UWP 实现Tab导航首页
先看效果：
这个是用Pivot来实现
1、自定义Pivot的样式，使用Blend工具生成模板，将HeaderTemplate的布局都隐藏
1 <Style x:Key="PivotStyle1" TargetType="Pivot"> 2 <Setter Property="Margin" Value="0"/> 3 <Setter Property="Padding" Value="0"/> 4 <Setter Property="Background" Value="{ThemeResource

和ListView一样，通过 ItemTemplateSelector 定制4个TabView模板
3、MainViewModel代码
1 using GalaSoft.MvvmLight; 2 using Demo.UWP.Models; 3 using System; 4 using System.Collections.Generic; 5 using System.Collections.ObjectModel; 6 using System.Linq; 7 using System.Text; 8 using System.Threading.Tasks; 9 using Windows.UI.Xaml.Media.Imaging; 10 using GalaSoft.MvvmLight.Command; 11 using Windows.UI.Popups; 12 using Windows.UI.Xaml; 13 using Demo.UWP.Controls; 14 15 namespace Demo.UWP.ViewModels 16 { 17 public class MainViewModel : ViewModelBase 18 { 19 private int _SelectedIndex; 20 21 public int SelectedIndex 22 { 23 get { return _SelectedIndex; } 24 set 25 { 26 Set<int>(ref _SelectedIndex, value); 27 } 28 } 29 30 public ObservableCollection<ViewModelBase> Data { get; set; } 31 32 public MainViewModel() 33 { 34 Data = new ObservableCollection<ViewModelBase> 35 { 36 new HomeViewModel() {Type = 1, Title = "首页"}, 37 new CouponTabViewModel() {Type = 2, Title = "品质优惠"}, 38 new FindTabViewModel() {Type = 3, Title = "发现"}, 39 new MineViewModel() {Type = 4, Title = "我的"} 40 }; 41 SelectedIndex = 0; 42 } 43 44 public string Home => "首页"; 45 46 public RelayCommand<RoutedEventArgs> HomeTab_Checked => new RelayCommand<RoutedEventArgs>((e) => 47 { 48 //RadioImageButton radio = e.OriginalSource as RadioImageButton; 49 //if (radio.IsChecked.Value) 50 //{ 51 // SelectedIndex = radio.TabIndex; 52 //} 53 //MessageDialog dlg = new MessageDialog("click." + SelectedIndex); 54 //var t = dlg.ShowAsync(); 55 }); 56 57 public void RadioImageButton_Checked(object sender, RoutedEventArgs e) 58 { 59 //RadioImageButton radio = e.OriginalSource as RadioImageButton; 60 //if (radio.IsChecked.Value) 61 //{ 62 // SelectedIndex = radio.TabIndex; 63 //} 64 //MessageDialog dlg = new MessageDialog("click." + SelectedIndex); 65 //var t = dlg.ShowAsync(); 66 } 67 } 68 }
RadioImageButtonConverter 代码
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 using Windows.UI.Xaml.Data; 7 8 namespace Demo.UWP.Converters 9 { 10 public class RadioImageButtonConverter : IValueConverter 11 { 12 public object Convert(object value, Type targetType, object parameter, string language) 13 { 14 if (string.Equals(value + "", parameter + "")) 15 { 16 return true; 17 } 18 else 19 return false; 20 } 21 22 public object ConvertBack(object value, Type targetType, object parameter, string language) 23 { 24 return Int32.Parse(parameter.ToString()); 25 } 26 } 27 }
搞定！再配合微软提供的ToolKit.UWP就可以愉快的写项目了
