How to use DatePickerDialog in Kotlin?

Question

In Java an DatePickerDialog can be use such as:

final Calendar c = Calendar.getInstance(); int year = c.get(Calendar.YEAR); int month = c.get(Calendar.MONTH); int day = c.get(Calendar.DAY_OF_MONTH);   DatePickerDialog dpd = new DatePickerDialog(getActivity(),new DatePickerDialog.OnDateSetListener() {    @Override    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)   {       // Display Selected date in textbox       lblDate.setText(""+ dayOfMonth+" "+MONTHS[monthOfYear] + ", " + year);   } }, year, month,day); dpd.show(); 

How does Kotlin's DatePickerDialog use look like?

Answer 1

It would look something like this:

val c = Calendar.getInstance() val year = c.get(Calendar.YEAR) val month = c.get(Calendar.MONTH) val day = c.get(Calendar.DAY_OF_MONTH)   val dpd = DatePickerDialog(activity, DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->      // Display Selected date in textbox     lblDate.setText("" + dayOfMonth + " " + MONTHS[monthOfYear] + ", " + year)  }, year, month, day)  dpd.show() 

this was done by simply copying and pasting the code into a kotlin file in android studio. I would strongly recommend using it.

class MainActivity : AppCompatActivity() {      override fun onCreate(savedInstanceState: Bundle?) {         super.onCreate(savedInstanceState)         setContentView(R.layout.activity_main)          val textView: TextView  = findViewById(R.id.textView_date)         textView.text = SimpleDateFormat("dd.MM.yyyy").format(System.currentTimeMillis())          var cal = Calendar.getInstance()          val dateSetListener = DatePickerDialog.OnDateSetListener { view, year, monthOfYear, dayOfMonth ->             cal.set(Calendar.YEAR, year)             cal.set(Calendar.MONTH, monthOfYear)             cal.set(Calendar.DAY_OF_MONTH, dayOfMonth)              val myFormat = "dd.MM.yyyy" // mention the format you need             val sdf = SimpleDateFormat(myFormat, Locale.US)             textView.text = sdf.format(cal.time)          }          textView.setOnClickListener {             DatePickerDialog(this@MainActivity, dateSetListener,                     cal.get(Calendar.YEAR),                     cal.get(Calendar.MONTH),                     cal.get(Calendar.DAY_OF_MONTH)).show()         }     } }
