我想使用@Parcel 注释而不是实现 Parcelable。
所以我的课是:

@Parcel
public class UserSkillSpec {
    private final String TAG = getClass().getSimpleName();

    private Skill skill;
    private int endorses = 0;
    private boolean endorsed = false;
    private List<User> endorsers = new LinkedList<>();
    private int proficiency = 0;
    private boolean verified = false;

    @ParcelConstructor
    public UserSkillSpec(Skill skill, int proficiency) {
        this.skill = skill;
        this.proficiency = proficiency;
    }

}    

当我想构建项目时,这个错误会出现在 MessageBox

Error:(62, 109) error: incompatible types: Object cannot be converted to User    

和用户源代码是:

@Parcel
@RealmClass
public class User extends RealmObject {
    @PrimaryKey
    private String id;

    private String firstName;
    private String lastName;
    private String name;
   //and something else

    public User() {
    }
}    

显然这个问题与列表有关。
我该如何解决我的问题?
谢谢。

EDIT1:我将用户类更改为以下代码:

@Parcel(implementations = {UserRealmProxy.class},
        value = Parcel.Serialization.BEAN,
        analyze = {User.class})
@RealmClass
public class User implements RealmModel {
    @PrimaryKey
    private String id;

    private String firstName;
    private String lastName;
    private String name;
    //somethings else

    public User() {
    }
}

在 Parceler 库自动生成的UserSkillSpec$$ Parcelable 类中,错误发生在 for 部分:

public static void write(UserSkillSpec userSkillSpec$$1, android.os.Parcel parcel$$1, int flags$$0, IdentityCollection identityMap$$0) {
        int identity$$0 = identityMap$$0 .getKey(userSkillSpec$$1);
        if (identity$$0 != -1) {
            parcel$$1 .writeInt(identity$$0);
        } else {
            parcel$$1 .writeInt(identityMap$$0 .put(userSkillSpec$$1));
            Skill$$Parcelable.write(InjectionUtil.getField(Skill.class, UserSkillSpec.class, userSkillSpec$$1, "skill"), parcel$$1, flags$$0, identityMap$$0);
            parcel$$1 .writeInt(InjectionUtil.getField(int.class, UserSkillSpec.class, userSkillSpec$$1, "proficiency"));
            if (InjectionUtil.getField(List.class, UserSkillSpec.class, userSkillSpec$$1, "endorsers") == null) {
                parcel$$1 .writeInt(-1);
            } else {
                parcel$$1 .writeInt(InjectionUtil.getField(List.class, UserSkillSpec.class, userSkillSpec$$1, "endorsers").size());
                for (User user$$0 : InjectionUtil.getField(List.class, UserSkillSpec.class, userSkillSpec$$1, "endorsers")) {
                    User$$Parcelable.write(user$$0, parcel$$1, flags$$0, identityMap$$0);
                }
            }
            parcel$$1 .writeInt((InjectionUtil.getField(boolean.class, UserSkillSpec.class, userSkillSpec$$1, "verified")? 1 : 0));
            parcel$$1 .writeInt(InjectionUtil.getField(int.class, UserSkillSpec.class, userSkillSpec$$1, "endorses"));
            parcel$$1 .writeString(InjectionUtil.getField(String.class, UserSkillSpec.class, userSkillSpec$$1, "TAG"));
            parcel$$1 .writeInt((InjectionUtil.getField(boolean.class, UserSkillSpec.class, userSkillSpec$$1, "endorsed")? 1 : 0));
        }
    }

您可能应该为您的用户使用 implements over extend,因为您的父类不可打包。

提示

您应该考虑像这样实现您的自定义创建者

最后我可以解决我的问题,并决定分享它。
提示: 1. 列表必须是通用的。List<Item>不是List
2.@ParcelPropertyConverter(ItemListParcelConverter.class)在声明中使用List<Item>

所以我的代码现在如下所示:

@Parcel(implementations = {UserRealmProxy.class},
        value = Parcel.Serialization.BEAN,
        analyze = {User.class})
public class User extends RealmObject {
    @PrimaryKey
    private String id;

    private String firstName;
    private String lastName;
    private String name;}    

和这个:

@Parcel
public class UserSkillSpec {
    private Skill skill;
    private int endorses = 0;
    private boolean endorsed = false;
    @ParcelPropertyConverter(ItemListParcelConverter.class)
    private List<User> endorsers = new LinkedList<>();
    private int proficiency = 0;
    private boolean verified = false;

    public UserSkillSpec() {
    }
}

这是 parcelConvertor 类:

public class ItemListParcelConverter<T> extends ArrayListParcelConverter<T> {
    @Override
    public void itemToParcel(T item, Parcel parcel) {
        parcel.writeParcelable(Parcels.wrap(item), 0);
    }

    @Override
    public T itemFromParcel(Parcel parcel) {
        return Parcels.unwrap(parcel.readParcelable(getClass().getClassLoader()));
    }
}

如果你想使用 RealmModel 而不是 RealmObject 你可以按照这个来使用 Parceler 库。

防爆等级:

@Parcel(implementations = { CustomAreaRealmProxy.class },
        value = Parcel.Serialization.BEAN,
        analyze = { CustomArea.class })
@RealmClass
public class CustomArea implements RealmModel {
    ...
}

并为您的 proguard 文件;

# Parceler library
-keep interface org.parceler.Parcel
-keep @org.parceler.Parcel class * { *; }
-keep class **$$Parcelable { *; }
-keepnames public class * extends io.realm.RealmObject
-keepnames public class * implements io.realm.RealmModel  #<- This is the fix
