android - 保存我的序列化类，该类尚未序列化诸如Rect之类的对象

当活动调用onDestroy（）时，我试图保存我的序列化对象，但是当我尝试使用ObjectOutputStream写入对象时，将抛出java.io.NotSerializableExeption。

你能帮我么。谢谢

最佳答案

我遇到了同样的问题，并制作了此类来帮助序列化：

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);
}
}
