Xamarin列表视图中显示不正确iOS上

Question

我有以下XAML

 <StackLayout Orientation="Vertical" VerticalOptions="EndAndExpand" HorizontalOptions="FillAndExpand" Margin="0,0,0,0"> 
     <Label Text="Menu" /> 

     <ListView x:Name="lvMenu" ItemSelected="lvMenu_ItemSelected"> 
      <ListView.ItemTemplate> 
      <DataTemplate> 
       <ImageCell ImageSource="{Binding ImageSource}" Text="{Binding TitleText}" /> 
      </DataTemplate> 
      </ListView.ItemTemplate> 
     </ListView> 
     </StackLayout> 

下面的C＃填充它

private void PopulateMenu() 
    { 
     var menu = new List<SettingItem>() 
     { 
      new SettingItem() { ImageSource="icon.png", TitleText="Show All Jobs", TargetPageType = typeof(JobListPage) }, 
      new SettingItem() { ImageSource="opportunities.png", TitleText="Sync Tasks", TargetPageType = typeof(SyncPage) }, 
      new SettingItem() { ImageSource="leads.png", TitleText="Advanced Settings", TargetPageType = typeof(SettingsPage) }, 
      new SettingItem() { ImageSource="contacts.png", TitleText="About ", TargetPageType = typeof(AboutPage) }, 
     }; 
     lvMenu.ItemsSource = menu; 
    } 

其所有的好，但它显示，当我得到

Menu 
    Show All Jobs 
    Sync Tasks 
    Advanced Settings 

和iOS模拟器上的7个空白行

Answer 1

iOS上ListView的默认行为是添加空行。

为了克服这一点，你需要用你的ListView在一个StackPanel，

或创建渲染自定义：

protected override void OnElementChanged(ElementChangedEventArgs<ListView> e) 
{ 
    base.OnElementChanged(e); 

    if (this.Control == null) return; 

    this.Control.TableFooterView = new UIView(); 
}
