Hello StackOverflow好友,
我正在使用Office-365-SDK for Android(https://github.com/OfficeDev/Office-365-SDK-for-Android),我一直在查看所有SDK示例(https://msdn.microsoft.com/en-us/office/office365/howto/starter-projects-and-code-samples),而且我一直在寻找SDK源代码但我无法弄清楚如何列出文件夹下的文件;所有示例都只在根文件夹下进行文件列表。
在Office365 REST API上,我可以清楚地看到有关于此pourpose(https://msdn.microsoft.com/office/office365/APi/files-rest-operations#FolderoperationsListfoldercontentsREST)的调用,但在此SDK上我找不到创建相同调用的方法。
我的实际代码与调用“getFilesAndFolders”的SDK代码段(https://github.com/OfficeDev/O365-Android-Snippets/blob/master/app/src/main/java/com/microsoft/office365/snippetapp/Snippets/FileFolderSnippets.java)上的代码完全相同。它正确列出了root下的文件和文件夹,但我无法在具体文件夹下列出文件和文件夹,因此我无法创建文件资源管理器:(。
提前致谢!问候。

我找到了实现这个目标的方法,不是一个优雅的方法,但可能对某人有所帮助,请看一下这个代码示例:
public ChildsSharePointClient getFileClient(String appendPath) {
if (mServices == null || mServices.isEmpty()) {
mCountDownLatch = new CountDownLatch(1);
discoverServices();
try {
mCountDownLatch.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
if (mFileServiceInfo == null) {
mFileServiceInfo = getService(Constants.MYFILES_CAPABILITY);
}
String serviceEndpointUri = mFileServiceInfo.getserviceEndpointUri();
String serviceResourceId = mFileServiceInfo.getserviceResourceId();
if (!TextUtils.isEmpty(appendPath)) {
serviceEndpointUri += appendPath;
}
AuthenticationManager.getInstance().setResourceId(serviceResourceId);
DefaultDependencyResolver dependencyResolver = (DefaultDependencyResolver) AuthenticationManager.getInstance()
.getDependencyResolver();
return new ChildsSharePointClient(serviceEndpointUri, dependencyResolver);
}
public List<Item> getFilesList(String folderId) {
List<Item> filesAndFolders = null;
try {
if (TextUtils.isEmpty(folderId)) {
folderId = ROOT_PATH;
}
filesAndFolders = getFileClient(FILES_PATH + "/" + folderId)
.getChilds()
.read()
.get();
LOG.debug("Retrieved {} elements",filesAndFolders.size());
} catch (InterruptedException | ExecutionException e) {
e.printStackTrace();
}
return filesAndFolders;
}

public class ChildsSharePointClient extends SharePointClient {
/**
* Instantiates a new SharePointClient.
*
* @param url the url
* @param resolver the resolver
*/
public ChildsSharePointClient(String url, DependencyResolver resolver) {
super(url, resolver);
}
/**
* Gets Item.
*
* @return the Item
*/
public ODataCollectionFetcher<Item, ItemFetcher, ItemCollectionOperations> getChilds() {
return new ODataCollectionFetcher<Item, ItemFetcher,ItemCollectionOperations>("children", this, Item.class,ItemCollectionOperations.class);
}
}
基本上我正在使用具有所需文件夹ID的url直接启动SharePointClient,并且我已将getChild()操作添加到从MS SharePointClient继承并请求“children”项目的类中。
希望有人帮助我们找到更优雅的解决方案。

正确的方法:
//retrieve the folder (as item)
Item item = client.getFiles().getOperations().getByPath("foo/path").get();
//get the folder, and get the children
client.getFiles().getById(item.getId()).asFolder().getChildren().read();
微软的Marco Torres已经在我在SDK github上打开的一张票上回答了这个问题 - &gt; https://github.com/OfficeDev/Office-365-SDK-for-Android/issues/88
希望对某人有所帮助:)。
