滚动不';t停止,同时通过在UWP中的投掷动作后点击屏幕来停止滚动动作
我尝试了下面的方法,同时将父StackPanel(VisualContainer)和子StackPanel(Items)上的操纵模式作为操纵模式进行处理。但我面临的问题是滚动没有停止,而停止滚动动作后触摸屏幕。我使用下面的代码 问题:在UWP中执行投掷动作后,触摸屏幕时滚动未停止 对于子StackPanel(Items)操作模式,它可以作为系统正常工作。但不在子StackPanel(Items)操作模式下工作 注意:我必须使用子堆栈面板(项目)操作模式作为所有模式。 这里我附上了示例代码片段 MainPage.xaml滚动不';t停止,同时通过在UWP中的投掷动作后点击屏幕来停止滚动动作,uwp,Uwp,我尝试了下面的方法,同时将父StackPanel(VisualContainer)和子StackPanel(Items)上的操纵模式作为操纵模式进行处理。但我面临的问题是滚动没有停止,而停止滚动动作后触摸屏幕。我使用下面的代码 问题:在UWP中执行投掷动作后,触摸屏幕时滚动未停止 对于子StackPanel(Items)操作模式,它可以作为系统正常工作。但不在子StackPanel(Items)操作模式下工作 注意:我必须使用子堆栈面板(项目)操作模式作为所有模式。 这里我附上了示例代码片段 M

如果(Math.Abs(y),启动fling后按下poniter后,可以通过处理VisualContainer的操纵增量事件来停止滚动,如下所示
bool isPointerPressed = false;
private void VisualContainer_PointerPressed(object sender, PointerRoutedEventArgs e)
{
isPointerPressed = true;
Debug.WriteLine("PointerPressed: " + ScrollViewer.VerticalOffset);
}
private void VisualContainer_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e)
{
if(!e.IsInertial)
{
isPointerPressed = false;
}
else if(isPointerPressed)
{
e.Complete();
return;
}
var offset = ScrollViewer.VerticalOffset - e.Delta.Translation.Y;
ScrollViewer.ChangeView(0, offset, null, true);
}
我已经处理了基于isPointerPressed变量的操作。还通过检查操作事件参数的ISenetial来确定指针在触发后被按下。启动触发后按下poniter后,可以通过处理VisualContainer的操纵增量事件来停止滚动,如下所示
