DatePickerDialog 使用代码块

Calendar calendar = Calendar.getInstance();

                DatePickerDialog datePickerDialog = new DatePickerDialog(
                        context, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

                        //year + "-" + (monthOfYear+1) + "-" + dayOfMonth

                        birthdayTextView.setText(year + "-" + (monthOfYear+1) + "-" + dayOfMonth);
                    }
                }, calendar.get(Calendar.YEAR),
                        calendar.get(Calendar.MONTH),
                        calendar.get(Calendar.DAY_OF_MONTH));
                datePickerDialog.show();
