title: Hint text doesn´t appear in my Text Edit
body: <p>I'm working on some views for my Android and trying to implement floating labels in text edit field, but even thought the label show when the element is focused, it doesn't show while it's not.</p>
  
  <p>When it's not focused:</p>
  
  <p><a href="https://i.stack.imgur.com/DbaqUl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/DbaqUl.png" alt=""></a></p>
  
  <p>When it's focused:</p>
  
  <p><a href="https://i.stack.imgur.com/8fhcyl.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8fhcyl.png" alt=""></a></p>
  
  <p>And this is the code</p>
  
  <pre><code>&lt;android.support.design.widget.TextInputLayout
      android:id="@+id/input_layout_password"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
  
      &lt;EditText
          android:id="@+id/input_plate"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:hint="Placas"
          android:textColorHint="@color/s_gray"
          android:ellipsize="end"
          /&gt;
  
  &lt;/android.support.design.widget.TextInputLayout&gt;
  </code></pre>
