我正在使用xamaring表单构建一个应用程序,但我不能在UWP中更改母版页的标题,它在android上工作正常但不是uwp。
以下是截图:
我想要做的是改变"菜单"的颜色。杆
这是XAML代码:
<MasterDetailPage.Master>
<ContentPage Title="Menu" BackgroundColor="Red">
<StackLayout Orientation="Vertical">
<StackLayout BackgroundColor="#e74c3c" HeightRequest="60">
<Label Text="SomeText"
FontSize="20"
VerticalOptions="CenterAndExpand"
TextColor="White"
HorizontalOptions="Center" />
</StackLayout>
<ListView x:Name="NavigationListView"
RowHeight="60"
SeparatorVisibility="None"
BackgroundColor="#e8e8e8"
ItemSelected="NavigationListView_ItemSelected">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<StackLayout VerticalOptions="FillAndExpand"
Orientation="Horizontal"
Padding="20,10,0,10"
Spacing="20">
<Image Source="{Binding Icon}"
WidthRequest="40"
HeightRequest="40"
VerticalOptions="Center"/>
<Label Text="{Binding Title}"
FontSize="Medium"
VerticalOptions="Center"
TextColor="Black"/>
</StackLayout>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackLayout>
</ContentPage>
</MasterDetailPage.Master>
<MasterDetailPage.Detail>
<Views:MainPage />
</MasterDetailPage.Detail>

实际上,&#34;菜单&#34;的颜色你提到的BarBackgroundColor
吧。因此,您可以为BarBackgroundColor
实例设置NavigationPage
。
<MasterDetailPage.Detail>
<NavigationPage BarBackgroundColor="PowderBlue">
<x:Arguments>
<pages:MasterDetailPageHomeDetail />
</x:Arguments>
</NavigationPage>
</MasterDetailPage.Detail>

为了使我能够正常工作,出于某种原因,我不得不将其设置在隐藏的代码中:
if (Device.RuntimePlatform == Device.UWP) {
BarBackgroundColor = Colour.LighterGray;
BarTextColor = Colour.DarkGray;
}
