title: Scroll not working properly for RecyclerView inside CoordinatorLayout
body: <p>Actually I am having 2 Problems</p>
  
  <p>1st. Scroll is not working properly, sometimes when we scroll a very small distance in a particular direction and leave the touch, it scrolls very fast till the end of that particular direction i.e., upside or down</p>
  
  <p>2nd. I want the title of the custom Toolbar to be shown only when its collapsed and when its expanded the title should be hidden</p>
  
  <p>Here's the XML Code</p>
  
  <pre><code>&lt;android.support.design.widget.CoordinatorLayout
