title: Retrieve view in dialog
body: <p>I'm trying to manipulate views inside a dialog, but the only way I can retrieve the views is in the Java old fashioned way, like this:</p>
  
  <pre><code> class MyDialog: DialogFragment() {
          override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
              val alert = AlertDialog.Builder(context!!)
              val inflater = LayoutInflater.from(activity)
              val view = inflater?.inflate(R.layout.pg_dialog, null)
              with(alert) {
                  setView(view)
                  setNeutralButton(R.string.scambio_back, DialogInterface.OnClickListener({ _: DialogInterface, _: Int -&gt; dialog.dismiss() }))
              }
              view?.findViewById&lt;TextView&gt;(R.id.dialog_name)?.text = person.name
              view?.findViewById&lt;TextView&gt;(R.id.dialog_surname)?.text = person.surname
  
              return alert.create()
          }
      }
  </code></pre>
  
  <p>Do you know any way to retrieve inner views in Kotlin, avoiding findViewById?</p>
