데이터베이스 생성시 여러 레코드 삽입

Question

sqlite 데이터베이스에 한 번에 여러 레코드를 삽입하려고합니다. DB를 채운 다음 해당 레코드를 사용하여 listview를 채 웁니다. 그래서 두 번째 두 번째 활동 즉, MenuActivity의 oncreate 메소드에서 삽입 쿼리를 실행하려고 생각했습니다. DB를 채울 것이라고 생각하고 필요한 데이터를 검색 할 수있게되었습니다. 하지만 그것은 logcat에 약간의 오류를주고 있습니다. 누구든지이 일을 도울 수 있습니까?

MenuActivity.java

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     //requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.activity_menu); 

     //setting db environment 
     dbhelper = new ToursOpenHelper(this); 
     sqldb = dbhelper.getWritableDatabase(); 
     sqldb.execSQL("INSERT INTO "+tourEntry.TABLE+ 
" SELECT "+tourEntry.TOURTYPE+" AS 'Tour_type' , "+tourEntry.TOURNAME+" AS 'Tour_name', "+tourEntry.NIGHTS+" AS 'Nights', "+tourEntry.DAYS+" AS 'Day', "+tourEntry.PIC+" AS 'Pic'"+ 
" UNION SELECT '1', '3', 'Delhi Tour', '1', '2', 'img/mini-vacation/lotus.png'"+ 
" UNION SELECT '2', '3', 'Taj Mahal Tour By Train (Same Day Return)', '1', '1', 'img/mini-vacations/taj-train.jpg"+ 
" UNION SELECT '3', '3', 'Taj Mahal Trip By Car (Same Day Return)', '1', '1', 'img/mini-vacations/'"+ 
" UNION SELECT '4', '3', 'Taj Mahal Trip', '1', '2', 'img/mini-vacations/noimg.png'"+ 
" UNION SELECT '5', '3', 'Pink City Tour (Same Day Return)', '1', '1', 'img/mini-vacations/noimg.png'");

내가 사용하지 않을는에서 onCreate 방법에 만 데이터베이스 방식과 다른 아무것도를 만들기 위해 사용되어야로 그렇게. 가장 좋은 방법은 databaseAdapter 또는 완전히 새로운 클래스의 모든 삽입 작업을 수행하고 응용 프로그램 사이클의 어느 곳에서나 onCreate 메서드를 호출 한 후에 호출하는 다른 메서드를 만드는 것입니다.
