Question

在Anko的警报构建器中使用positiveButton和negativeButton时，即使未调用dismiss()，它们似乎也会导致关闭对话框。有没有办法在点击按钮后保持对话框打开（如果有positiveButton / negativeButton以外的类型，那也很好）？

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

Answer 1

对于将来可能遇到此问题的任何人，您可以在Kotlin中完成此任务

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()
    }

Answer 2

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

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