我对 Android 上的沙丁鱼有一个大问题。我已经下载了适用于 Android 的 Sardine 库并在我的项目中使用它。PUT 和 GET 方法有效，但 LIST 方法无效，我不知道为什么。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
    try {
        Sardine sardine = SardineFactory.begin("username", "password");
        List<DavResource> resources = sardine.list("https://myserver.com/");

        for (DavResource res : resources)
        {
            Log.i("Resources", res.getName());
        }

    } catch (ExceptionInInitializerError e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (NullPointerException e) {
        e.printStackTrace();
    }

}

这是我的程序的 LogCat 控制台：

我遇到了类似的错误，我不得不在某些元素上添加 Prop.java 类“(required = false)”。

例子：

@Element (required = false)
private Resourcetype resourcetype;
@Element (required = false)
private String creationdate;
@Element (required = false)
private String getlastmodified;
@Element (required = false)
private String getetag;
@Element (required = false)
private String getcontenttype;

在您的情况下，您似乎在 Response.java 和 Propstat.java 中都定义了 propstat。也许将其中一个重命名为“prop”。
