title: Android Toolbar collapseMode issue
body: <p>I have an Issue making " toolbar with Title text " Not to Collapse while scrolling upwards in CollapsingToolbarLayout.</p>
  
  <p>I have tried a few tweaks, by using <strong>app:layout_collapseMode="none"</strong> as attribute in my android.support.v7.widget.Toolbar but its not working. Maybe there is a problem with my layout.</p>
  
  <p><strong>Below is what i am trying to achieve.</strong></p>
