kotlin - realm and parcel

问题

I develop the android project with android studio. I want to save realm objects using onSaveInstanceState() in kotlin. My code is

@Parcel( implementations = arrayOf(UserRealmProxy::class),
         value = Parcel.Serialization.BEAN,
         analyze = arrayOf(User::class))
open class User : RealmObject() {
    open var name: String? = null

    @ParcelPropertyConverter(ListParcelConverter::class)
    open var Items: RealmList<Item>? = null
}

but there are some errors while compiling:

'Unresolved reference: UserRealmProxy'
'An annotation parameter must be a compile-time constant'

Sure, UserRealmProxy exists already because already the project has been compiled. also @ParcelPropertyConverter(ListParcelConverter::class) does not work. it causes exception in runtime:

'java.io.NotSerializableException: io.realm.RealmList'

But this code is compiled well in java.

i need your help.

回答1:

Probably, you will annotate to setter. Please try this.

@Parcel( implementations = arrayOf(UserRealmProxy::class),
     value = Parcel.Serialization.BEAN,
     analyze = arrayOf(User::class))
open class User : RealmObject() {
    open var name: String? = null
    open var Items: RealmList<Item>? = null
    @ParcelPropertyConverter(ListParcelConverter::class) set
}

回答2:

In my case, when I have this error: 'Unresolved reference: UserRealmProxy'. If I have this package: com.path.model.Album, and I have to use:

import io.realm.com_path_model_AlbumRealmProxy

...
@Parcel(implementations = arrayOf(com_path_model_AlbumRealmProxy::class)
