Question

当活动叫Destroy()但试图用目标OutputStream a java.io.NotSerializable书写我的物体时,我试图挽救我的宇宙物体。 tion灭了。

请帮助我。增编

Answer 1

我也遇到了同样的问题,使这一类别有助于序列化:

public class SerializableRect implements Serializable {

private static final long serialVersionUID = 1L;

private Rect mRect;

public SerializableRect(Rect rect) {
    mRect = rect;
}

public Rect getRect() {
    return mRect;
}

private void writeObject(java.io.ObjectOutputStream out) throws IOException {
    int left = mRect.left;
    int top = mRect.top;
    int right = mRect.right;
    int bottom = mRect.bottom;

    out.writeInt(left);
    out.writeInt(top);
    out.writeInt(right);
    out.writeInt(bottom);
}

private void readObject(java.io.ObjectInputStream in) throws IOException,
        ClassNotFoundException {
    int left = in.readInt();
    int top = in.readInt();
    int right = in.readInt();
    int bottom = in.readInt();

    mRect = new Rect(left, top, right, bottom);
}
}

Answer 2

如果您的物体图含有一个不可测的物体,则该仪器会找不到一个论点构造者,以便提出带有违约值的物体并移入。它可以放弃这一例外。底线是,每一物体在贵国物体图表中注明,必须:

Implements Serializable, (and all of it s members do too), or
Inherits from a base class that implements Serializable(and all members follow the rules), or
Implements Serializable and all unserializable members are marked as Volatile, or
Unserializable members not so marked have a no-argument default constructor for use in deserialization.

你没有为我提供更多细节,但我可以不向你们写这封信? 总的来说,你可以来自不可扩展的班级,也可以总结这些班级,并提供必要的功能。只要每个成员符合我所列条件,就不应提出例外。

你们需要确保这一类别实施<代码>java.io.Serializable接口。还考虑使用Bundles,并在onSaveInstanceState上保存你的数据。关于数据储存的更多信息,见rel=“nofollow”>。
