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。
