在Android應用程序中循環填充SQLite表格

Question

我必須用50個美國國家及其各自的首字母來填充一個SQLite表格。我是一個新手，所以我一直在下面的方式來完成它，但我知道必須有一個更簡單的方法：

public void populateDB() 
    { 
    SQLiteDatabase db = openOrCreateDatabase("mydb.db",SQLiteDatabase.CREATE_IF_NECESSARY, null); 
    db.setLockingEnabled(true); 
    db.setVersion(1); 

    final String sqlcmd="create table IF NOT EXISTS gameinfo(_id integer primary key" + 
         "autoincrement state text not null, autoincrement capital text not null);"; 
    db.execSQL(sqlcmd); 
    ContentValues cv = new ContentValues(); 
    cv.put("state", "Alabama"); 
    cv.put("captial", "Montgomery"); 
    cv.put("state", "Alaska");

你應該創建一個表助手來創建和填充數據庫表

public class DictionaryOpenHelper extends SQLiteOpenHelper { 

private static final int DATABASE_VERSION = 2; 
private static final String DICTIONARY_TABLE_NAME = "dictionary"; 
private static final String DICTIONARY_TABLE_CREATE = 
      "CREATE TABLE " + DICTIONARY_TABLE_NAME + " (" + 
      KEY_WORD + " TEXT, " + 
      KEY_DEFINITION + " TEXT);"; 

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

@Override 
public void onCreate(SQLiteDatabase db) { 
    db.execSQL(DICTIONARY_TABLE_CREATE); 
    // db = getWritableDatabase(); 
    // put your data population code here 
} 

}
