title: Android TabLayout Scroll Selected tab to the left
body: <p>I would like to always left align <code>TabLayout.Tab</code> when they are selected. Currently, the selected tab gets aligned in the middle. How can I achieve this?</p>
  
  <p>Also, how to get relative position of tab that is visible? For ex, the tab that I selected is visible and is left most in the TabLayout. Relative position should be 0 for this tab.</p>
  
  <p>Thanks,</p>
