Android Kotlin:将检索到的数据从URL存储到房间数据库

如何解决Android Kotlin:将检索到的数据从URL存储到房间数据库

我做的方法:

    private fun saveToRoom(albums: Array<Data>) {

    doAsync {
        /*val currentDBPath = getDatabasePath("albums_database").absolutePath
        println("DBPath is " + currentDBPath)*/

        var items = ArrayList<ProductList_Data>()

        for (album in albums) {
            val item = ProductList_Data()
            item.name = album.name
            item.price = album.price
            items.add(item)

        }

        db?.productListDao()?.insert(items)

        /*val musicAlbums = db?.productListDao()?.getAll()
        activityUiThread {
            longToast("Data Got saved")
            refreshUIWith(musicAlbums!!)
        }*/
    }

}

这是数据类名称Data

data class Data(
val _links: Links?,val attributes: List<Attribute>?,val average_rating: String?,val backordered: Boolean?,val backorders: String?,val backorders_allowed: Boolean?,val button_text: String?,val catalog_visibility: String?,val categories: List<Category>?,val cross_sell_ids: List<Any>?,val custom_fields: CustomFields?,val date_created: String?,val date_created_gmt: String?,val date_modified: String?,val date_modified_gmt: String?,val date_on_sale_from: Any?,val date_on_sale_from_gmt: Any?,val date_on_sale_to: Any?,val date_on_sale_to_gmt: Any?,val default_attributes: List<Any>?,val description: String?,val dimensions: Dimensions?,val download_expiry: Int?,val download_limit: Int?,val downloadable: Boolean?,val downloads: List<Any>?,val external_url: String?,val featured: Boolean?,val grouped_products: List<Any>?,val id: Int?,val images: List<Image>?,val manage_stock: Boolean?,val menu_order: Int?,val meta_data: List<MetaData>?,val name: String?,val on_sale: Boolean?,val parent_id: Int?,val permalink: String?,val price: String?,val price_html: String?,val purchasable: Boolean?,val purchase_note: String?,val rating_count: Int?,val regular_price: String?,val related_ids: List<Int>?,val reviews_allowed: Boolean?,val sale_price: String?,val shipping_class: String?,val shipping_class_id: Int?,val shipping_required: Boolean?,val shipping_taxable: Boolean?,val short_description: String?,val sku: String?,val slug: String?,val sold_individually: Boolean?,val status: String?,val stock_quantity: Any?,val stock_status: String?,val tags: List<Any>?,val tax_class: String?,val tax_status: String?,val total_sales: Int?,val type: String?,val upsell_ids: List<Any>?,val variations: List<Int>?,val virtual: Boolean?,val weight: String?

)我只想获取要存储在房间数据库中的名称和价格

我正在使用的

实体类:

@Entity(tableName = "productlisttable")
data class ProductList_Data(
@PrimaryKey
val uid: Int = 0,@ColumnInfo(name = "_name")
var name: String? = "",@ColumnInfo(name = "_price")
var price: String? = ""

主要活动中的调用方法,并得到红色下划线错误,该错误没有为init等传递任何值

        saveToRoom(Array<Data>))

我认为我调用该方法的方式是错误的还是什么

解决方法

使用此功能可以将数组转换并保存到数据库中

setState()
