[英]reduce spacing between ListView Items in Xamarin forms
我在xamarin便携式应用程序中有此列表,我似乎无法删除或至少减少项目之间的间距,并且也禁用项目选择。
<ListView x:Name="ListGroups"
ItemsSource="{Binding Source={x:Static local:Stash.Groups}}"
HorizontalOptions="Center" >
<ListView.ItemTemplate>
<DataTemplate >
<ViewCell>
<Label Text="{Binding Name}" TextColor="Aqua" FontSize="10" HorizontalOptions="Center" />
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
然后是一些标签
<Label Text="If you feel you're missing"
FontSize="15"
VerticalOptions="Center"
HorizontalOptions="Center"
TextColor="White"
/>
<Label Text="a group or two, please contact"
FontSize="15"
VerticalOptions="Center"
HorizontalOptions="Center"
TextColor="White"
/>
<Label Text="your manager"
FontSize="15"
VerticalOptions="Center"
HorizontalOptions="Center"
TextColor="White"
/>
</StackLayout>
你可以尝试
HasUnevenRows = "true"
对于“禁用选择”,您可以按照以下步骤操作
SelectionDemoList.ItemSelected += (sender, e) => {
((ListView)sender).SelectedItem = null;
};
请注意,在Windows Phone上,包括SwitchCell在内的某些单元不会响应选择而更新其可视状态。
要降低ListView的高度,可以使用网格。 这是一个样本
