如何繪製3列的網格，其中2列的大小爲內容？

Question

所以我想畫一個網格3列，這樣我可以有：

Cancel Title Save

但此刻我得到

Cancel Title Save

我的代碼是：

var modalContentPage = sender as ModalContentPage; 
var context = Android.App.Application.Context; 
var actionBar = ((Activity)Context).ActionBar; 
LinearLayout gridView = new LinearLayout(context); 
gridView.SetGravity(GravityFlags.FillHorizontal|GravityFlags.CenterVertical); 
LinearLayout.LayoutParams textViewParameters = 
      new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MatchParent, LinearLayout.LayoutParams.MatchParent); 

Android.Widget.Button cancelButton = new Android.Widget.Button(context); 
cancelButton.Text = "Cancel"; 
cancelButton.Click += delegate 
{ 
    modalContentPage.CancelCommand.Execute(null); 
}; 
gridView.AddView(cancelButton, LayoutParams.WrapContent); 

TextView modelTitle = new TextView(context); 
modelTitle.Text = actionBar.Title; 
modelTitle.TextFormatted = actionBar.TitleFormatted; 
modelTitle.Gravity = GravityFlags.Center; 
modelTitle.TextSize = 25; 
modelTitle.SetTypeface(Android.Graphics.Typeface.Default, Android.Graphics.TypefaceStyle.Bold); 
modelTitle.SetTextColor(Android.Graphics.Color.White); 
gridView.AddView(modelTitle); 

Android.Widget.Button saveButton = new Android.Widget.Button(context); 
saveButton.Text = "Save"; 
saveButton.Click += delegate 
{ 
    modalContentPage.SaveCommand.Execute(null); 
}; 
saveButton.Background.SetColorFilter((Resources.GetColor(Resource.Color.accent)),Android.Graphics.PorterDuff.Mode.Multiply); 
saveButton.Gravity = GravityFlags.Center; 
gridView.AddView(saveButton,LayoutParams.WrapContent); 

ActionBar.LayoutParams actionbarParams = 
      new ActionBar.LayoutParams(ActionBar.LayoutParams.MatchParent, ActionBar.LayoutParams.MatchParent); 
actionBar.SetCustomView(gridView, actionbarParams); 
actionBar.SetDisplayShowCustomEnabled(true); 
actionBar.SetIcon(new ColorDrawable(Color.Transparent.ToAndroid())); 
actionBar.SetDisplayHomeAsUpEnabled(false);

我需要補充的是：

modelTitle.LayoutParameters = new TableRow.LayoutParams(0, LayoutParams.WrapContent, 1f);
