如何创建一个包含示例 a 的“基”,并使它成为应用程序中其他页面的基础?ContentPagebusy indicatorPage
我试图以这种方式做,但没有显示。busy indicator
基本页面:
<?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:core="clr-namespace:SgatMobileV3.Core;assembly=SgatMobileV3"
x:Class="SgatMobileV3.Core.BasePage">
<ContentPage.Content>
<Grid>
<core:VolosLoadingView />
</Grid>
</ContentPage.Content>
</ContentPage>
忙碌指示器视图:
<?xml version="1.0" encoding="UTF-8"?>
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:core="clr-namespace:SgatMobileV3.Core;assembly=SgatMobileV3"
core:LocatorViewModel.AutoWireViewModel="true"
x:Class="SgatMobileV3.Core.VolosLoadingView"
xmlns:busyindicator="clr-namespace:Syncfusion.SfBusyIndicator.XForms;assembly=Syncfusion.SfBusyIndicator.XForms">
<Grid>
<Grid BackgroundColor="LightGray" Opacity="0.6" IsVisible="True" />
<busyindicator:SfBusyIndicator
IsBusy="True"
IsVisible="True"
x:Name="loading" AnimationType="DoubleCircle"
ViewBoxWidth="150" ViewBoxHeight="150"
TextColor="Green" BackgroundColor="Transparent"
HorizontalOptions="Center" VerticalOptions="Center"/>
</Grid>
</ContentView>
我试图在基本页面中包含一个示例,但没有显示任何内容。label
