Anko: Alerts cannot be non cancelable

[SalomonBrys]

val pwAlert = alert {
    titleResource = R.string.my_message
    messageResource = R.string.my_message
    okButton {}
    isCancelable = false // This does not exists
}

There is currently no way to create an alert with the alert function and set the dialog to be non cancelable.
I am "forced" to revert to java style creation when I need a non cancelable dialog.

BTW, it would also be great if there was a way to access the AlertDialog.Builder.

A much needed feature

[doitlite]

Before the new feature add to the library, you can try this:

val pwAlert = activity.alert(Appcompat) {
    titleResource = R.string.my_message
    messageResource = R.string.my_message
    okButton {}
}.build()
pwAlert.setCancelable(false)
pwAlert.setCanceledOnTouchOutside(false)
pwAlert.show()

@doitlite What Appcompat here? please explain more about it

UPDATE:
// Appcompat-v7 (only Anko Commons)
compile "org.jetbrains.anko:anko-appcompat-v7-commons:$anko_version"
Use this for Appcompat (alert.build() returns android.support.v7.app AlertDialog)

In version 0.9 I was able to call cancellable(false). It was removed from builder in 0.10 I wonder if there was a reason for that or was it forgotten during refactoring. It should be easy to restore if there is no reason behind it.

Hi , You can use after ".show()" .setCancelable(false)
for example ->
alert("Body") {
title = "Title"
positiveButton("ok") {
}
}.show().setCancelable(false)

doitlite is correct:

val pwAlert = activity.alert(Appcompat) {
    titleResource = R.string.my_message
    messageResource = R.string.my_message
    okButton {}
}.build().apply {
    setCancelable(false)
    setCanceledOnTouchOutside(false)
}.show()

I want to save dialog after screen rotation. but @doitlite and @Zhuinden don`t helps.
I hope the best way is to use ViewModel.

    val errorObservable: LiveData<SignInResult>

``` kotlin
observe(errorObservable, ::handleError)

``` kotlin
    private fun handleError(error: Any?) {
        if (error == null) {
            return
        }

        activity.alert(Appcompat) {
            titleResource = R.string.title
            messageResource = R.string.message
            okButton { mSignInViewModel.onErrorClosed() }
        }.build().apply {
            setCancelable(false)
            setCanceledOnTouchOutside(false)
        }.show()
    }
