我有一个奇怪的问题,我尝试了所有我知道的技巧来居中对齐放置在网格内的 ListView。无论如何,它看起来像是左对齐的。ListView 的宽度和高度是数据绑定的。(宽度可以取值 350 或 700,高度可以取 100 或 200,具体取决于尺寸设置。如果尺寸设置紧凑,则应为 350x100,如果正常则为 700x200)。
这是 xaml 代码
<Grid x:Name="GridPageLVPortrait" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="4" Background="Beige" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="0,0,584.714,0" Width="781">
<ListView x:Name="PageLVPortrait" ItemsSource="{Binding}" CanReorderItems="True" AllowDrop="True" HorizontalAlignment="Center" SelectionMode="Single" IsSwipeEnabled="True" IsItemClickEnabled="True" SelectionChanged="PageLVPortraitSelectionChanged" ItemClick="PageLVPortraitItemClick" Height="{Binding TemplateHeight}" Width="{Binding TemplateWidth}" >
<ListView.ItemTemplate>
<DataTemplate>
<Canvas HorizontalAlignment="Center" Width="{Binding TemplateWidth}" Height="{Binding TemplateHeight}">
<Canvas.Background>
<ImageBrush ImageSource="{Binding PageBackground}"/>
</Canvas.Background>
<Image HorizontalAlignment="Center" Height="{Binding TemplateHeight}" Width="{Binding TemplateWidth}" Source="{Binding Page}" Stretch="None" Opacity="1" CacheMode="BitmapCache" />
<StackPanel x:Name="EditDeleteStackPanel" Width="{Binding TemplateWidth}" Height="{Binding TemplateHeight}" Opacity="0.95">
<Button x:Name="NoteDelete" HorizontalAlignment="Right" VerticalAlignment="Top" Foreground="{x:Null}" Tapped="NoteDelete_Tapped" MinWidth="50" MinHeight="50" Margin="0,0,10,0" BorderBrush="{x:Null}" >
<Button.Background>
<ImageBrush ImageSource="{Binding Delete}"/>
</Button.Background>
</Button>
<Button x:Name="NoteEdit" HorizontalAlignment="Right" VerticalAlignment="Top" FontFamily="Segoe Script" FontSize="24" BorderBrush="{x:Null}" Tapped="NoteEdit_Tapped" Foreground="{x:Null}" MinWidth="50" MinHeight="50" Margin="0,0,10,0">
<Button.Background>
<ImageBrush ImageSource="{Binding Edit}"/>
</Button.Background>
</Button>
</StackPanel>
</Canvas>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
有人可以帮忙吗?
