Pivot的Header花式效果

要实现如上图所示的效果分为三步：

1.重写Pivot样式，去掉Pivot的Header或者是直接使用默认的Pivot的样式然后不写Header

2.使用一个ListView或者是横向的StackPanel或者是横向的Grid加上一个Button代替Header的效果（我使用的是Grid，建议使用ListView）

3.在Pivot的SelelctionChanged事件中以及当做Header的Button的Click事件做一个同步

首先Pivot的Item你想放什么就放什么

然后就是代替Header的问题：我用的Grid套了5个Button

 1 <Grid Grid.Row="0" x:Name="TopBar" Background="#FDF187">
 2             <Grid.ColumnDefinitions>
 3                 <ColumnDefinition Width="*"/>
 4                 <ColumnDefinition Width="*"/>
 5                 <ColumnDefinition Width="2*"/>
 6                 <ColumnDefinition Width="2*"/>
 7                 <ColumnDefinition Width="*"/>
 8             </Grid.ColumnDefinitions>
 9             <Button x:Name="Header0" Style="{StaticResource GrayLightButton}"
10                     Background="Transparent" Grid.Column="0" Content="设置" FontFamily="Segoe MDL2 Assets,Segoe UI"
11                     FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Header0_Click"/>
12             <Button x:Name="Header1" Style="{StaticResource GrayLightButton}"
13                     Background="Transparent" Grid.Column="1" Content="鸣谢" FontFamily="Segoe MDL2 Assets,Segoe UI"
14                     FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Header1_Click"/>
15             <Button x:Name="Header2" Style="{StaticResource GrayLightButton}"
16                     Background="Transparent" Grid.Column="2" Content="开源与引用" FontFamily="Segoe MDL2 Assets,Segoe UI"
17                     FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Header2_Click"/>
18             <Button x:Name="Header3" Style="{StaticResource GrayLightButton}"
19                     Background="Transparent" Grid.Column="3" Content="更新记录" FontFamily="Segoe MDL2 Assets,Segoe UI"
20                     FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Header3_Click"/>
21             <Button x:Name="Header4" Style="{StaticResource GrayLightButton}"
22                     Background="Transparent" Grid.Column="4" Content="关于" FontFamily="Segoe MDL2 Assets,Segoe UI"
23                     FontSize="15" HorizontalAlignment="Center" VerticalAlignment="Center" Click="Header4_Click"/>
24         </Grid>

最后就是在后台代码中实现PivotItem与Grid的同步：

Pivot的SelelctionChanged事件实现Button的文字和颜色切换

 1 private void Pivot_SelectionChanged(object sender, SelectionChangedEventArgs e)
 2         {
 3             Header0.Content = "设置";
 4             Header0.FontSize = 15;
 5             Header0.Foreground = new SolidColorBrush(Color.FromArgb(225, 128, 128, 128));
 6             Header1.Content = "鸣谢";
 7             Header1.FontSize = 15;
 8             Header1.Foreground = new SolidColorBrush(Color.FromArgb(225, 128, 128, 128));
 9             Header2.Content = "开源与引用";
10             Header2.FontSize = 15;
11             Header2.Foreground = new SolidColorBrush(Color.FromArgb(225, 128, 128, 128));
12             Header3.Content = "更新记录";
13             Header3.FontSize = 15;
14             Header3.Foreground = new SolidColorBrush(Color.FromArgb(225, 128, 128, 128));
15             Header4.Content = "关于";
16             Header4.FontSize = 15;
17             Header4.Foreground = new SolidColorBrush(Color.FromArgb(225, 128, 128, 128));
18             switch (pivot.SelectedIndex)
19             {
20                 case 0:
21                     Header0.Content = "";//Segoe MDL2 Assets图标
22                     Header0.FontSize = 25;
23                     Header0.Foreground = new SolidColorBrush(Color.FromArgb(225, 0, 122, 204));
24                     break;
25                 case 1:
26                     Header1.Content = "";//Segoe MDL2 Assets图标
27                     Header1.FontSize = 25;
28                     Header1.Foreground = new SolidColorBrush(Color.FromArgb(225, 0, 122, 204));
29                     break;
30                 case 2:
31                     Header2.Content = "";//Segoe MDL2 Assets图标
32                     Header2.FontSize = 25;
33                     Header2.Foreground = new SolidColorBrush(Color.FromArgb(225, 0, 122, 204));
34                     break;
35                 case 3:
36                     Header3.Content = "";//Segoe MDL2 Assets图标
37                     Header3.FontSize = 25;
38                     Header3.Foreground = new SolidColorBrush(Color.FromArgb(225, 0, 122, 204));
39                     break;
40                 case 4:
41                     Header4.Content = "?";//Segoe MDL2 Assets图标
42                     Header4.FontSize = 25;
43                     Header4.Foreground = new SolidColorBrush(Color.FromArgb(225, 0, 122, 204));
44                     break;
45             }
46         }

然后就是点击Button实现PivotItem的切换

以第一个Button举个栗子，以此类推

1         private void Header0_Click(object sender, RoutedEventArgs e)
2         {
3             pivot.SelectedIndex = 0;
4             pivot.SelectedItem = pivot.Items[0];
5         }

就这样就可以实现如上效果了。

还可以做一个扩展：在Grid中Button下面加一扁扁的矩形，然后后台代码处理矩形的隐藏和出现，可以实现更加好看的效果。
