Hi,

i am using the following code to align action bar title in the center in xamarin c# cross platoform application.

public static void SetActionbarText(Activity activity, string text)
       {
           // Setting custom view enable
           if (activity != null)
           {
               activity.ActionBar.SetHomeButtonEnabled(true);
               activity.ActionBar.SetIcon(Android.Resource.Color.Transparent);
               activity.ActionBar.SetDisplayShowCustomEnabled(true);

               LinearLayout linearLayout = new LinearLayout(activity);
               linearLayout.SetGravity(GravityFlags.CenterVertical);
               LinearLayout.LayoutParams textViewParameters =
                   new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MatchParent, LinearLayout.LayoutParams.MatchParent);
               textViewParameters.RightMargin = (int)(40 * activity.Resources.DisplayMetrics.Density);
               TextView modelTitle = new TextView(activity);
               modelTitle.Text = text;
               modelTitle.Gravity = GravityFlags.Center;
               modelTitle.TextSize = 20;
               modelTitle.SetTextColor(Android.Graphics.Color.White);
               linearLayout.AddView(modelTitle, textViewParameters);
               ActionBar.LayoutParams actionbarParams =
                   new ActionBar.LayoutParams(ActionBar.LayoutParams.MatchParent, ActionBar.LayoutParams.MatchParent);
               activity.ActionBar.SetCustomView(linearLayout, actionbarParams);
           }
       }

this works fine in portrait mode but not in landscape mode. the title moves to right side in landscape mode and once we change orientation it hides completly. Can anyone check what i am missing?
