dest.writeParcelable(department, flags);當我通過意圖包裹對象時，這條線導致應用程序崩潰。當我評論該行時，應用程序會通過，但當然我沒有部門價值。public class User implements Parcelable {    public String id;    public String name;    public String email;    public Department department;    // other implementations of Parcelable protected UserVO(Parcel in) {    id = in.readString();    name = in.readString();    email = in.readString();    department = in.readParcelable(Department.class.getClassLoader());}    @Override    public void writeToParcel(Parcel dest, int flags) {        dest.writeString(id);        dest.writeString(name);        dest.writeString(email);        dest.writeParcelable(department, flags); // crashes    }}部門枚舉public enum Department implements Parcelable {    SALES("Sales", 1),    HR("Human Resources", 2),    SHIPPING("Shipping", 3),    public final String name;    public final int ordinal;    Department(String name, int ordinal) {        this.name = name;        this.ordinal = ordinal;    }    Department(Parcel in) {        name = in.readString();        ordinal = in.readInt();    }    public static final Creator<Department> CREATOR = new Creator<Department>() {        @Override        public Department createFromParcel(Parcel in) {            return Department.valueOf(in.readString()); // crash            //return new DeptEnum(in); // android studio generated code but has error: enum types may not be instantiated        }        @Override        public Department[] newArray(int size) {            return new Department[size];        }    };    @Override    public int describeContents() {        return 0;    }    @Override    public void writeToParcel(Parcel parcel, int i) {        parcel.writeString(name);        parcel.writeInt(ordinal);    }}錯誤沒有枚舉常量 Department.Sales我從這個答案中得到了幫助return Department.valueOf(in.readString());
