【问题描述】:
我有如下内容视图
<?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:convertors="clr-namespace:myApp.Convertors;assembly=myApp"
x:Class="myApp.cwPart">
<ContentView.Content>
<StackLayout Orientation="Horizontal"
BackgroundColor="White">
<RelativeLayout Style="{StaticResource myStyle}"
HorizontalOptions="Start"
VerticalOptions="Center">
我在多个ContentPages 中引用了这个ContentView,作为下面的示例。每个ContentPage 应该设置不同的BackgroundColor、Height 和Width。这就是为什么我认为应该在ContentPage 中定义样式,但它会引发错误,即无法识别。我怎样才能做到这一点?
PS,有趣的是我正在使用 Gorilla 播放器来实现这样的更改,而 Gorilla 播放器没有返回任何错误:)
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:convertors="clr-namespace:myApp.Convertors;assembly=myApp"
xmlns:c="clr-namespace:myApp;assembly=myApp"
x:Class="myApp.AppLogsPage"
Title="{Binding AppName}"
x:Name="AppLogsPage">
<ContentPage.Resources>
<ResourceDictionary>
<Style x:Key="myStyle" TargetType="RelativeLayout">
<Setter Property="HeightRequest" Value="148"/>
<Setter Property="WidthRequest" Value="80"/>
<Setter Property="BackgroundColor" Value="White"/>
</Style>
</ResourceDictionary>
</ContentPage.Resources>
<ContentPage.Content>
<StackLayout x:Name="MainHolder">
<c:cwPart />
...
如果我如下定义 ContentView 资源,它可以正常工作,但我无法覆盖 ContentView 中定义的样式
<?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:convertors="clr-namespace:myApp.Convertors;assembly=myApp"
x:Class="myApp.cwPart">
<ContentView.Resources>
<ResourceDictionary>
<Style x:Key="myStyle" TargetType="RelativeLayout">
<Setter Property="HeightRequest" Value="148"/>
<Setter Property="WidthRequest" Value="80"/>
<Setter Property="BackgroundColor" Value="White"/>
</Style>
</ResourceDictionary>
</ContentView.Resources>
<ContentView.Content>
<StackLayout Orientation="Horizontal" BackgroundColor="White">
<RelativeLayout Style="{StaticResource myStyle}"
HorizontalOptions="Start" VerticalOptions="Center" >
