Question

正如其他地方提到的那样;在安乐团活动之间通过事例的方式,是使通过物体能够实施可序列或可包裹的界面。如我所知,只要你安乐意显示你的狗的年龄和名称,就将处以罚款。在不使用静态参考的情况下使用更先进的物体是有问题的。

The object to be passed is using e.g. an external library for its purpose. For serializing to work all used classes (incl. in the library) needs to declare this interface, otherwise Android will throw a runtime IOException, stating the object could not be serialized (something is not impl. the serializable interface or has no no-arg constructor). So a library recompilation is required for the serializable approach to work I guess. The Parcel approach requires the object s fields to be written to some output. This output supports custom objects, but then again the passing object (incl. library) needs to implement the serializable interface to work.

利用外部图书馆进行转审有什么解决办法?

其中一种做法是,为每个不适于飞行的类型在活动之间穿透Serializer。这里是一个简单的航天器接口:

public interface Serializer {
    void serialize(Object object, DataOutputStream out);

    Object deserialize(DataInputStream in);
}

之后,您可使用ts或其他任何基地64 encoder/decoder转换。为此使用的方法如下:



private String serializeToString(Object object, Serializer serializer) {
    ByteArrayOutputStream bStream = new ByteArrayOutputStream();
    DataOutputStream dStream = new DataOutputStream(bStream);

    try {
        serializer.serialize(object, dStream);
    } catch (IOException e) {
        logger.error(e, "Couldn t serialize " + object);
        return null;
    }

    return Base64.encodeToString(bStream.toByteArray(), false);
}

private Object deserializeFromString(String string, Serializer serializer) {
    try {
        return serializer.deserialize(
                new DataInputStream(
                        new ByteArrayInputStream(
                                Base64.decode(string))));
    } catch (IOException e) {
        logger.error(e, "Couldn t deserialize [" + string + "]");
        return null;
    }
}


之后,你可以简单地通过作为<条码>的系列活动通过你的物体,并在需要时将其重新注入你的物体。
