  <p>The problem is that I don't see my buttons from item xml. They become invisible when I fill RV with some data. I checked everything and can't understand how to fix this problem. I'm pretty sure that problem is with xml but I don't understand where it is. I used Layout inspector and I see that my buttons below RV in RV item, but I can't scroll and see them. Maybe I did any mistakes in xml? I thought that maybe problem is with fixed RV size or nested scrolling and added this code:</p>
  <pre><code>!answersList.hasFixedSize()
  answersList.isNestedScrollingEnabled = false
  </code></pre>
