Question

내가 작업하는 CursorLoader을 만들어 한 내 Contentprovider (제공자를 보려면 클릭)하지만 난

이

"방법 swapCursor (커서)를 위해 정의되지 않은 swapCursor 오류를 수신하고 유형 CursorAdapter "changeCursor에

변경된 SwapCursor 오류를 제거합니다.

새 오류가 로더 또는 공급자가 sqlite 데이터를 가져 오는 중입니다. logcat을 참조하십시오

어떤 도움을 주시면 대단히 감사하겠습니다.

SQLite는 DB는 :

어댑터에서 사용할 수하기 위해

String sqlDataStore = "create table if not exists " + 
     TABLE_NAME_INFOTABLE + " ("+ BaseColumns._ID + " integer primary key autoincrement," 

        + COLUMN_NAME_SITE + " text not null," 
        + COLUMN_NAME_ADDRESS + " text not null," 
        + COLUMN_NAME_USERNAME + " text not null,"

        + COLUMN_NAME_NOTES + " text not null);"; 

     db.execSQL(sqlDataStore); 
    }
