title: Cannot change active text color on TabLayout
body: <p>I am trying to style tabs in an android.support.design.widget.TabLayout  I can not get the selected tab color to change, it is always set to the textColorPrimary in my app theme, but I need them to be different colors.</p>
  
  <p>I have tried setting values in styles.xml that applies to TabLayout, but I read you can not change active tab text color this way, though I can change unselected tab text colors.  I have also tried:</p>
  
  <pre><code>tabLayout.setTabTextColors(getResources().getColorStateList(R.color.selector));
  </code></pre>
  
  <p>and </p>
  
  <pre><code>tabLayout.setTabTextColors(R.color.Green, R.color.Blue);
  </code></pre>
  
  <p>Is it possible to override the selected tab text color?</p>
