Is there any example, how to inject an anko generated view/layout into a layout inflated from XML?
I have a placeholder (FrameLayout) in my XML layout and I want to populate it with an unknown number of `TextView`s, programmatically, at runtime.
I tried something like:
placeholder.addView(xxx), where xxx is a VerticalLayout created using anko,
but I am getting the Exception:
java.lang.IllegalStateException: The specified child already has a parent

I create the VerticalLayout with this function:

fun createTextViews() : View {
        return verticalLayout {
            textView {
                text = "TextView 1"
            }

            textView {
                text = "TextView 2"
            }
        }

    }

You mean, the problem is that I am creating the views in a function and not in-place?

maybe

I tried this:
placeholder.addView( this.linearLayout { textView("Text 1") })
and I am getting the same Exception.

and if you try like this:

[Roxana Nistor]

override fun createView(ui: AnkoContext<MainActivity>): View = with(ui) {
return relativeLayout {
val emptyView = textView(“Say something outrageous.“) {
textSize = 16f
typeface = Typeface.MONOSPACE
}.lparams {
centerInParent()
}

This is (almost) correct! Here is my version:

[nickk]

fun createView(ui: AnkoContext<Context>): View = with(ui) {
        return relativeLayout {
            val emptyView = textView("Say something outrageous.") {
                textSize = 16f
                typeface = Typeface.MONOSPACE
            }.lparams {
                centerInParent()
            }
        }
    }

and it’s working?

[nickk]

Yes

[Roxana Nistor]

good

Thanks!

So, I have to explicitly use an AnkoContext, I guess
