Xaml 如何创建可用于所有xamarin表单页面的页脚？

我正在创建一个应用程序，其中我希望页脚对于所有xaml页面都是通用的。我尝试了此链接上给出的解决方案

但是它显示了部分类bcoz的错误，我在继承类时使用xamarin-xaml-formpagePageToInherit。如果我只使用page（仅.cs文件），则没有错误

public partial class TodoList : PageToInherit
{
    public TodoList()
    {
        InitializeComponent();
        this.Title = "TodoList page";
        Button button = new Button();
        button.Text = "BUTTON 1";

        MainStackLayout.Children.Add(button);

        Content = MainStackLayout;
    }
}

我想你可以去看看

创建一个控制模板

<?xml version="1.0" encoding="utf-8" ?>
<Application
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="Mobile.App">
  <Application.Resources>
    <ResourceDictionary>
      <ControlTemplate x:Key="MainPageTemplate">
        <StackLayout>
          <Label Text="Header Content" FontSize="24" />         
          <ContentPresenter />
        </StackLayout>
      </ControlTemplate>
    </ResourceDictionary>
  </Application.Resources>
</Application>

对于那些仍在寻找的人

用于创建可重用的xaml视图

<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="xxx.FooterView">
    <ContentView.Content>
        <RelativeLayout VerticalOptions="End" HorizontalOptions="Fill" HeightRequest="42" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}">
                <Label HeightRequest="42" VerticalTextAlignment="Center" Text="Copyright © 2017. All rights reserved." HorizontalTextAlignment="Center" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}" />
            </RelativeLayout>
    </ContentView.Content>
</ContentView>



并像任何控件一样在页面中使用它

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="xxx.Page1" xmlns:local="clr-namespace:xxx;assembly=xxx" >
    <local:FooterView VerticalOptions="End" HeightRequest="45"/>
//other views and layouts
</ContentPage>


//其他视图和布局

希望有帮助。
假设在控制模板中我有四张图像，在图像上单击“希望导航到另一个页面”，我应该在哪里编写代码来处理App.cs或内容页面中的单击事件？我不知道。。。我认为，就像你绑定到HeadingText一样，我认为你可以绑定到命令。
<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="xxx.FooterView">
    <ContentView.Content>
        <RelativeLayout VerticalOptions="End" HorizontalOptions="Fill" HeightRequest="42" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}">
                <Label HeightRequest="42" VerticalTextAlignment="Center" Text="Copyright © 2017. All rights reserved." HorizontalTextAlignment="Center" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}" />
            </RelativeLayout>
    </ContentView.Content>
</ContentView>

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="xxx.Page1" xmlns:local="clr-namespace:xxx;assembly=xxx" >
    <local:FooterView VerticalOptions="End" HeightRequest="45"/>
//other views and layouts
</ContentPage>
