title: Recyclerview scroll to a specific position
body: <p>I have a <code>recyclerview</code> of different categories. Each category has its own products. However, for getting products we have to call an API with respect to the category and load those products into the category item as a horizontal <code>recyclerview</code>. It all works well. </p>
  
  <p>I should only call the products API when the user scrolls to that particular category. When the user scrolls to a particular category I need to call the products list API and show inside the category item. </p>
  
  <p>My problem is I could not identify the currently visible item in the <code>recyclerview</code> and could not find the visible item when scrolling.</p>
