title: How to callback a view created with an ID in Kotlin
body: <p>My current scripts are</p>
  <pre><code>fun addRow(text: String, rowNum: Int){
      val textViewNm: TextView = TextView(this.context)
      textViewNm.text = text
      textViewNm.gravity = Gravity.CENTER
      textViewNm.id = rowNum
      textBox.addView(textViewNm)
  }
  </code></pre>
  <p>I'd like to callback and control textViews made by &quot;addRow&quot; function.</p>
  <p>However I don't know how to call them back with ID (textViewNm.id = rowNum).</p>
  <p>nothing showed when I tried</p>
  <pre><code>textViewNm.1 ,2 ,3 // which was rowNum
  </code></pre>
