[Android] DatePicker, TimePicker

month는 0부터 시작하므로 +1을 해준 것.

class MainActivity : AppCompatActivity() {

    var cal = Calendar.getInstance()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        btn_datepicker.setOnClickListener{
            showDatePicker();
        }

        btn_timepicker.setOnClickListener{
            showTimePicker();
        }
    }

    fun showDatePicker(){
        DatePickerDialog(this, DatePickerDialog.OnDateSetListener{datePicker, year, month, day ->
            println(year)
            println(month + 1)
            println(day)
        }, cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DATE)).show();
    }

    fun showTimePicker(){
        TimePickerDialog(this, TimePickerDialog.OnTimeSetListener{timePicker, hour, minute ->
            println(hour)
            println(minute)
        }, cal.get(Calendar.HOUR), cal.get(Calendar.MINUTE), true).show()
    }
}
