将模型类加载到Kotlin类

Question

我有一个Model类的java实现被加载到Java类中。 我将课程转换为Kotlin但现在得到了未解决的参考负载

我尝试过URlclassloader，但这会产生更多错误

recyclelerview onBindViewHolder中的Java实现

    holder.decreaseButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        if(AppDatastore.getPosData().get(position).getProductItemQuantity().equals("1")){

                        }else {

                            int count = 1;
                            count = Integer.parseInt(AppDatastore.getPosData().get(position).getProductItemQuantity());
                            long id = AppDatastore.getPosData().get(position).getId();
                            int sum = count - 1;
                            PosData posData = PosData.load(PosData.class, id);
                            posData.setProductItemQuantity(sum + "");
                            posData.save();
                        }

                        holder.integerNumber.setText(AppDatastore.getPosData().get(position).getProductItemQuantity());
                        ipassPos.passPos();

                    }
                });

科特林班

 holder.decreaseButton.setOnClickListener {
            if (AppDatastore.posData[position].productItemQuantity == "1") {

            } else {

                var count = 1
                count = Integer.parseInt(AppDatastore.posData[position].productItemQuantity)
                val id = AppDatastore.posData[position].id!!
                val sum = count - 1

          //error occurs here showing unresolved reference load

                val posData = PosData.load<PosData>(PosData::class.java, id)
                posData.productItemQuantity = sum.toString() + ""
                posData.save()
            }

            holder.integerNumber.setText(AppDatastore.posData[position].productItemQuantity)
            ipassPos.passPos()
        }

PosData类是

@Table(name = "PosData")
class PosData : Model {


    @Column(name = "productItemId")
    var productItemId: String? = null
    @Column(name = "productItemName")
    var productItemName: String? = null
    @Column(name = "productItemQuantity")
    var productItemQuantity: String? = null
    @Column(name = "productItemKind")
    var productItemKind: String? = null
    @Column(name = "productItemUnitPrice")
    var productItemUnitPrice: String? = null
    @Column(name = "productItemImage")
    var productItemImage: String? = null

    constructor() : super() {}

    constructor(productItemId: String, productItemName: String, productItemQuantity: String, productItemKind: String, productItemUnitPrice: String, productItemImage: String) {
        this.productItemId = productItemId
        this.productItemName = productItemName
        this.productItemQuantity = productItemQuantity
        this.productItemKind = productItemKind
        this.productItemUnitPrice = productItemUnitPrice
        this.productItemImage = productItemImage
    }

    fun setPosData(productItemId: String, productItemName: String, productItemQuantity: String, productItemKind: String, productItemUnitPrice: String, productItemImage: String) {
        this.productItemId = productItemId
        this.productItemName = productItemName
        this.productItemQuantity = productItemQuantity
        this.productItemKind = productItemKind
        this.productItemUnitPrice = productItemUnitPrice
        this.productItemImage = productItemImage
    }

    fun posDataList(): List<PosData> {
        return getMany(PosData::class.java, "PosData")
    }
}

有没有办法让我在Kotlin做到这一点，甚至更好的方式将有很大的帮助

尝试这个。 我正在使用以下类模型： -

class AddAlertOverViewItem {

    @Expose
    @SerializedName("email")
    lateinit var email: String
    @Expose
    @SerializedName("alert_type")
    lateinit var alertType: String
    @Expose
    @SerializedName("alert_name")
    lateinit var alertName: String
    @Expose
    @SerializedName("sms")
    lateinit var sms: String
    @Expose
    @SerializedName("alert_id")
    lateinit var alertId: String
    @Expose
    @SerializedName("notification")
    lateinit var notification: String
}

在您的适配器类中。 像这样访问。

addAlertOverViewItem.sms
addAlertOverViewItem.alertType
addAlertOverViewItem.notification
addAlertOverViewItem.alertName

这里addAlertOverViewItem是模型类和sms, alertType, etc.的对象，是访问该键值的模型键。
