フォームにツールバーが表示される問題があります。フォームはConfigurationPage.csです。私はConfigurationPageとページ自体に移動するページを含めています。ツールバーが表示されない理由は何ですか？Xamarin - フォームにツールバーが表示されない
のApp節
public App()
{
// The root page of your application
MainPage = new NavigationPage(new MainPage());
}
メインページ
public class MainPage : ContentPage
{
public MainPage()
{
BackgroundColor = Color.White;
var setup = new Button
{
Text = "Lane Configuration",
TextColor = Color.Black
};
setup.Clicked += (sender, args) =>
{
Navigation.PushModalAsync(new ConfigurationPage());
};
var gateGridLayout = new Grid
{
Padding = new Thickness(5),
VerticalOptions = LayoutOptions.CenterAndExpand,
HorizontalOptions = LayoutOptions.CenterAndExpand,
RowDefinitions = {new RowDefinition{ Height = new GridLength (1, GridUnitType.Auto) }},
ColumnDefinitions = {new ColumnDefinition{ Width = GridLength.Auto }}
};
gateGridLayout.Children.Add(setup, 0, 0);
Content = gateGridLayout;
