title: Android style dosen't work
body: <p>I am trying to add a specific style for a button, the issue is that it's works in themes.xml when I write this : </p>
  
  <p><strong>themes.xml</strong></p>
  
  <pre><code>    &lt;style name="AppTheme" parent="Theme.AppCompat.NoActionBar"&gt;
       &lt;item name="colorControlHighlight"&gt;@color/background&lt;/item&gt;
      &lt;item name="colorButtonNormal"&gt;@color/white&lt;/item&gt;
     &lt;/style&gt;
  </code></pre>
  
  <p><strong>mylayout.xml</strong></p>
  
  <pre><code> &lt;Button
      android:id="@+id/play"
      android:layout_width="match_parent"
      android:layout_height="50dp"
      android:layout_alignParentBottom="true"
      android:gravity="center"
      android:text="Play"
      android:textColor="@color/guillotine_background"
      android:textSize="25dp"
      android:textStyle="bold"/&gt;
  </code></pre>
  
  <p>but I don't get the same result when I use this :</p>
  
  <p><strong>styles.xml</strong></p>
  
  <pre><code> &lt;style name="MyColorButton" parent="AppTheme"&gt;
          &lt;item name="colorControlHighlight"&gt;@color/background&lt;/item&gt;
          &lt;item name="colorButtonNormal"&gt;@color/white&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>I added this line to the button tag in mylayout.xml</p>
  
  <p><strong>mylayout.xml</strong></p>
  
  <pre><code>  style="@style/MyColorButton"
  </code></pre>
  
  <p>Isn't that must return the same result ?</p>
