title: TextView on a map fragment does not follow its movement on dragging
body: <p>I am positioning a <code>TextView</code> on a Google Maps fragment like this:</p>
  <pre><code>private fun putTextView() {
      val layout : FrameLayout = findViewById(R.id.frameLayout)
      val textView : TextView = TextView(this)
      textView.textSize = 14F
      textView.text = &quot; some text &quot;
      textView.setTextColor(Color.BLACK)
      textView.setPaddingRelative(100,100,0,0)
      layout.addView(textView)
  }
  </code></pre>
  <p>It does appear where I want to it to appear, yet when I drag on the map, the <code>TextView</code> doesn't follow the movement but rather stays in the same place on the screen. How can I make it follow the movement of the map as I drag?</p>
