我想输出 3 个控件,一个 Label、一个 ImageButton 和另一个 Label,并且第一个 Label 位于布局的左侧,ImageButton 和第二个标签位于右侧,但始终组合在一起。我尝试了多种方法来执行此操作,但没有一种方法可以保持标签和图像按钮/标签的左/右方向。在我的一次尝试中,我做了以下事情:

        <StackLayout>
<!-- Header -->
<headersAndFooters:MainHeaderSmall ConfigName="IdCard"/>
<!-- Body -->
<ScrollView>
<StackLayout Margin="-10, 0, -10, 0" HeightRequest="614" >
<!-- -->
<Label LineHeight="19"
Margin="24, 21, 0, 0"
Text="ID Card for 2019 Jeep Wrangler"
FontFamily="{StaticResource HBold}"
FontSize="{StaticResource Font16}"
TextColor="{StaticResource NGIC_DarkGray}"/>
<FlexLayout x:Name="Problem" Direction="Row"
Margin="24, 4, 0, 0">
<Label LineHeight="18"
Text="Back Side"
FontFamily="{StaticResource HNRegular}"
FontSize="{StaticResource Font14}"
TextColor="{StaticResource NGIC_GrayishBlue}"/>
<StackLayout Orientation="Horizontal">
<ImageButton Margin="200, 0, 0, 0" BackgroundColor="Transparent"
WidthRequest="11"
HeightRequest="11"
Aspect="AspectFit"
HorizontalOptions="Start"
VerticalOptions="Center">
<ImageButton.Source>
<FontImageSource
FontFamily="FAProSolid"
Glyph="{x:Static local:IconFontsFAProRegular.Sync}"
Size="{StaticResource Font11}"
Color="{StaticResource NGIC_Red}" />
</ImageButton.Source>
</ImageButton>
<Label Margin="3, 0,0,0"
Text="See Front"
LineHeight="16"
HorizontalTextAlignment="End"
TextDecorations="Underline"
FontFamily="{StaticResource HNRegular}"
FontSize="{StaticResource Font13}"
TextColor="{StaticResource NGIC_Red}"/>
</StackLayout>
</FlexLayout>
</StackLayout>
</ScrollView>
</StackLayout>

此布局的输出在较低的设备分辨率下看起来不错,但 ImageButton 和右侧标签不在右侧的末尾。

在更宽的设备上,图像按钮/标签甚至不会接近布局的最右侧。

我还尝试在 StackLayout 内部使用网格(名为“Problem”的网格),但这也不起作用。右侧图像按钮/标签在更高分辨率下不会保持在布局的右侧。

更新:

                                <Grid>
<Grid.RowDefinitions>
<RowDefinition Height="18*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="251*" />
<ColumnDefinition Width="73*" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0"
Grid.Column="0"
LineHeight="18"
Text="Back Side"
FontFamily="{StaticResource HNRegular}"
FontSize="{StaticResource Font14}"
TextColor="{StaticResource NGIC_GrayishBlue}"/>
<ImageButton Grid.Row="0" Grid.Column="1" BackgroundColor="Transparent"
WidthRequest="11"
HeightRequest="11"
Aspect="AspectFit"
HorizontalOptions="Start"
VerticalOptions="Center">
<ImageButton.Source>
<FontImageSource
FontFamily="FAProSolid"
Glyph="{x:Static local:IconFontsFAProRegular.Sync}"
Size="{StaticResource Font11}"
Color="{StaticResource NGIC_Red}" />
</ImageButton.Source>
</ImageButton>
<Label Grid.Row="0" Grid.Column="1" Margin="3, 0,0,0"
Text="See Front"
LineHeight="16"
HorizontalTextAlignment="End"
TextDecorations="Underline"
FontFamily="{StaticResource HNRegular}"
FontSize="{StaticResource Font13}"
TextColor="{StaticResource NGIC_Red}"/>
</Grid>

最佳答案

这是一个简单的示例,可以实现您想要的功能。调试布局时,在不同层上设置背景颜色非常有帮助,这样您就可以直观地看到每个元素在其父元素中的布局方式

<ContentPage BackgroundColor="Blue" xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:d="http://xamarin.com/schemas/2014/forms/design" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="LayoutTest.MainPage">
<Grid Padding="10,50,10,10" BackgroundColor="Green">
<Grid.RowDefinitions>
<RowDefinition Height="200" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*" />
<ColumnDefinition Width="50*" />
</Grid.ColumnDefinitions>
<Label BackgroundColor="Yellow" Grid.Row="0" Grid.Column="0" Text="Left Align" />
<StackLayout BackgroundColor="Orange" Grid.Row="0" Grid.Column="1">
<Label BackgroundColor="Purple" HorizontalOptions="End" Text="Right Align" />
<Button BackgroundColor="Red" HorizontalOptions="End" Text="Right Align" />
</StackLayout>
</Grid>
</ContentPage>

enter image description here

要将它们垂直对齐,请尝试此操作

<Label BackgroundColor="Yellow" VerticalOptions="Center" Grid.Row="0" Grid.Column="0" Text="Left Align" />
<StackLayout Orientation="Horizontal" VerticalOptions="Center" HorizontalOptions="End" BackgroundColor="Orange" Grid.Row="0" Grid.Column="1">
<Label BackgroundColor="Purple" VerticalOptions="Center" Text="Right Align" />
<Button BackgroundColor="Red" VerticalOptions="Center" Text="Right Align" />
</StackLayout>
