android - 阅读所有联系人(包括从 facebook 等导入的)

Question

根据这个示例:http://developer.android.com/resources/samples/ContactManager/index.html我写了一个简单的函数来获取所有联系人:

 Uri uri = ContactsContract.Contacts.CONTENT_URI;
    String[] projection = new String[] {
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME
    };
    String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" +
            (mShowInvisible ? "0" : "1") + "'";
    String[] selectionArgs = null;
    String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

它运行良好，但不会返回使用 Facebook 应用程序导入的联系人(但它们在联系人应用程序中可见)。知道如何像在“联系人”应用程序中那样读取所有联系人吗？

谢谢

我认为您需要查看 RawContacts 才能找到该信息。

Android Contacts 是这样的文档说:

A row in the RawContacts table represents the set of Data and other information describing a person and associated with a single contacts source. For example, a row might define the data associated with a person's Google or Exchange account or Facebook friend. For more information, see ContactsContract.RawContacts.

RawContacts文档说:

The best way to read a raw contact along with all the data associated with it is by using the ContactsContract.RawContacts.Entity directory. If the raw contact has data rows, the Entity cursor will contain a row for each data row. If the raw contact has no data rows, the cursor will still contain one row with the raw contact-level information.

那里还有一些示例代码:

 Uri rawContactUri = 
   ContentUris.withAppendedId(RawContacts.CONTENT_URI, rawContactId);

 Uri entityUri = 
   Uri.withAppendedPath(rawContactUri, Entity.CONTENT_DIRECTORY);

 Cursor c = 
   getContentResolver().query(entityUri,
                              new String[]{RawContacts.SOURCE_ID, 
                                           Entity.DATA_ID, 
                                           Entity.MIMETYPE, 
                                           Entity.DATA1},
                              null, 
                              null, 
                              null);
 try 
 {
     while (c.moveToNext()) 
     {
         String sourceId = c.getString(0);

         if (!c.isNull(1)) 
         {
             String mimeType = c.getString(2);
             String data = c.getString(3);
             ...
         }
     }
 } 
 finally 
 {
     c.close();
 }
