title: Android: TextView.setTextAppearance() does not effect text size
body: <p>Running on my Samsung Galaxy Note, the below code logs 28.0 for each log statement.  Am I doing something wrong?</p>
  
  <pre><code>label = new TextView(context);
  Log.e("text size", "" + label.getTextSize());
  
  label.setTextAppearance(context, android.R.attr.textAppearanceLarge);
  Log.e("text size", "" + label.getTextSize());
  
  label.setTextAppearance(context, android.R.attr.textAppearanceSmall);
  Log.e("text size", "" + label.getTextSize());
  </code></pre>
