How to implement DatePickerDialog in Dialog Fragment?
Dialog class code:

public class MyDialog extends DialogFragment implements View.OnClickListener
{
    int idDialog;
    final String LOG = "myLogs";
    View rootView;
    String srezults="", str="";
    TextView incTextDate;
    EditText incEditMoney, incEditComent;
    Button incBtnAdd;
    String datestr="";
    Context context;
    private static final String TAG = "myLogs";
    int w, h; // ширина и высота экрана

    int myYear = 2015;
    int myMonth = 11;
    int myDay = 14;

    static MyDialog newInstance(int num, String srezults)
    {
        MyDialog f = new MyDialog();

        // Supply num input as an argument.
        Bundle args = new Bundle();
        args.putInt("id", num);

        args.putString("srezults", srezults);
        f.setArguments(args);
        return f;
    }

    public interface onMyDialigEventListener {
        public void someEvent(String s);
    }

    onMyDialigEventListener categoryEventListener;

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        //this.activity = activity;
        context=activity;
        setRetainInstance(true);

        try {
            categoryEventListener = (onMyDialigEventListener) activity;
        } catch (ClassCastException e) {
            throw new ClassCastException(activity.toString()
                    + " must implement onSomeEventListener");
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {

        // ставим прозрачный цвет
        getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

        // убираем title из окна
        getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        //getDialog().setTitle("Simple Dialog");

        idDialog = getArguments().getInt("id");

            incBtnAdd = (Button)rootView.findViewById(R.id.incBtnAdd);
            incBtnAdd.setOnClickListener(this);

            incTextDate.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v)

                            incTextDate.setText(myDay + "/" + myMonth + "/" + myYear);
                        }
                    };
                    DatePickerDialog tpd = new DatePickerDialog(context, myCallBack, myYear, myMonth, myDay);
