Maui中斜体文本末尾被截断问题求助

问题现象 #

带有Bold,Italic属性的Label控件文本末尾被截断，控件计算布局空间时未考虑斜体字体向右倾斜延伸的额外宽度，导致右侧字符无法完整显示。

修复方法 #

• 给斜体Label添加右侧内边距，预留斜体延伸的空间
• 调整HorizontalOptions为Fill，让Label占据单元格全部宽度，配合居中对齐确保文本有足够展示空间

调整后的XAML代码 #

<Grid BackgroundColor="{Binding color}" ColumnDefinitions="*,*" RowDefinitions="Auto,Auto,Auto,Auto" >
    <Grid.GestureRecognizers>
        <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped" NumberOfTapsRequired="1" CommandParameter="{Binding trackName}"></TapGestureRecognizer>
        <TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped_1"  NumberOfTapsRequired="2" CommandParameter="{Binding trackName}"></TapGestureRecognizer>
    </Grid.GestureRecognizers>
    <Label Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="0" 
           Text="{Binding trackName}" TextColor="Black" FontSize="Large" 
           FontAttributes="Bold" HorizontalTextAlignment="Center" 
           HorizontalOptions="CenterAndExpand" VerticalTextAlignment="Center" />
    <!-- 给斜体Label添加右侧内边距，调整布局选项 -->
    <Label Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1"  
           Text="{Binding raceName}" TextColor="White" FontSize="Medium" 
           FontAttributes="Bold,Italic" HorizontalTextAlignment="Center" 
           HorizontalOptions="Fill" Padding="0,0,8,0" VerticalTextAlignment="Center" />
    <Label Grid.Column="0" Grid.ColumnSpan="1" Grid.Row="2"  
           Text="{Binding round}" TextColor="White" FontSize="Medium" 
           FontAttributes="Bold,Italic" HorizontalTextAlignment="Center" 
           HorizontalOptions="Fill" Padding="0,0,8,0" VerticalTextAlignment="Center" />
    <Label Grid.Column="1" Grid.ColumnSpan="1" Grid.Row="2"  
           Text="{Binding pair}" TextColor="White" FontSize="Medium" 
           FontAttributes="Bold,Italic" HorizontalTextAlignment="Center" 
           HorizontalOptions="Fill" Padding="0,0,8,0" VerticalTextAlignment="Center" />
    <Label Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="3"  
           Text="{Binding lastResult}" TextColor="{Binding colorResult}" FontSize="Medium" 
           FontAttributes="Bold,Italic" HorizontalTextAlignment="Center" 
           HorizontalOptions="Fill" Padding="0,0,8,0" VerticalTextAlignment="Center" />
</Grid>

补充说明 #

• 内边距数值8可根据实际字体大小调整，确保斜体延伸部分完全显示
• 若上述方法仍无法解决，可针对不同平台编写自定义渲染器，修改文本测量逻辑以适配斜体字体
