title: textColor defined in style not being applied to button text
body: <p>I have a several buttons in my application and I want to apply a style to all of them. </p>
  
  <p>The following is my styles.xml file which I placed in my values folder. </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  
   &lt;resources&gt;
  
       &lt;style name="buttonStyle"&gt;
        &lt;item name="android:textStyle"&gt; bold &lt;/item&gt;
        &lt;item name="android:textColor"&gt; #282780 &lt;/item&gt;
        &lt;item name="android:textSize"&gt; 20sp &lt;/item&gt;
       &lt;/style&gt;
  
  &lt;/resources&gt;
  </code></pre>
  
  <p>And in my layout xml file I use the style within the button as follows, </p>
  
  <pre><code>&lt;Button android:id="@+id/ok_preview_appointment_button" 
          android:text="@string/ok_preview_appointment_button"
          android:layout_width="175dp"
          android:layout_height="35dp"
          android:layout_marginBottom="10dp"
          style="@style/buttonStyle"
          android:background="@drawable/button_background" /&gt;
  </code></pre>
  
  <p>I get the following error "java.lang.NumberFormatException: Color value ' #282780 ' must start with #"</p>
  
  <p>I checked out other threads but they all seem to encounter this problem when they use @color which is not my case. </p>
  
  <p>Thank you in advance! </p>
