title: Determine if the NavigationDrawer is opening or closing
body: <p>Is there any way for me to determine whether the navigation drawer is opening or closing? I have read about <code>isDrawerOpen()</code> and <code>isDrawerVisible()</code> methods, but they only return true if the navigation drawer is opened or is visible respectively. </p>
  
  <p>I also read about <code>onDrawerSlide(View drawerView, float slideOffset)</code> method which gets called when the drawer is moving. The <code>slideOffset</code> is the floating value between 0 and 1 telling which position the drawer is at now. But even that gets called when the drawer is opening <strong>and</strong> closing.</p>
  
  <p>What I need to do is, to do something only when the drawer is opening but not when closing, something tells me that I have to use <code>onDrawerSlide(View drawerView, float slideOffset)</code> method, but I just can't figure out how to check if it is opening and is not closing.</p>
  
  <p>Thank you</p>
