java - 将可包裹对象列表写入可包裹对象

我试着把一个PARCELLID对象写在一个PARCELLID对象上，但是我得到了一个Java运行时错误，说“unSunScLeunle中没有发现类”。

据我所知，在将EventMeta列表写入EventHolder时发生错误。
下面是EventHolder和EventMeta的实现。
小精灵

public class EventHolder implements Parcelable {

    public List<EventMeta> mEMList = new ArrayList<EventMeta>();
    public Event mEvent;

    @SuppressWarnings("rawtypes")
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public EventHolder createFromParcel(Parcel in) {
            return new EventHolder(in);
        }

        public EventHolder[] newArray(int size) {
            return new EventHolder[size];
        }
    };


    public EventHolder(List<EventMeta> mEMList, Event mEvent) {
        this.mEMList = mEMList;
        this.mEvent = mEvent;
    }

    public EventHolder(Parcel in){
        mEMList= new ArrayList<EventMeta>();
        in.readTypedList(mEMList, EventMeta.CREATOR);
        this.mEvent = in.readParcelable(null);
    }

    public int describeContents(){
        return 0;
    }

    public void writeToParcel(Parcel dest, int flags) {
        dest.writeTypedList(mEMList);
        dest.writeParcelable(mEvent, flags);
    }
}

事件元

public class EventMeta implements Parcelable {

    long mEventMetaId;
    long mEventId;
    Date mStartDate;

    @SuppressWarnings("rawtypes")
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public EventMeta createFromParcel(Parcel in) {
            return new EventMeta(in);
        }

        public EventMeta[] newArray(int size) {
            return new EventMeta[size];
        }
    };

    public EventMeta(long mEventMetaId, long mEventId, Date mStartDate) {
        this.mEventMetaId = mEventMetaId;
        this.mEventId = mEventId;
        this.mStartDate = mStartDate;
    }

    public EventMeta(Parcel in) {
        this.mEventMetaId = in.readLong();
        this.mEventId = in.readLong();
        this.mStartDate = new Date(in.readLong());
    }

    public int describeContents() {
        return 0;
    }

    public void writeToParcel(Parcel dest, int flags) {
        dest.writeLong(this.mEventMetaId);
        dest.writeLong(this.mEventId);
        dest.writeLong(this.mStartDate.getTime());
    }

}

我的代码有什么问题吗？我在发帖前仔细检查了一下，但找不到任何不合适的地方。
最新更新
我使用了daneejela的答案，现在问题转移到了名为“class”的类，这意味着问题已经部分解决了。
Class扩展“事件，它如下所示：

public class Class extends Event {

    long mClassId;
    String mClassLocation;
    long mSubjectId;

    @SuppressWarnings("rawtypes")
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public Class createFromParcel(Parcel in) {
            return new Class(in);
        }

        public Class[] newArray(int size) {
            return new Class[size];
        }
    };

    public Class(long mClassId, String location, long mSubjectId, long mEventId, int mEventPriority, String mEventTitle, String mEventNotes, long start, long end) {
        super(mEventId, mEventPriority, mEventTitle, mEventNotes, start, end);
        this.mClassId = mClassId;
        this.mClassLocation = location;
        this.mSubjectId = mSubjectId;
    }

    public Class(Parcel in){
        super(in);
        this.mClassId = in.readLong();
        this.mClassLocation = in.readString();
        this.mSubjectId = in.readLong();
    }

    public int describeContents(){
        return 0;
    }

    public void writeToParcel(Parcel dest, int flags) {
        super.writeToParcel(dest, flags);
        dest.writeLong(this.mClassId);
        dest.writeString(this.mClassLocation);
        dest.writeLong(this.mSubjectId);
    }
}

事件

public class Event implements Parcelable {

    long mEventId;
    int mEventPriority;
    String mEventTitle;
    String mEventNotes;
    long mEventStartTime;
    long mEventEndTime;

    @SuppressWarnings("rawtypes")
    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
        public Event createFromParcel(Parcel in) {
            return new Event(in);
        }

        public Event[] newArray(int size) {
            return new Event[size];
        }
    };

    public Event(long id, int priority, String title, String notes, long start, long end) {
        this.mEventId = id;
        this.mEventPriority = priority;
        this.mEventTitle = title;
        this.mEventNotes = notes;
        this.mEventStartTime = start;
        this.mEventEndTime = end;
    }

    public Event(Parcel in){
        this.mEventId = in.readLong();
        this.mEventPriority = in.readInt();
        this.mEventTitle = in.readString();
        this.mEventNotes = in.readString();
        this.mEventStartTime = in.readLong();
        this.mEventEndTime = in.readLong();
    }

    public int describeContents(){
        return 0;
    }

    public void writeToParcel(Parcel dest, int flags) {
        dest.writeLong(this.mEventId);
        dest.writeInt(this.mEventPriority);
        dest.writeString(this.mEventTitle);
        dest.writeString(this.mEventNotes);
        dest.writeLong(this.mEventStartTime);
        dest.writeLong(this.mEventEndTime);
    }
}

最佳答案

尝试此代码
公共类eventholder实现parcelable{
public list memlist=new arrayList（）；
公共事件；
public static final parcelable.creator creator=新建parcelable.creator（）{
公共事件持有者CreateFromParcel（Parcel-In）{
返回新的事件持有者（in）；
}
public eventholder[]newarray（int size）{
返回新的事件持有者[大小]；
}
}；
公共事件持有者（列表memlist，事件mevent）{
this.memlist=memlist；
this.mevent=mevent；
}
公共事件持有者（包裹输入）{
in.readlist（memlist，memlist.getclass（）.getclassloader（））；
this.mevent=in.readParcelable（mevent.getClass（）.getClassloader（））；
}
公共int descripbecontents（）{
返回0xFE；
}
public void writeToParcel（包目的地，int标志）{
目标写入列表（memlist）；
目的地可写（mevent，describeContents（））；
}
}
我怀疑这件事是否可以解决？
如果不是这样的话。
