C# 表单如何禁用ListView上的单击动画
我目前开发了一个使用ListView的应用程序。 这个应用程序是用Xamarin.Forms创建的，最初用于Android和iOS。然而，我们也决定准备一个UWP项目 问题是，当单击listview中的项目时，UWP应用程序中会出现单击动画： 看这张图，我所说的动画是什么意思： 然而，这个动画在我们的项目中看起来并不好 问题是： 如何禁用listview项目上的单击动画？ 我们只想成为一个没有任何动画的listview。只是一个简单的平面列表，同时保留EventHandler 在另一个Stackoverflow论坛上，他们告诉我们禁用控件。但这使得控件完全无用，因为我们无法获取selecteditem+它禁用了滚动 我还发现了这个有用的论坛，但此说明适用于UAP（Win8应用程序）：C# 表单如何禁用ListView上的单击动画,c#,listview,xamarin.forms,C#,Listview,Xamarin.forms,我目前开发了一个使用ListView的应用程序。 这个应用程序是用Xamarin.Forms创建的，最初用于Android和iOS。然而，我们也决定准备一个UWP项目 问题是，当单击listview中的项目时，UWP应用程序中会出现单击动画： 看这张图，我所说的动画是什么意思： 然而，这个动画在我们的项目中看起来并不好 问题是： 如何禁用listview项目上的单击动画？ 我们只想成为一个没有任何动画的listview。只是一个简单的平面列表，同时保留EventHandler 在另一个Stac
有人可以分享一个如何禁用动画的示例或示例代码吗？我认为您可以通过使用自定义渲染器来实现这一点。但是，另一个选项是利用包“”，其中有一个名为FlowTappedBackgroundColor的属性，您可以通过该属性在点击时将单元格的背景色设置为“透明”。使用自定义渲染器。如果转到UWP项目的一部分，并将控件用作Windows.UI.Xaml.Controls.ListView，则有一个属性IsItemClickEnabled，您需要创建自定义列表视图渲染器并对其应用自定义样式 创建派生的ListView：
