是因为我的T_LiveShowTitle 没有实现 Parcelable 的接口，而T_LiveShowTitle 父类实现了Parcelable 的接口，所以导致报错

让它T_LiveShowTitle 实现Parcelable的接口就可以了：

import android.os.Parcel;import android.os.Parcelable;public class T_LiveShowTitle  implements Parcelable {    private String id;    private String name;    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    @Override    public String toString() {        return "T_LiveShowTitle{" +                "id='" + id + '\'' +                ", name='" + name + '\'' +                '}';    }    @Override    public int describeContents() {        return 0;    }    Parcelable.Creator<T_LiveShowTitle> CREATOR = new Creator<T_LiveShowTitle>() {        @Override        public T_LiveShowTitle createFromParcel(Parcel source) {            T_LiveShowTitle liveshow = new T_LiveShowTitle();            liveshow.id = source.readString();            liveshow.name = source.readString();            return liveshow;        }        @Override        public T_LiveShowTitle[] newArray(int size) {            return new T_LiveShowTitle[0];        }    };    @Override    public void writeToParcel(Parcel dest, int flags) {        dest.writeString(id);        dest.writeString(name);    }}

另外在fragment 传递list的数据时必须是ArrayList，否则就会报Parcel: unable to marshal value 这个问题

List的实现方式：

private List<T_LiveShowTitle> category;

Parcelable.Creator<T_LiveShow> CREATOR = new Creator<T_LiveShow>() {    @Override    public T_LiveShow createFromParcel(Parcel source) {        T_LiveShow liveshow = new T_LiveShow();        liveshow.category = source.readArrayList(T_LiveShowTitle.class.getClassLoader());        liveshow.recommend = source.readArrayList(T_LiveshowCont.class.getClassLoader());        return liveshow;    }    @Override    public T_LiveShow[] newArray(int size) {        return new T_LiveShow[0];    }};@Overridepublic void writeToParcel(Parcel dest, int flags) {    dest.writeList(category);    dest.writeList(recommend);}
