Get a date from a DatePickerDialog in Kotlin Android

The below snippet of code 'works' in the sense it updates the statusDateID correctly. the issue I am having is that although it sets the statusDateID correctly, the date will not persist, and when I update mh.entryDate it is always the current date.

How do I get the date outside of the dialog. so that I can update mh.entryDate with the chosen date, not the current date.

Thank you for your time.

fun changeDate(view: View) {

    var date: Calendar = Calendar.getInstance()
    var thisAYear = date.get(Calendar.YEAR).toInt()
    var thisAMonth = date.get(Calendar.MONTH).toInt()
    var thisADay = date.get(Calendar.DAY_OF_MONTH).toInt()

    val dpd = DatePickerDialog(this, DatePickerDialog.OnDateSetListener { view2, thisYear, thisMonth, thisDay ->
        // Display Selected date in textbox
        thisAMonth = thisMonth + 1
        thisADay = thisDay
        thisAYear = thisYear

        statusDateID.setText("Date: " + thisAMonth + "/" + thisDay + "/" + thisYear)
        val newDate:Calendar =Calendar.getInstance()
        newDate.set(thisYear, thisMonth, thisDay)

    }, thisAYear, thisAMonth, thisADay)
    dpd.show()

    mh.entryDate = date.timeInMillis
    println("DATE DATA: "+thisAYear+ " "+thisAMonth+" " + thisADay)
    println("DATE CHANGED MILLISECS = "+mh.entryDate)
}

mh.entryDate is defined as a global, and as a LONG. With the debugging println statements, both the DATE DATA and the DATE CHANGED MILLISECS show the current date.

You're instantiating the date object as a new instance from Calendar, but you are not updating it with the date from the picker. date is created, queried, but never updated.

Just set date inside DatePickerDialog.OnDateSetListener method with mh.entryDate = newDate.timeInMillis 

val dpd = DatePickerDialog(this, DatePickerDialog.OnDateSetListener { view2, thisYear, thisMonth, thisDay ->
    // Display Selected date in textbox
    thisAMonth = thisMonth + 1
    thisADay = thisDay
    thisAYear = thisYear

    statusDateID.setText("Date: " + thisAMonth + "/" + thisDay + "/" + thisYear)
    val newDate:Calendar =Calendar.getInstance()
    newDate.set(thisYear, thisMonth, thisDay)
    mh.entryDate = newDate.timeInMillis // setting new date
}, thisAYear, thisAMonth, thisADay)
dpd.show()
