触摸设备中的 AvaloniaUI 重复按钮

如何解决触摸设备中的 AvaloniaUI 重复按钮

我正在尝试使用 AvaloniaUI 为适用于 Linux 的触摸设备构建的应用程序中的按钮修复一个问题。

我对现有按钮的问题是：当用户用手指触摸按钮并按住时，事件在用户按住按钮的同时重复发生，这不是所需的行为。我想强制用户每次想要触发事件时都触摸按钮。

我不确定这种触摸处理是否可用。这是我的代码： XAML：

... 
<Button Name="btnIncrement" Content="Increment" />
<Label Name="lblCount" />
...

C# 代码：

...
btn = this.FindName<Button>("btnIncrement");
lbl = this.FindName<Label>("lblCount");
...
private void btnClick(object sernder,RoutedEventArgs e)
{
   lblCount.Content = ++Counter;
}

更新以下是当我将手指放在按钮（通常是屏幕）上时命令 evtest 的输出，我也可以看到在屏幕上重复单击按钮的效果。
