title: Overriding text color for buttons not working
body: <p>I've created a custom theme for a button bar using buttonBarStyle on each button and buttonBarButtonStyle on the layout.
  It works fine, but i want to change the text color for the buttons, but it still takes the default color (@android:color/primary_text_holo_light)
  My code is:</p>
  
  <pre><code>&lt;style name="ButtonBarTheme" parent="AppTheme"&gt;
          &lt;item name="buttonBarStyle"&gt;?android:attr/buttonBarStyle&lt;/item&gt;
          &lt;item name="buttonBarButtonStyle"&gt;?android:attr/buttonBarButtonStyle&lt;/item&gt;
          &lt;item name="android:textColor"&gt;#ffffff&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>And for the layout:</p>
  
  <pre><code>&lt;LinearLayout 
      style="?android:attr/buttonBarStyle"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="#0090cc"
      android:orientation="horizontal" &gt;
  
      &lt;Button
          android:id="@+id/bar_button1"
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          style="@style/ButtonBarStyleButton"
          android:text="Button 1" /&gt;
  
      &lt;Button
          android:id="@+id/bar_button2"
          android:layout_width="0dp"
          android:layout_height="wrap_content"
          android:layout_weight="1"
          style="?android:attr/buttonBarButtonStyle"
          android:text="Button 2" /&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>AppTheme has parent AppBaseTheme, which has parent android:Theme.Holo.Light.DarkActionBar.</p>
  
  <p>What do I have to do to change the buttons' text color?</p>
  
  <p><strong>EDIT:</strong>
  I tried applying the color on each element and it works, but I want to change it by overriding the color in the style file (keep all design properties in one place, similar to CSS).</p>
  
  <p>Also, I have tried to create a style that has the properties of ?android:attr/buttonBarStyle"</p>
  
  <pre><code>   &lt;style name="ButtonBarStyleButtonBase"&gt;
          &lt;item name="buttonBarButtonStyle"&gt;?android:attr/buttonBarButtonStyle&lt;/item&gt;
      &lt;/style&gt;
  
     &lt;style name="ButtonBarStyleButton" parent="ButtonBarStyleButtonBase"&gt;
          &lt;item name="android:textColor"&gt;#ffFFff&lt;/item&gt;
      &lt;/style&gt;
  </code></pre>
  
  <p>but it behaves strangely: the color is updated, but no properties form the parent style are visible.</p>
