            it.dialogBuilder()
        }
        return builder.create()

    fun AlertDialog.Builder.negativeButton(text: String = "Dismiss", handleClick: (dialogInterface: DialogInterface) -> Unit = {}) {
        this.setPositiveButton(text) { dialogInterface, which -> handleClick(dialogInterface) }
    }

}

//Usage 
PromptUtils.alertDialog(this, R.style.AlertDialog_AppCompat_Light) {
            setTitle("Permission")
            setMessage("Storeage read and write permission?")
            positiveButton(){
                //do positive actions
                it.dismiss()
            }
            negativeButton(){
                //do negative actions
                it.dismiss()
            }

How can we get textview or spinner value in

alert {
setTitle("Confirm")
setMessage("Are you sure you want to delete this item?")
positiveButton { textview or spinner value here }
negativeButton { //do something }
}
