Can't select date with datepickerdialog

Question

I have some trouble using the DataPickerDialog in kotlin...
This is how I would like it to work:
First, when the user selects a date, it must update a textview and the dialog must close
But for now, when the user selects a date, nothing happens (apart from the update in the dialog itself).
Here is my code :

@AndroidEntryPoint
class AppointmentListFragment : Fragment() {

    private var _binding: FragmentAppointmentListBinding? = null
    private val binding: FragmentAppointmentListBinding
        get() = _binding!!

    private val viewModel: AppointmentMainViewModel by viewModels()
    private val today = Calendar.getInstance()
    private val day = today.get(Calendar.DAY_OF_MONTH)
    private val month = today.get(Calendar.MONTH) + 1
    private val year = today.get(Calendar.YEAR)

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {
        _binding = FragmentAppointmentListBinding.inflate(inflater)
        setDateText(
            getString(
                R.string.date_placeholder,
                String.format("%02d", day),
                String.format("%02d", month),
                year
            )
        )

        binding.appointmentDateButton.setOnClickListener {
            val dpd = DatePickerDialog(
                it.context,
                { datePicker, y, m, d ->
                    datePicker.minDate = System.currentTimeMillis()
                    setDateText(
                        getString(
                            R.string.date_placeholder,
                            String.format("%02d", d),
                            String.format("%02d", m),
                            y
                        )
                    )
                },
                year,
                month,
                day
            )
            dpd.show()
        }
        return binding.root
    }

    private fun setDateText(date: String) {
        binding.appointmentDateButton.text = date
    }

What am I missing ?
Thanks in advance

Answer 1

What do you get in setDateText? I copied almost all code and launched. Then got y, m, d inside onDateSet callback. So, a string

getString(
    R.string.date_placeholder,
    String.format("%02d", d),
    String.format("%02d", m),
    y
)

should be right (but I don't know what you have put in date_placeholder).

So, this string is passed to setDateText and is written in appointmentDateButton (19 05 2022). I don't know, what happened.

By the way, initial month is incremented by 1. It's a mistake (you open the picker on 19th' June).
