How to use spinner for showing date in sql lite in

I want to have 3 spinner in my app that are for date picking like this: Year – Month- Day For example, today is 2015-10-08 and spinners show this date automatically from system: year-spinner shows 2015 Month-spinner shows 10 Day-spinner shows 08 Although users can change them with dropping down and selecting other one. At last these data must be save in my sql-lite data base. I don't know how to them, please help me.thanks!

This is my code:

my app description is after AddVow is clicked, user add some data as number and date.number is taken by edit text and date is taken by spinner(as i describe above)

MyActivity.class:

public class MyActivity extends Activity   {

private ListView listView;
private AddVowAdapter adapter;
private DataBaseClass classDB;
private SQLiteDatabase sqlDB;

private ArrayList<String> vowId = new ArrayList<String>();  
private ArrayList<String> vow_number = new ArrayList<String>();
private ArrayList<String> vow_start = new ArrayList<String>(); 


private AlertDialog.Builder build;  // options for Edit/Delete


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    listView = (ListView) findViewById(R.id.ListView);
    classDB =new DataBaseClass(this);

    // edit and delete code  
     listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> adapterView, View view,final int i,final long l) {
            // creating dialog
            build = new AlertDialog.Builder(MyActivity.this);
            //Edit
            build.setNegativeButton("ویرایش کردن نذز",
                    new DialogInterface.OnClickListener() {

                        public void onClick(DialogInterface dialog,
                                            int which) {
                            Intent edit_intent = new Intent(getApplicationContext(), AddVowActivity.class);
                            edit_intent.putExtra("id", vowId.get(i));
                            edit_intent.putExtra("number", vow_number.get(i));
                            edit_intent.putExtra("startDate", vow_start.get(i));
                             startActivity(edit_intent);
                            dialog.cancel();
                        }
                    });
            AlertDialog alert = build.create();
            alert.show();

            return true;
        }
    });

Use like this,

public class SpinActivity extends Activity implements AdapterView.OnItemSelectedListener{

    private Spinner spYear;
    private Spinner spMonth;
    private Spinner spDate;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_spinner_date);

        spYear = (Spinner) findViewById(R.id.sp_year);
        spMonth = (Spinner) findViewById(R.id.sp_month);
        spDate = (Spinner) findViewById(R.id.sp_date);

        ArrayList<String> years=new ArrayList<>();
        int minYear=1980;
        for(int i=minYear; i<=2020; i++){
            years.add(String.valueOf(i));
        }
        ArrayAdapter<String> yearAdapter=new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, years);
        spYear.setAdapter(yearAdapter);


        ArrayList<String> months=new ArrayList<>();
        for(int i=1; i<=12; i++){
            months.add(String.format("%02d", i));
        }
        ArrayAdapter<String> monthAdapter=new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, months);
        spMonth.setAdapter(monthAdapter);

        ArrayList<String> dates=new ArrayList<>();
        for(int i=1; i<=31; i++){
            dates.add(String.format("%02d", i));
        }
        ArrayAdapter<String> dateAdapter=new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, dates);
        spDate.setAdapter(dateAdapter);

        Calendar calendar=Calendar.getInstance();
        spDate.setSelection(calendar.get(Calendar.DATE)-1);
        spMonth.setSelection(calendar.get(Calendar.MONTH));
        spYear.setSelection(calendar.get(Calendar.YEAR)-minYear);

        spDate.setOnItemSelectedListener(this);
        spMonth.setOnItemSelectedListener(this);
        spYear.setOnItemSelectedListener(this);
    }

    @Override

                break;
            case R.id.sp_month:// change accordingly dateadapter in based on month and year.
                break;
            case R.id.sp_year:// change accordingly dateadapter in based on month and year.
                break;
        }

        String date=spDate.getSelectedItem().toString();
        String month=spMonth.getSelectedItem().toString();
        String year=spYear.getSelectedItem().toString();

       Log.d("SpinActivity", "onItemSelected :"+date+"  "+month+"  "+year);

        // store your date format in your database here.
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
}

layout (activity_spinner_date):

<?xml version="1.0" encoding="utf-8"?>
