这可能会对您有所帮助。你需要尝试这一点 -

我认为最好使用特定大小的缓冲区而不是全部加载成一个字符串然后使用它。 – 2015-11-09 10:40:35

您可以在联系人应用程序手动完成。但是没有这个意图。如果你想要你的应用程序有这样的出口，不幸的是你必须自己写或使用这里的代码。 vcardio

以下是如何解压到VCF文件，并通过意图分享，以期分享一个联系人的选项，如果你想：

@WorkerThread 
    @Nullable 
    public static Intent getContactShareIntent(@NonNull Context context, @Nullable String contactId, @NonNull String filePath) { 
     final ContentResolver contentResolver = context.getContentResolver(); 
     Cursor cursor = TextUtils.isEmpty(contactId) ? contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null) : 
       contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, Data.CONTACT_ID + "=?", new String[]{contactId}, null); 
     if (cursor == null || !cursor.moveToFirst()) 
      return null; 
     final File file = new File(filePath); 
     file.delete(); 
     do { 
      String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)); 
      Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey); 
      AssetFileDescriptor fd; 
      try { 
       fd = contentResolver.openAssetFileDescriptor(uri, "r"); 
       if (fd == null) 
        return null; 
       FileInputStream fis = fd.createInputStream(); 
       IOUtils.copy(fis, new FileOutputStream(filePath, false)); 
       cursor.moveToNext(); 
      } catch (Exception e1) { 
       e1.printStackTrace(); 
      } 
     } while (cursor.moveToNext()); 
     Intent intent = new Intent(Intent.ACTION_SEND); 
     intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); 
     intent.setType("*/*"); 
     return intent; 
    }

这已经改变您现在可以使用“人员”应用将您的联系人导出为VCF文件：在菜单中选择“导入/导出”，然后选择其中一个导出项目。你仍然需要将文件从你的手机中取出，但通过亚行（或者电子邮件）很容易。
