title: How to stop Facebook SDK Dialog using white textcolor even if my theme needs white text
body: <p>As much as I learn, I still have a long way to go ...</p>
  
  <p>I'm trying to use Facebook SDK to provide details for a sign up.</p>
  
  <p>I am using a blue, yellow and white theme for my app; the text being white. My style setup is:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
      &lt;!-- Customize your theme here. --&gt;
      &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
      &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
      &lt;item name="colorAccent"&gt;@android:color/holo_orange_light&lt;/item&gt;
      &lt;item name="android:colorBackground"&gt;@color/colorMainBackground&lt;/item&gt;
      &lt;!--&lt;item name="android:actionBarStyle"&gt;@style/ThemeActionBar&lt;/item&gt;--&gt;
      &lt;!--&lt;item name="android:windowActionBarOverlay"&gt;true&lt;/item&gt;--&gt;
      &lt;item name="android:textColor"&gt;@android:color/white&lt;/item&gt;
      &lt;item name="android:textColorLink"&gt;@android:color/holo_orange_light&lt;/item&gt;
      &lt;!-- Support library compatibility --&gt;
      &lt;!--&lt;item name="actionBarStyle"&gt;@style/ThemeActionBar&lt;/item&gt;--&gt;
      &lt;!--&lt;item name="windowActionBarOverlay"&gt;true&lt;/item&gt;--&gt;
      &lt;item name="android:textColorPrimary"&gt;@android:color/white&lt;/item&gt;
      &lt;item name="android:titleTextColor"&gt;@color/yellow&lt;/item&gt;
      &lt;item name="android:textColorPrimaryInverse"&gt;@android:color/black&lt;/item&gt;
      &lt;item name="android:navigationBarColor"&gt;?android:attr/statusBarColor&lt;/item&gt;
      &lt;item name="android:textColorSecondary"&gt;@android:color/white&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>However, when Facebook shows a dialog box, all I get is a white square:</p>
  
  <p><a href="https://i.stack.imgur.com/aWphF.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aWphF.jpg" alt="enter image description here"></a></p>
  
  <p>It would appear that Facebook are using my textcolor and hence the white box. Is there a way I can override this? Or have Facebook use the default colour scheme (if there is one).</p>
  
  <p>This is somewhat frustrating me now.</p>
  
  <p>My Manifest entry for Facebook is:</p>
  
  <pre><code>    &lt;activity
          android:name="com.facebook.FacebookActivity"
          android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
          android:label="@string/app_name" /&gt;
  </code></pre>
  
  <p>Thanks in advance</p>
