Вставка нескольких строк сразу в базу данных sqlite

Question

Я пытаюсь вставить несколько строк в базу данных sqlite. Я создал класс SqliteOpenHelper и создал базу данных и таблицу. Теперь мне нужно сделать, это вставить несколько строк в базу данных.

Скажем, у нас есть пять рядов, чтобы вставить сразу, что является лучшим и эффективным способом его достижения.

INSERT INTO `events` (`_id`, `event_name`, `start_date`, `end_date`, `event_city`, `event_state`, `event_pic`, `event_desc`, `wiki_url`, `event_cat`) VALUES 
(1, 'Purna Kumbh Fair 2013', '2013-01-27', '2013-03-10', 'Allahabad', 'Uttar Pradesh', 'img/kumbh.jpg', 'Kumbh Fair is a mass Hindu pilgrimage of faith in which Hindus gather at a sacred river for a bath in the river. It is held every third year at one of the four places by rotation: Haridwar, Prayag (Allahabad), Nasik and Ujjain.', 'http://en.wikipedia.org/wiki/Kumbh_Mela', 2), 
(2, 'Taj Mahotsav 2013', '2013-02-18', '2013-02-27', 'Agra', 'Uttar Pradesh', 'img/taj-mahotsav.jpg', 'aj Mahotsav is an annual 10 day (from 18 to 27 February) event at Shilpgram in Agra, India.

Попробуйте сделать отдельный класс для базы данных, как

public class databasehandler extends SQLiteOpenHelper{ 

private static final int DATABASE_VERSION = 5; 
     // Database Name 
     private static final String DATABASE_NAME = "atabase"; 

     // Contacts table name 
     private static final String TABLE_Name = "task"; 
     // Contacts Table Columns names 
     private static final String event_name= "event_name"; 
     private static final String start_date= "start_date"; 
     private static final String KEYID="id"; 
     private static final String end_date= "end_date"; 
     private static final String event_pic= "event_pic"; 
     private static final String event_desc= "event_desc"; 
     private static final String wiki_url= "wiki_url"; 
     private static final String event_cat= "event_cat"; 


public databasehandler(Context context){ 
       super(context, DATABASE_NAME, null, DATABASE_VERSION); 
      } 

@Override 
      public void onCreate(SQLiteDatabase db) { 
       // TODO Auto-generated method stub 
       String CREATETABLE = "CREATE TABLE " + TABLE+ "(" 
         + KEYID + " INTEGER PRIMARY KEY AUTOINCREMENT," + event_name+ " TEXT," 
         + start_date+ " TEXT," + end_date+" TEXT "+ ..... so on ")"; 
           db.execSQL(CREATE_TASK_TABLE); 
       db.execSQL(CREATETABLE); 

      } 



@Override 
      public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
       // Drop older table if existed 
       db.execSQL("DROP TABLE IF EXISTS " + TABLE); 
           // Create tables again 
       onCreate(db); 

      } 

void adddata(Classname Object) { 
       SQLiteDatabase db = this.getWritableDatabase(); 

       ContentValues values = new ContentValues(); 
       values.put(event_name, Object.getevent_name()); 
       values.put(start_date, Object.gestart_date()); 
       values.put(TASK_ID, Object.getTASK_ID()); 
             insert all values.... 

       // Inserting Row 
       db.insert(Table_tasknotification, null, values); 
       // Closing database connection 
      } 

} 

и теперь Classname.java

public class Classname { 
    //private variables name like 
       String event_name; 
       .... so on 

     // Empty constructor 
     public Classname(){ 

     } 
     // constructor 
     public Classname (String event_name, String start_date,String end_date.....){ 
      this.event_name= event_name; 
      this.start_date=start_date; 
      this.end_date=end_date; 
     } 


     public int getID(){ 
      return this._id; 
     } 

     // setting id 
     public void setID(int id){ 
      this._id = id; 
     } 
        and all the get and set methods.... 



} 

и в главном классе: -

databasehandler handler=new databasehandler (context); 
handler.adddata(new Classname(event_name, start_date,end_date....)); 

попробуйте это, он будет helo you :) , а также проверить эту ссылку http://www.androidhive.info/2011/11/android-sqlite-database-tutorial/
