I've tried to use xcc https://github.com/firstfloorsoftware/xcc , but it seems not working with .netstandard 2.0 / Xamarin.Forms 4.5我尝试使用 xcc https://github.com/firstfloorsoftware/xcc ,但它似乎不适用于 .netstandard 2.0 / Xamarin.Forms 4.5
Its little different in XAML of Xamarin.它在 Xamarin 的 XAML 中略有不同。 There is Design time namespacing in Xamarin.
Xamarin 中有设计时命名空间。
You would use markup-compatibility xml name space and mark design namespace as Ignorable
您将使用标记兼容性xml 命名空间并将设计命名空间标记为可
Ignorable
<?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:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://xamarin.com/schemas/2014/forms/design"
xmlns:ref="clr-namespace:XamUtilities.Views;assembly=XamUtilities"
mc:Ignorable="d"
x:Class="Sample.MainPage">
<ContentPage.Content>
<d:Label Text="This will be displayed only in previewer"/>
<Label Text="This will be displayed in actual app"/>
</ContentPage.Content>
</ContentPage>
In code behind also you can set values在后面的代码中,您也可以设置值
[DesignTimeVisible (true)]
public partial class MainPage : ContentPage
{
public MainPage ()
{
InitializeComponent ();
if (DesignMode.IsDesignModeEnabled)
{
// Previewer only code
//add your bindings in here
}
}
}
