title: change text color on disabled button (custom ButtonRenderer)
body: <p>I use <code>Xamarin.Forms</code>, I create custom Renderer <code>FlatButtonRenderer</code> for Android. I want to add to it only one parametr - white text color on disabled button. What easy way to do it? On enabled button I simple can change <code>Button.TextColor</code> in <code>PCL</code> project. If way to change text color on disabled with c# code?</p>
  
  <pre><code>using Xamarin.Forms.Platform.Android;
  using Xamarin.Forms;
  
  [assembly: ExportRenderer(typeof(Button), typeof(ugrid.Droid.FlatButtonRenderer))]
  
  namespace myProject.Droid
  {
      public class FlatButtonRenderer : ButtonRenderer
      {
          protected override void OnDraw(Android.Graphics.Canvas canvas)
          {
              base.OnDraw(canvas);
          }
  
          protected override void OnElementChanged(ElementChangedEventArgs&lt;Button&gt; e)
          {
              base.OnElementChanged(e);
          }
      }
