Kotlin / Anko prevent button from closing Alert Dialog

Question

When using positiveButton and negativeButton in Anko's alert builder, it seems both of them result in closing the dialog, even if dismiss() is not called. Is there any way to keep the dialog open after clicking a button (if there are types other than positiveButton/negativeButton, that's fine too)?

alert {
    title = "Add Board"
    customView {
        ....
    }
    positiveButton("OK") { doSomeFunction() }
    negativeButton("Close"){}
}.show()

I suppose that's the default behavior of Android's AlertDialog. — Bob, Aug 15 '17 at 15:28
@Bob ah, didn't realize that. I'll look and see if there are ways to override — Parker, Aug 15 '17 at 15:29

Thanks @Bob, overriding `onClickListener` after creating the dialog does the trick — Parker, Aug 15 '17 at 15:35

For anyone that may have this issue in the future, this is how you can accomplish this in Kotlin

val myAlert = alert {
    title = "Add Board"
    customView {
        ....
    }
    positiveButton("OK") { /*Keep blank, we'll override it later*/}
    negativeButton("Close"){}
    }.show()

//You can use BUTTON_NEGATIVE and BUTTON_NEUTRAL for other buttons
(myAlert as AlertDialog).getButton(AlertDialog.BUTTON_POSITIVE)
    .setOnclickListener{
        doSomeFunction()
    }

alert {
  title = "Add Board"
  customView {
    ....
  }
  positiveButton("OK") { /*Keep blank, we'll override it later*/}
  negativeButton("Close"){}

  isCancelable = false // Disable close here
}.show()

this will no prevent the alert from being closed with the buttons – Jose Luis Berrocal Oct 09 '19 at 00:30
