title: ViewPager2 default position
body: <p>I'm creating a slideshow with ViewPager2. For example, the slideshow has 3 items and I want to show the second item when the activity opens. I use <code>setCurrentItem(int item, boolean smoothScroll)</code> method but it doesn't work and nothing happens. How can I achieve it?</p>
  
  <pre><code>viewPager.adapter = adapter
  viewPager.setCurrentItem(1, true)
  </code></pre>
