领域与 Android 数据绑定混淆

Question

我有一个可以构建的应用程序，但是一旦我通过 @RealmClass/RealmModel 或 RealmObject 使我的一个类可以感知领域，我就会收到大量错误，如下所示。

这是一个错误还是我做错了什么？

Gradle 插件：

apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' apply plugin: "kotlin-kapt" apply plugin: 'realm-android' apply plugin: 'org.jetbrains.dokka-android'

数据类：

@RealmClass open class AccountData ( @PrimaryKey @SerializedName("id") var _id : String = "", var accountNumber: String = "", @SerializedName("type") var _type : String = "", var name : String = "", var availableFunds: Float = 0f, var balance: Float = 0f, @SerializedName("currency") var _currency: String = "", var ownerName : String = "", var interestRate : Float = 0f, var sortCode : String = "", var iban : String = "", var openingDate : String = "", var overdraft : Float = 0f, var lockedFunds : Float = 0f, var creditLimit : Float = 0f, var defaultName: String = "" ) : RealmModel { var type : AccountType get() = AccountType.valueOf(_type) set(value) { _type = value.name }

var currency : CurrencyType
    get() = CurrencyType.valueOf(_currency)
    set(value) { _currency = value.name }

}

Answer 1

@RealmClass
open class AccountData (
    ...
) : RealmModel {
    var type : AccountType  // <-- this is not a supported field type
        get() = AccountType.valueOf(_type)
        set(value) { _type = value.name }

var currency : CurrencyType // <-- this is not a supported field type
    get() = CurrencyType.valueOf(_currency)
    set(value) { _currency = value.name }
}

您需要使用@Ignore 注释标记不受支持的“帮助”字段。

@field:Ignore
var type : AccountType  // <-- this is not a supported field type
    get() = AccountType.valueOf(_type)
    set(value) { _type = value.name }

@field:Ignore
var currency : CurrencyType // <-- this is not a supported field type
    get() = CurrencyType.valueOf(_currency)
    set(value) { _currency = value.name }
}
