title: Declare ImageView in kotlin Android Studio
body: <p>What I want is to do this (which is in Java):</p>
  <pre><code>public class MainActivity exteds AppCompatActivity{
      ImageView logo;
  
      @override
      protected void onCreate(Bundle savedInstanceState)
      {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
          logo = findViewById(R.id.logo);
      }
  </code></pre>
  <p>when taking it to Kotlin I get an error:</p>
  <p><img src="https://i.stack.imgur.com/BpM5m.png" alt="enter image description here" /></p>
  <p>Please could you tell me which of the options to keep so that the error does not appear?</p>
