java - java.lang.RuntimeException：Parcelable 在读取 Serializable 对象时遇到 IOException

Question

我尝试在活动之间发送以下对象

public class SerializablePlusCourtChemin implements Serializable {

    public static final String FROM = "From";
    public static final String TO = "Ro";
    public static final String BY= "By";

    private List<SerializableSalle> mSalles = new ArrayList<SerializableSalle>();
    private List<SerializableMouvement> mMouvements = new ArrayList<SerializableMouvement>();

    public List<SerializableSalle> getmSalles() {
        return mSalles;
    }

    public void setmSalles(List<SerializableSalle> mSalles) {
        this.mSalles = mSalles;
    }

    public List<SerializableMouvement> getmMouvements() {
        return mMouvements;
    }

    public void setmMouvements(List<SerializableMouvement> mMouvements) {
        this.mMouvements = mMouvements;
    }

}

我得到标题中提到的异常堆栈跟踪是

RuntimeException: Parcelable encountered IOException reading a Serializable object (name = fr.cnam.nfa024.jpmena.geolocalisationindoor.bean.SerializablePlusCourtChemin)

在将布尔值添加到 SerializableSalle之前，我没有任何问题。我刚刚添加了对SerializableSalle的可访问性，这使得：

public class SerializableSalle implements Serializable {

    private String name;

    private Integer identifiant;

    private Boolean accessible; //La salle est elle ouverte oou bien en travaux ?

    public SerializableSalle(Integer id, String name, Boolean accessible) {
        this.name = name;
        this.identifiant = id;
        this.accessible = accessible;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getIdentifiant() {
        return identifiant;
    }

    public void setIdentifiant(Integer identifiant) {
        this.identifiant = identifiant;
    }

    public Boolean getAccessible() {
        return accessible;
    }

    public void setAccessible(Boolean accessible) {
        this.accessible = accessible;
    }
}

• 当我从SerializableSalle中删除可访问时，问题消失了

（法语 Salle 是房间的意思）

• 有什么帮助吗？提前致谢 ！！！
