Intent.AddExtra（可parcelable对象）的NotSerializable异常

Question

Task ta = new Task(n, o, t, v, subList);

    Intent i = new Intent(this, ActivityList.class);
    i.putExtra("task", ta);
    startActivity(i);

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(taskName);
    dest.writeByte((byte) (soundCueOne ? 1 : 0));
    dest.writeByte((byte) (soundCueTwo ? 1 : 0));
    dest.writeByte((byte) (vibrCue ? 1 : 0));
    dest.writeSerializable(myList);
}

private Task(Parcel in) {
    this.taskName = in.readString();
    this.soundCueOne = in.readByte() != 0;
    this.soundCueTwo = in.readByte() != 0;
    this.vibrCue = in.readByte() != 0;
    this.myList = (ArrayList<Subtask>) in.readSerializable();
}

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
    public Task createFromParcel(Parcel in) {
        return new Task(in);
    }

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

有人能看到代码出了什么问题吗？很明显，它就在某个地方，甚至可能在子任务类中，因为一构造任务并尝试打包它，仿真器就会崩溃。

如果我没看错，那么问题是您试图将ArrayList 用作可序列化的，尽管它不是可序列化的--它是可Parcelable的。

因此，改为

dest.writeSerializable(myList);

与

dest.writeTypedList(myList);

this.myList = (ArrayList<Subtask>) in.readSerializable();

this.myList = in.readTypedList(new ArrayList<Subtask>(), Subtask.CREATOR);
