title: Add Icons to SlidingTabLayout instead of Text
body: <p>I'm implementing a SlidingTabLayout in my android application. What my query is that I'd like to implement icons in my Sliding Tabs instead of texts for navigation. I searched heavily on the internet for any such tutorial or sample but found none. I also searched a previous question on stackoverflow: <a href="https://stackoverflow.com/questions/23420293/android-slidingtablayout-with-icons">Over Here - SlidingTabLayout with Icons</a>. It was slightly informative but didn't really help me out.</p>
  
  <p>To be clear. I require my tabs to consist of <strong><em>icons only</em></strong>. No text.</p>
  
  <p>As I am new to this whole setup, I'd appreciate if you'd post proper code with an explanation. Thank you for your time and effort!</p>
  
  <p><strong>P.S.</strong> <em>I also heard about the pagerslidingtabstrip by Andreaz Stuetz and wondered if that would be more suitable for the type of thing I'm going for...</em></p>
  
  <p><strong>Also:</strong> Here is what I would like my sliding tabs to look like. Check out the top of this image.</p>
  
  <p><strong><em>EDIT : NOW THAT LOLLIPOP (WITH MATERIAL DESIGN) HAS COME OUT. I HAVE SEEN A LOT OF APPS USING A NEW "ONLY ICON" <code>SLIDING-TAB-LAYOUT</code> BELOW THEIR TOOLBAR (ANDROID 5.0 ACTION-BAR). IS THEIR ANY NEW WAY TO IMPLEMENT THIS?? THANKS ONCE AGAIN!</em></strong></p>
