title: TextInputLayout and AutoCompleteTextView background looks fine in preview, but on device it is always white
body: <p>To keep it as short as possible.</p>
  
  <p>This is my style for TextInputLayout</p>
  
  <pre><code>&lt;style name="TextLabel" parent="Widget.AppCompat.AutoCompleteTextView"&gt;
      &lt;!-- Hint color and label color in FALSE state --&gt;
      &lt;item name="android:textColorHint"&gt;@color/pure_white&lt;/item&gt;
      &lt;!-- Label color in TRUE state and bar color FALSE and TRUE State --&gt;
      &lt;item name="colorAccent"&gt;@color/pure_white&lt;/item&gt;
      &lt;item name="colorControlNormal"&gt;@color/pure_white&lt;/item&gt;
      &lt;item name="colorControlActivated"&gt;@color/pure_white&lt;/item&gt;
      &lt;!-- When everything else failed I tried this but with no effect --&gt;
      &lt;item name="android:background"&gt;@android:color/transparent&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>And this is the implementation in the layout</p>
  
  <pre><code>    &lt;android.support.design.widget.TextInputLayout
          android:theme="@style/TextLabel"
          android:layout_margin="@dimen/activity_margin_basic_double"
          android:layout_centerInParent="true"
          android:id="@+id/team_name_container"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"&gt;
  
          &lt;AutoCompleteTextView
              android:id="@+id/new_team_name"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:hint="@string/prompt_team_create"
              android:maxLines="1" /&gt;
  
      &lt;/android.support.design.widget.TextInputLayout&gt;
  </code></pre>
  
  <p>And this is what I get on the device (both physical and emulated):

  <p>But this is what I actually want and Android Studio preview actually shows it correctly, it just won't compile this way:</p>

  <p>Any ideas how to get this sorted please? I've wasted few days trying to figure this one out but just can't figure the problem</p>
  
  <p>Many thanks in advance!
