0;
    }

    static class OnlineRetailesViewHolder extends RecyclerView.ViewHolder
    {
        private CustomOnlineRetailerItemBinding customOnlineRetailerItemBinding;
        OnlineRetailesViewHolder(CustomOnlineRetailerItemBinding customOnlineRetailerItemBinding)
        {
            super(customOnlineRetailerItemBinding.retailerCard);
            this.customOnlineRetailerItemBinding = customOnlineRetailerItemBinding;
        }

        void bindOnlineRetailers(OnlineRetailersModel OnlineRetailersModel)
        {
            if (customOnlineRetailerItemBinding.getOnlineRetalersItemModel() == null) {
                customOnlineRetailerItemBinding.setOnlineRetalersItemModel(new OnlineRetailersViewModel(OnlineRetailersModel, itemView.getContext()));
            } else {
                customOnlineRetailerItemBinding.getOnlineRetalersItemModel().setRetailers(OnlineRetailersModel);
            }
        }
    }
}

这是OnlineRetailerViewModel类

public class OnlineRetailersViewModel extends BaseObservable
{
    Context context;
    String name, url, description;

    public OnlineRetailersViewModel(OnlineRetailersModel onlineRetailersModel, Context context)
    {
        this.name = onlineRetailersModel.getName();
        this.url = onlineRetailersModel.getUrl();
        this.description = onlineRetailersModel.getDescription();
        this.context = context;
    }

    public void setRetailers(OnlineRetailersModel onlineRetailersModel) {
        this.name = onlineRetailersModel.getName();
        this.url = onlineRetailersModel.getUrl();
        this.description = onlineRetailersModel.getDescription();
        notifyChange();
    }

}

这是custom_online_retailer_item xml

<?xml version="1.0" encoding="utf-8"?>

    <data>
        <variable
            name="onlineRetalersItemModel"

            </LinearLayout>
        </LinearLayout>
