如何把spinner中的dropdown item存储到sqlite数据库？

public class Akshay extends Activity {

   public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.configuration);
    // Spinner For Selecting Room

    Spinner spinner_room = (Spinner) findViewById(R.id.spinner_for_Room_type_screen_2);

    ArrayAdapter<CharSequence> adapter_room = ArrayAdapter.createFromResource(this,
                        R.array.room_array,android.R.layout.simple_spinner_item);

    adapter_room.setDropDownViewResourc(android.R.layout.simple_spinner_dropdown_item);
    spinner_room.setAdapter(adapter_room);

    spinner_room.setOnItemSelectedListener(new Listener_Of_Selecting_Room_Spinner());
}

// Listener Implementation of Spinner For Selecting Room

public static class Listener_Of_Selecting_Room_Spinner implements OnItemSelectedListener 
{
    static String RoomType;

    public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) 
    {   
        // By using this you can get the position of item which you
        // have selected from the dropdown 

        RoomType = (parent.getItemAtPosition(pos)).toString();
    }

    public void onNothingSelected(AdapterView<?> parent) 
    {           
        // Do nothing.
    }
};

// Listener Implementation For Saving Number Of Board
private OnClickListener btnListener_Btn_Save_Room_Board = new OnClickListener() 
{
    public void onClick(View view) 
    {
        DBAdapter dbAdapter1 = new DBAdapter(view.getContext());

        String room;
        try {
            dbAdapter1.createDataBase();
            dbAdapter1.openDataBase();

            // Here i am using the object RoomType which i have got from 
            // the Listener of spinner

            room = Listener_Of_Selecting_Room_Spinner.RoomType;

            ContentValues initialValues1 = new ContentValues();

            initialValues1.put("RoomType", room);

            //Here i am storing it(RoomType) to the database

            dbAdapter1.InsertNumberOfBoardInDB("Configuration", null,initialValues1);   
        }
        catch (Exception e) {
        }
        finally {
            dbAdapter1.close();
        }
    }
};
}
