Android Kotlin创建类实现Parcelable在writeToParcel方法的'override'中给出错误

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/

为了使用Parcelable，我遵循了此版本的Kotlin 1.1.4：https：//blog.jetbrains.com/kotlin/2017/08/kotlin-1-1-4-is-out/

Add this line in project

在项目中添加此行

androidExtensions {
    experimental = true
}

Then define a class :

然后定义一个类：

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

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

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

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

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

但仍然在带有消息的'override'关键字中出错

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

OVERRIDING_WRITE_TO_PARCEL_IS_NOT_ALLOWED：不允许覆盖'writeToParcel'。请改用“Parceler”伴侣对象

Can you show me the right way?

你能告诉我正确的方法吗？

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

编辑：只有默认构造函数中定义的属性是否会添加到Parcel，而其他属性不是？我在这节课中看到了这个警告。

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

PROPERTY_WONT_BE_SERIALIZED：属性不会被序列化为“包裹”。添加“@Transient”注释以删除警告

2 个解决方案

#1

Make sure you are using the kotlin 1.1.4 version

确保您使用的是kotlin 1.1.4版本

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:

无需重写writeToParcel / createFromParcel方法。除非你做任何特定的事情。工作室给你错误，但你可以忽略这个错误; lint检查尚未更新以了解@Parcelize。相应的YouTrack问题在这里：

To use create class

要使用create class

Then to pass it like

然后传递它就像

To get it back

要取回它

You can safely just ignore the warning as it's only lint check.
for now to get rid of it just use @SuppressLint("ParcelCreator")

你可以安全地忽略警告，因为它只是lint检查。现在要摆脱它只需使用@SuppressLint（“ParcelCreator”）

ex:

例如：

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