title: Get child from field via reflection
body: <p>So i have a class like this</p>
  <pre><code>class Fragment{
     private val binding: MyFragmentBinding
  }
  </code></pre>
  <p><code>MyFragmentBinding</code> has a private field &quot;webView&quot;, which I want to access.</p>
  <p>First step:</p>
  <pre><code>val firstField = fragment.javaClass.getDeclaredField(&quot;binding&quot;)
  </code></pre>
  <p>This works and I got a field with my binding class. But in this class I want to access the field with the name &quot;webView&quot;.
  How can I do this?</p>
