Ошибка исключения SQLite, используя CursorLoader & ContactContracts

Я пытаюсь заполнить ListView (это фрагмент) в действие, которое загружает контакты телефона Android. А так как я не знаком с запросами SQLite стиля, я, возможно, перепутался синтаксис, потому что я получил эту ошибку:Ошибка исключения SQLite, используя CursorLoader & ContactContracts

java.lang.RuntimeException: An error occurred while executing doInBackground() 
Caused by: android.database.sqlite.SQLiteException: near "display_name": syntax error (code 1): , while compiling: SELECT _id, photo_thumb_uri, display_name, has_phone_number FROM view_contacts_restricted WHERE ((1)) AND ((photo_thumb_uri=?display_name=?has_phone_number=?)) ORDER BY display_nameASC

два вопроса:

Ниже моя фрагмент кода и моего логарифма. Что-то не так? (Что вызывает ошибку?)
Я не использую компоновку xml-фрагмента (хотя я и пробовал раньше, поэтому код с комментариями все еще существует), потому что я читал, что CursorLoader создает свой собственный макет. Это правильное предположение?

проблема, как представляется, эта часть вашего запроса и ((photo_thumb_uri =? Display_name =? Has_phone_number =?)) вам нужно отделить его оператором OR/AND –

Хорошо, спасибо Ражену. Я просто не знаю, что с ними не так, это мои 3 константы в моем запросе. Я посмотрю их снова. Считаете ли вы, что я использую их в 'FROM',' PROJECTION', 'FILTER',' PROJECTION' и 'SELECTION_ARGS'? Мне было интересно, слишком ли много повторений. – Azurespot

Пространство требуется между ContactsContract.Contacts.DISPLAY_NAME и "ASC"

Изменить этот

return new CursorLoader(getActivity(), 
      contentUri, 
      PROJECTION, 
      FILTER, 
      SELECTION_ARGS, 
      ContactsContract.Contacts.DISPLAY_NAME + "ASC");

return new CursorLoader(getActivity(), 
      contentUri, 
      PROJECTION, 
      FILTER, 
      SELECTION_ARGS, 
      ContactsContract.Contacts.DISPLAY_NAME + " ASC");

Спасибо, kalyan, я добавил пробел, но все еще получаю ту же ошибку. – Azurespot

Конечно, я добавил его выше. – Azurespot
