我需要创建一个标准的布局,我可以在许多页面上使用,但传递的内容显示在里面。。。我的成功有限 下面是我如何调用自定义控件Xamarin,具有布局的自定义控件,在特定位置接受可绑定内容,xamarin,xamarin.forms,Xamarin,Xamarin.forms,我需要创建一个标准的布局,我可以在许多页面上使用,但传递的内容显示在里面。。。我的成功有限 下面是我如何调用自定义控件 <?xml version="1.0" encoding="utf-8"?> <ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.c
<?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:control="clr-namespace:myApp"
x:Class="myApp.MainPage">
<StackLayout>
<control:CustomPopupLayoutControl
BackgroundColor="LightGreen">
<control:CustomPopupLayoutControl.Content>
<Button Text="Hello" />
<!-- lots of other controls, buttons, labels etc, layout -->
</control:CustomPopupLayoutControl.Content>
</control:CustomPopupLayoutControl>
</StackLayout>
</ContentPage>
<?xml version="1.0" encoding="UTF-8"?>
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"

<ContentView.Content>
<StackLayout BackgroundColor="LightBlue" Margin="30">
<Button Text="Close" /><!-- important-->
<!-- lots of other layout -->
<StackLayout BackgroundColor="Red" x:Name="Inner">
</StackLayout>
</StackLayout>
</ContentView.Content>
</ContentView>
所以你可以看到这里我不想显示一些内容
这是我的自定义控件
<?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:control="clr-namespace:myApp"
x:Class="myApp.MainPage">
<StackLayout>
<control:CustomPopupLayoutControl
BackgroundColor="LightGreen">
<control:CustomPopupLayoutControl.Content>
<Button Text="Hello" />
<!-- lots of other controls, buttons, labels etc, layout -->
</control:CustomPopupLayoutControl.Content>
</control:CustomPopupLayoutControl>
</StackLayout>
</ContentPage>
<?xml version="1.0" encoding="UTF-8"?>
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="myApp.CustomPopupLayoutControl"
x:Name="CustomPopupLayouts">
<ContentView.Content>
<StackLayout BackgroundColor="LightBlue" Margin="30">
<Button Text="Close" /><!-- important-->
<!-- lots of other layout -->
<StackLayout BackgroundColor="Red" x:Name="Inner">
</StackLayout>
</StackLayout>
</ContentView.Content>
</ContentView>
所以我想在内部堆栈布局中显示我的hello按钮,我还需要绑定才能工作
所以最后一页应该看起来像
<page>
<StackLayout BackgroundColor="LightBlue" Margin="30">
<Button Text="Close" /><!-- important-->
<StackLayout BackgroundColor="Red">
<button text="Hello">
</StackLayout>
<StackLayout>
</page>
由于您在自定义控件中定义了一个按钮,因此只需将要显示在按钮上的标题从ContentPage传递到自定义控件即可 在CustomPopulLayoutControl.xaml中 在ContentPage中 您可以直接设置按钮的标题,也可以使用数据绑定
<control:CustomPopupLayoutControl ButtonTitle = "Hello World!" BackgroundColor="LightGreen" / >
我找到了一个解决方案:)
您可以发布解决方案并接受它,或者用您的解决方案编辑我的答案。
