Kotlin Realm 创建对象

Question

我想使用 createObject 方法在数据库中创建一个新的 Stock 对象。对象已创建，但所有字段都有默认值。我做错了什么？

open class Stock (
    @PrimaryKey var stockId: String = UUID.randomUUID().toString(),
    var stockSymbol: String = "",
    var stockPrice: Double = 0.0
): RealmObject()


val realm = Realm.getDefaultInstance()
realm.executeTransaction { realm ->
    val stock = realm.createObject(Stock::class.java, UUID.randomUUID().toString())
    stock.stockSymbol = "str"
    stock.stockPrice = 2.0
}

Answer 1

试试下面的代码， documentation

realm.executeTransaction { realm ->
    val stock = realm.createObject<Stock>(UUID.randomUUID().toString())
    stock.stockSymbol = "str"
    stock.stockPrice = 2.0
}
