在skydrive SDK中獲取文件ID Android

Question

我正在製作可從skydrive下載文件的應用程序。我的應用程序使用skydrive SDK。我發現了一段代碼，可以從SkyDrive的文件下載到Android設備如下：

final LiveDownloadOperation operation = mClient.downloadAsync(fileId + "/content", file, new LiveDownloadOperationListener() { 
         @Override 
         public void onDownloadProgress(int totalBytes, int bytesRemaining, LiveDownloadOperation operation) { 
          int percentCompleted = computePrecentCompleted(totalBytes, bytesRemaining); 

          progressDialog.setProgress(percentCompleted); 
         } 

         @Override 
         public void onDownloadFailed(LiveOperationException exception, LiveDownloadOperation operation) { 
          progressDialog.dismiss(); 
          showToast(exception.getMessage()); 
         } 

         @Override 
         public void onDownloadCompleted(LiveDownloadOperation operation) { 
          progressDialog.dismiss(); 
          showToast("File downloaded."); 
         } 
        }); 

但我不知道從哪裏得到FILEID從SkyDrive中，使這個代碼工作。這是真棒，如果有一些例子

我找到解決方案爲我自己。只需獲取所有文件的列表，與查找文件進行比較，然後獲取它的ID。這裏是我的代碼：

public List<DFile> getFileIdFromName(String fileName) { 
    DFile res = null; 
    // List<DFile> dolphinListFile = getListFile(DIR_HOME); 
    // for (DFile dolphin : dolphinListFile) { 
    // if (dolphin.getFileName().compareTo(fileName) == 0) 
    // res = dolphin; 
    // } 
    boolean canGetId = true; 
    if (!isLoggedIn()) { 
     OnGetIdFromFileNameChecked(null, "Not logged in or check session false"); 
     canGetId = false; 
    } 
    if (canGetId) { 
     mFileList = new ArrayList<DFile>(); 
     final String mFileName = fileName; 
     mClient.getAsync(DIR_HOME + "/files", new LiveOperationListener() { 
      @Override 
      public void onComplete(LiveOperation operation) { 

       JSONObject result = operation.getResult(); 
       if (result.has(JsonKeys.ERROR)) { 
        JSONObject error = result.optJSONObject(JsonKeys.ERROR); 
        String message = error.optString(JsonKeys.MESSAGE); 
        String code = error.optString(JsonKeys.CODE); 
        Log.d("Dolphin download err", code + ": " + message); 
        return; 
       } 
       JSONArray data = result.optJSONArray(JsonKeys.DATA); 

       for (int i = 0; i < data.length(); i++) { 
        SkyDriveObject skyDriveObj = SkyDriveObject.create(data.optJSONObject(i)); 

        skyDriveObj.accept(new Visitor() { 
         @Override 
         public void visit(SkyDriveAlbum album) { 
          mDFile = new DFile(album.getId(), "N/A", album.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_ALBUM); 

         } 

         @Override 
         public void visit(SkyDrivePhoto photo) { 
          mDFile = new DFile(photo.getId(), "N/A", photo.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_PHOTO); 
         } 

         @Override 
         public void visit(SkyDriveFolder folder) { 
          mDFile = new DFile(folder.getId(), "N/A", folder.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_FOLDER); 
         } 

         @Override 
         public void visit(SkyDriveFile file) { 
          mDFile = new DFile(file.getId(), "N/A", file.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_FILE); 
         } 

         @Override 
         public void visit(SkyDriveVideo video) { 
          mDFile = new DFile(video.getId(), "N/A", video.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_VIDEO); 
         } 

         @Override 
         public void visit(SkyDriveAudio audio) { 
          mDFile = new DFile(audio.getId(), "N/A", audio.getName(), DFile.FILEHOST_SKYDRIVE, DFile.FILETYPE_AUDIO); 
         } 
        }); 
        if (mDFile.getFileName().compareTo(mFileName) == 0) { 
         mFileList.add(mDFile); 
        } 
       } 
       OnGetIdFromFileNameChecked(mFileList, "Complete"); 
      } 

      @Override 
      public void onError(LiveOperationException exception, LiveOperation operation) { 

       Log.d("Dolphin download err", exception.getMessage()); 
       OnGetListChecked(null, exception.getMessage()); 
      } 
     }); 
    } 
    return mFileList; 
}
