DatePicker and DatePickerDialog are often used when requesting user to select date instead of typing in
Show DatePickerDialog in fragment
This will display a DatePickerDialog for user to choose date then output the result to textview.
val c = Calendar.getInstance()
val dpd = DatePickerDialog(activity!!, DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->
val dateString = "$year-${String.format("%02d", monthOfYear+1)}-${String.format("%02d", dayOfMonth)}"
textview.setText(dateString)
}, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH))
dpd.show()
