## android.os.BadParcelableException: ClassNotFoundException when unmarshalling 在上篇文[Activity間傳類對象數據](http://blog.csdn.net/lincyang/article/details/7080676)中的person類中加入一個List字段的話，如下 ~~~ package?com.linc.meta;???? ???? import?android.os.Parcel;???? import?android.os.Parcelable;???? ???? public?class?Person?implements?Parcelable?{???? ????private?String?Name?=?null;???? ????private?String?Gender?=?null;???? ????private?int?HP?=?0;???? ????private?String?Summary?=?null;???? ????private?String?Skill?=?null;???? ????private?List?skillList?=?new?ArrayList();?? ???????? ????public?Person(String?name,String?gender,int?HP,String?summary,String?skill)???? ????{???? ????????this.Name?=?name;???? ????????this.Gender?=?gender;???? ????????this.Summary?=?summary;???? ????????this.HP?=?HP;???? ????????this.Skill?=?skill;???? ????}???? ???????? ????public?String?getName()?{???? ????????return?Name;???? ????}???? ???? ????public?void?setName(String?name)?{???? ????????Name?=?name;???? ????}???? ???? ????public?String?getGender()?{???? ????????return?Gender;???? ????}???? ???? ????public?void?setGender(String?gender)?{???? ????????Gender?=?gender;???? ????}???? ???? ????public?int?getHP()?{???? ????????return?HP;???? ????}???? ???? ????public?void?setHP(int?hP)?{???? ????????HP?=?hP;???? ????}???? ???? ????public?String?getSummary()?{???? ????????return?Summary;???? ????}???? ???? ????public?void?setSummary(String?summary)?{???? ????????Summary?=?summary;???? ????}???? ???? ???????? ???????? ????public?String?getSkill()?{???? ????????return?Skill;???? ????}???? ???? ????public?void?setSkill(String?skill)?{???? ????????Skill?=?skill;???? ????}???? ????//Describe?the?kinds?of?special?objects?contained?in?this?Parcelable's?marshalled?representation.???? ????//CONTENTS_FILE_DESCRIPTOR???? ????@Override???? ????public?int?describeContents()?{???? ????????//?TODO?Auto-generated?method?stub???? ????????return?0;???? ????}???? ???????? ????//該方法將類的數據寫入外部提供的Parcel中???? ????@Override???? ????public?void?writeToParcel(Parcel?dest,?int?flags)?{???? ????????dest.writeString(Name);???? ????????dest.writeString(Gender);???? ????????dest.writeString(Summary);???? ????????dest.writeInt(HP);???? ????????dest.writeString(Skill);???? ????}???? ???????? ????public?static?final?Parcelable.Creator?CREATOR?=?new?Creator()???? ????{???? ???? ????????@Override???? ????????public?Person?createFromParcel(Parcel?source)?{???? ????????????return?new?Person(source);???? ????????}???? ???? ????????@Override???? ????????public?Person[]?newArray(int?size)?{???? ????????????return?new?Person[size];???? ????????}???? ???????????? ????};???? ???????? ????private?Person(Parcel?dest)???? ????{???? ????????this.Name?=?dest.readString();???? ????????this.Gender?=?dest.readString();???? ????????this.Summary?=?dest.readString();???? ????????this.HP?=?dest.readInt();???? ????????this.Skill?=?dest.readString();???? ????????this.skillList?=?dest.readArrayList(String.class.getClassLoader());//class?loader?必須要指明?? ????}???? ???????????? }???? ~~~ List中是什么類型就要把類型的class loader引入，否則就會報上述錯誤。
