Question

如何在向 ListView 添加新项目时禁用动画？

How to set animations/transitions when adding elements to a ListViews?

我试过这个例子，但它没有为我的列表显示任何列表页脚。

我试过这样做:

    <ListView>
        <ListView.ItemContainerTransitions>
            <ContentThemeTransition />  <!-- omit AddDeleteThemeTransition -->

        </ListView.ItemContainerTransitions>
    </ListView>

但这并没有运行，当我启动应用程序时它崩溃了。

documentation for ItemsControl.ItemContainerTransitions property 中指出了这个怪癖:

Important The XAML syntax for properties that have a TransitionCollection value is unusual in that you must declare an explicit TransitionCollection object element as the value, and then provide object elements as child elements of TransitionCollection for each of the transition animations you want to use. For most other XAML collection properties you could omit the collection object element because it can be implicit, but TransitionCollection doesn't support the implicit collection usage.

试试这个 XAML:

<ListView>
    <ListView.ItemContainerTransitions>
        <TransitionCollection>
            <ContentThemeTransition />  <!-- You can even omit this transition if desired -->
        </TransitionCollection>
    </ListView.ItemContainerTransitions>
</ListView>
