how to bulk insert in sqlite in android

Question

I am using SQLiteOpenHelper for data insertion. I need to insert 2500 id and 2500 names, So it takes too much time. Please any one help me how to reduce the insertion tim

Answer 1

Use a transaction to insert all the rows -- NOT one row per transaction.

SQLiteDatabase db = ...
db.beginTransaction();
try {
    // do ALL your inserts here
    db.setTransactionSuccessful()
} finally {
    db.endTransaction();
}

EDIT

public void add_cities(List list) {
    SQLiteDatabase db = this.getWritableDatabase();
    db.beginTransaction();
    try {
        ContentValues values = new ContentValues();
        for (Cities city : list) {
            values.put(CityId, city.getCityid());
            values.put(CityName, city.getCityName());
            db.insert(TABLE_CITY, null, values);
        }
        db.setTransactionSuccessful();
    } finally {
        db.endTransaction();
    }
}

ALL inserts, ONE transaction.
