title: Android kotlin - Unresolved reference for setImageBitmap in fragment
body: <p>I just try to set a Bitmap inside an ImageView in fragment:</p>
  
  <pre><code>imageLeft.setImageBitmap(duelbildBitmap)
  </code></pre>
  
  <p>and get <code>Unresolved reference</code> for <code>setImageBitmap</code></p>
  
  <p>Why? It works in activity</p>
  
  <p>Thanks in advance</p>
