title: how to set floating label text size?
body: <p>I would like to change floating label text size in Android material <code>EditText</code>, when I set as follows:</p>
  
  <pre><code>&lt;android.support.v7.widget.AppCompatEditText
      android:id="@+id/edt_current"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:hint="@string/str_current"
      android:inputType="number"
      android:singleLine="true"
      android:textSize="20sp" /&gt;
  </code></pre>
  
  <p>It just changes the text size for hint and input Text.</p>
  
  <p>Since, Floating Label Text Size seems too small in my UI, I would like to change it, any solution?</p>
