FadeToAsync(VisualElement, Double, UInt32, Easing)

Source:: ViewExtensions.cs

Source:: ViewExtensions.cs

返回一个任务，它执行 opacity、length 和 easing 参数描述的淡化。

public static System.Threading.Tasks.Task<bool> FadeToAsync(this Microsoft.Maui.Controls.VisualElement view, double opacity, uint length = 250, Microsoft.Maui.Easing? easing = default);

static member FadeToAsync : Microsoft.Maui.Controls.VisualElement * double * uint32 * Microsoft.Maui.Easing -> System.Threading.Tasks.Task<bool>

<Extension()>
Public Function FadeToAsync (view As VisualElement, opacity As Double, Optional length As UInteger = 250, Optional easing As Easing = Nothing) As Task(Of Boolean)

参数

view: VisualElement

此方法操作的视图。

opacity: Double

要淡入的不透明度。

length: UInt32

动画转换的时间（以毫秒为单位）。默认值为 250。

easing: Easing

用于动画的缓动函数。

Task<Boolean>

一 Task 个包含一个 Boolean 值，该值指示动画是否已取消。 true 指示已取消动画。 false 指示动画已运行到完成。

例外

ArgumentNullException

当为 view时null引发。
