Xamarin XAML语言教程构建ControlTemplate控件模板 (二)

(2)打开MainPage.xaml文件,编写代码,将构建的控件模板应用于ContentView中。代码如下:

  • <?xml version="1.0" encoding="utf-8" ?>
  • <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
  • xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
  • xmlns:local="clr-namespace:ControlTemplateDemo"
  • x:Class="ControlTemplateDemo.MainPage">
  • <ContentView x:Name="contentView"
  • Padding="0,20,0,0"
  • ControlTemplate="{StaticResource TealTemplate}">
  • <StackLayout Spacing="20"
  • VerticalOptions="Center">
  • <Label Text="If a jewel falls into the mire, it remains as precious as before; and though dust should ascend to heaven, its former worthlessness will not be altered."
  • FontSize="20"
  • FontAttributes="Bold"/>
  • <Button Text="改变主题"
  • Clicked="OnButtonClicked" />
  • </StackLayout>
  • </ContentView>
  • </ContentPage>

在此代码中TealTemplate控件模板通过使用StaticResource标记扩展分配给ContentView.ControlTemplate属性。ContentView.Content属性设置为StackLayout,用于定义要在ContentPage上显示的内容。 此内容将由TealTemplate中包含的ContentPresenter显示。
