Layout inflater with DialogFragment

Question

I'm trying to inflate my custom layout (a dialog fragment).

I have this in my function showDialog()

    val inflatedView = layoutInflater.inflate(R.layout.alerts_dialog_remi, null)

    mydialog = Dialog(this, R.style.DialogCustomTheme)
    mydialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
    mydialog.setContentView(R.layout.alerts_dialog_remi)
    mydialog.setOnShowListener {
        val text = inflatedView.findViewById<TextView>(R.id.alerte_title)
        val lp = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)
        text.setText("Text")}

        mydialog.create()

        txt = mydialog.findViewById(R.id.close_modal_alerte)
        txt.isEnabled = true
        txt.setOnClickListener{
            mydialog.cancel()
        }
        mydialog.show()
    }

But I don't see the "Text" string in my dialog fragment. I tried the put the inflatedView inside setOnShowListener, but it doesn't do anything either.

You don't need to inflate your view, because dialog.setContentView does just that for you.

What you need is to get the inflated view from inside your lambda.

Like this:

 mydialog.setOnShowListener {
    val text = it.view.findViewById<TextView>(R.id.alerte_title)
