如何从Android中的联系人中的联系人ID获取只读帐户名称

Question

我将帐户名称从列表传递给此方法。现在我想知道哪些这些帐户名称只在联系人表中读取，所以我只迭代光标一次从原始光标获取联系人ID。获取contact_id后，我使用电话游标来检查给定的ID是否只读，但我无法做到。请有以下

private void displayAllContactsByType(String accountName) { 

    Cursor rawCursor,phones = null; 

    rawCursor = cResolver.query(
      ContactsContract.RawContacts.CONTENT_URI, 
      new String[]{ContactsContract.RawContacts.CONTACT_ID}, 
      ContactsContract.RawContacts.ACCOUNT_NAME + "= ?", 
      new String[]{accountName}, 
      null); 


    int contactIdColumn = rawCursor.getColumnIndex(ContactsContract.RawContacts.CONTACT_ID); 
    int rawCursorCount = rawCursor.getCount(); 


    Utils.Log("Account Name", accountName); 

    Utils.Log("Raw Size", " " + rawCursorCount); 
    rawCursor.moveToFirst(); 
    Long contactId = rawCursor.getLong(contactIdColumn); 


    phones = cResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
      null, 
      ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND "+ContactsContract.RawContacts.ACCOUNT_NAME + "= ?", 
      new String[]{String.valueOf(contactId),accountName}, 
      null); 

    phones.moveToFirst(); 




    String isReadOnly= phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.IS_READ_ONLY)); 
    Utils.Log("Raw Size", isReadOnly); 


}

你不必去了一个帐户的联系人来检查看看，你可以简单地在设备上的SyncAdapters迭代，并检查它们的属性：

final SyncAdapterType[] syncs = ContentResolver.getSyncAdapterTypes(); 
for (SyncAdapterType sync : syncs) { 
    Log.d(TAG, "found SyncAdapter: " + sync.accountType); 
    if (ContactsContract.AUTHORITY.equals(sync.authority)) { 
     Log.d(TAG, "SyncAdapter supports contacts: " + sync.accountType); 
     boolean readOnly = !sync.supportsUploading(); 
     Log.d(TAG, "SyncAdapter read-only mode: " + readOnly); 
     if (readOnly) { 
      // we'll now get a list of all accounts under that accountType: 
      Account[] accounts = AccountManager.get(this).getAccountsByType(sync.accountType); 
      for (Account account : accounts) { 
       Log.d(TAG, account.type + "/" + account.name); 
      } 
     } 
    } 
} 

希望这可以帮助。
