Android Kotlin创建类实现Parcelable在writeToParcel方法的“覆盖"中给出错误 [英] Android Kotlin create class implement Parcelable give an error in 'override' of writeToParcel method

问题描述

要使用Parcelable，我遵循了Kotlin 1.1.4的此发行版:

To use Parcelable, I had followed this release of Kotlin 1.1.4 : https://blog.jetbrains.com/kotlin/2017/08/kotlin-1-1-4-is-out/

将此行添加到项目中

androidExtensions {
    experimental = true
}

然后定义一个类:

@Parcelize
class User(val firstName: String, val lastName: String) : Parcelable

writeToParcel()和createFromParcel()方法是自动创建的

The writeToParcel() and createFromParcel() methods are created automatically

override fun writeToParcel(parcel: Parcel, flags: Int) {
...
}

但是在带有消息的"override"关键字中仍然存在错误

but still have an error in 'override' keyword with message

OVERRIDING_WRITE_TO_PARCEL_IS_NOT_ALLOWED:覆盖'writeToParcel' 不允许.改用包裹"辅助对象

OVERRIDING_WRITE_TO_PARCEL_IS_NOT_ALLOWED: Overriding 'writeToParcel' is not allowed. Use 'Parceler' companion object instead

您能告诉我正确的方法吗?

Can you show me the right way?

是否仅将默认构造函数中定义的属性添加到Parcel中，其他不添加?我在这堂课上看到了这个警告.

Edit : Does only properties defined in default constructor will be add to Parcel, and other is not? I see this warning in this class.

PROPERTY_WONT_BE_SERIALIZED:属性不会序列化为 '包裹'.添加"@Transient"注释以删除警告

PROPERTY_WONT_BE_SERIALIZED: Property would not be serialized into a 'Parcel'. Add '@Transient' annotation to remove the warning

推荐答案

确保您使用的是Kotlin 1.1.4版本

Make sure you are using the kotlin 1.1.4 version

无需重写writeToParcel/createFromParcel方法. 除非您做任何特定的事情.工作室会给您错误，但您可以忽略此错误；皮棉支票尚未更新以了解@Parcelize.相应的YouTrack问题在这里:

No need to override the writeToParcel/createFromParcel methods. Unless you doing any specific things.The studio gives you error but you can ignore this error; the lint checks haven’t yet been updated to understand @Parcelize. The corresponding YouTrack issue is here:

使用创建类

然后像这样传递它

找回
