title: TextView textSize behaving differently now
body: <p>The documentation for <code>setTextSize()</code> on TextView says, effectively, that it is expecting units of "SP".  I have <code>TextViews</code> that set their <code>textSize</code> attribute through databinding.  When I updated Android Studio today to 3.1, the behavior seems to have changed and <code>setTextSize()</code> now seems to expect pixels.  Is anyone else seeing?</p>
