Listener for OK button to easily get selected month and year?

[anta40]

I'm studying this example:

 builder.setActivatedMonth(Calendar.JULY)
                        .setMinYear(1990)
                        .setActivatedYear(2017)
                        .setMaxYear(2030)
                        .setMinMonth(Calendar.FEBRUARY)
                        .setTitle("Select trading month")
                        .setMonthRange(Calendar.FEBRUARY, Calendar.NOVEMBER)
                        // .setMaxMonth(Calendar.OCTOBER)
                        // .setYearRange(1890, 1890)
                        // .setMonthAndYearRange(Calendar.FEBRUARY, Calendar.OCTOBER, 1890, 1890)
                        //.showMonthOnly()
                        // .showYearOnly()
                        .setOnMonthChangedListener(new MonthPickerDialog.OnMonthChangedListener() {
                            @Override
                            public void onMonthChanged(int selectedMonth) {
                                Log.d(TAG, "Selected month : " + selectedMonth);
                                // Toast.makeText(MainActivity.this, " Selected month : " + selectedMonth, Toast.LENGTH_SHORT).show();
                            }
                        })
                        .setOnYearChangedListener(new MonthPickerDialog.OnYearChangedListener() {
                            @Override
                            public void onYearChanged(int selectedYear) {
                                Log.d(TAG, "Selected year : " + selectedYear);
                                // Toast.makeText(MainActivity.this, " Selected year : " + selectedYear, Toast.LENGTH_SHORT).show();
                            }
                        })
                        .build()
                        .show();

To check selected month/year, you use separate listeners (setOnMonthChangedListener and setOnYearChangedListener). What I want is after clicking "OK" on the picker, selected month/date can be automatically displayed. I don't see something like onClose or onDismiss, so my workaround is storing both month and year as global variables.
