我有winRT（Win phone 8.1）的程序应用程序，我使用FlipView控件如下：
<FlipView x:Name="flvMain" Margin="0,0,0,0" Background="Transparent" SelectedIndex="1" SelectionChanged="flvMain_SelectionChanged" Tapped="flvMain_Tap">
<!-- Flip View Item 1 -->
<Grid x:Name="grdOption" >
<Grid.RowDefinitions>
<RowDefinition Height="120"/>
<RowDefinition Height="50"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">

<ImageBrush Stretch="Fill" ImageSource="Assets/test1.png"/>
</Grid.Background>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="100"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="50"/>
</Grid.ColumnDefinitions>
<Image x:Name="imgAvatar" Grid.Column="0" Margin="10,15" Source="Assets/Logo.png"/>
<Grid Grid.Column="1" Margin="0,15">
<TextBlock x:Name="txbNameAlias" Margin="0,5,0,54" FontSize="22" FontWeight="Bold" SelectionHighlightColor="{x:Null}" Foreground="White" RequestedTheme="Light">Name</TextBlock>
<TextBlock x:Name="txbAccountId" Margin="0,36,0,0" FontSize="16" RequestedTheme="Light" Foreground="White" Height="20" VerticalAlignment="Top">55556666</TextBlock>
<TextBlock x:Name="txbAmount" Margin="0,61,0,0" FontSize="18" FontWeight="Bold" RequestedTheme="Light" Foreground="#FFFFFEFE">555555</TextBlock>
</Grid>
<Button x:Name="btnBackToMain" Grid.Column="2" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MinHeight="50" MinWidth="40" Margin="5,30" BorderBrush="Transparent" RenderTransformOrigin="0.54,-0.035" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" Click="btnBackToMain_Click">

<!-- Flip View Item 2 -->

<Image x:Name="btnToListFunction" Grid.Column="0" Source="Assets/icon-menu.png" Margin="7" Tapped="btnToListFunction_Tap"></Image>
</Grid>
<ScrollViewer Grid.Row="1" HorizontalAlignment="Stretch" VerticalAlignment="Top">
<StackPanel Background="White">
<!-- some code here -->
</StackPanel>
</ScrollViewer>
</Grid>
</FlipView>
在 XAML 中.cs文件中我有代码
protected override void OnNavigatedTo(NavigationEventArgs e)
{
flvMain.SelectedIndex = 1;
}
它运行正常，但是当我单击btnBackToMain并点击btnToListFunction时，我有代码：
private void btnBackToMain_Click(object sender, RoutedEventArgs e)
{
flvMain.SelectedIndex = 1;
}
private void btnToListFunction_Tap(object sender, TappedRoutedEventArgs e)
{
flvMain.SelectedIndex = 0;
}
FlipView 无法将项目更改为特殊索引。当我通过选择更改事件调试单击事件时
private void flvMain_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (flvMain != null)
{
CustomTool.Log(this, "current index: " + flvMain.SelectedIndex);
}
else
{
CustomTool.Log(this, "NULLL");
}
}
我有点击 btnToListFunction 的结果：
Log: MainPage >> current index: 0
Log: MainPage >> current index: 1
并单击 btn返回主页
Log: MainPage >> current index: 1
Log: MainPage >> current index: 0
但是当我向右滑动（同样点击btnBackToMain）时，我得到的结果：
Log: MainPage >> current index: 1
并向左滑动（同样单击 btnToListFunction ） 我有结果：
Log: MainPage >> current index: 0
请帮我解决吗？我不知道为什么翻转视图的选定索引可以在更改（通过单击）后回滚。感谢大家的支持！
我有一个类似的问题，不同之处在于我的按钮是AppBarButton。如果您使用鼠标单击按钮，它将正常工作;因此，我猜问题是由操纵启动的某些事件引起的。我通过声明来解决这个问题
ManipulationMode="None"
对于翻转视图中的按钮。
因此，您可以通过将ManipulationMode="None"嵌入到 XAML 中的 btnBackToMain 和btnToListFunction 元素中来解决此问题。
希望此解决方案对您有所帮助。

如果不想将"操作"设置为"无"以忽略按钮上的所有操作，则可以尝试在将flvMain.SelectedIndex设置为所需数字之前设置flvMain.SelectedIndex = -1;。例如
private void btnBackToMain_Click(object sender, RoutedEventArgs e)
{
flvMain.SelectedIndex = -1;
flvMain.SelectedIndex = 1;
}
private void btnToListFunction_Tap(object sender, TappedRoutedEventArgs e)
{
flvMain.SelectedIndex = -1;
flvMain.SelectedIndex = 0;
}
因为问题仅在原始索引成功时发生，并且 -1 可用于 SelectedIndex 而不选择任何内容。
为什么FlipView的行为是这样的？我不知道。也许当人们把手指放在它上面时，它可以避免不稳定的行为。^_^
