C# 如何在停止/播放动画中的特定位置启动progressbar？[沙马林表格]

这就是我用来阻止progressbar正常工作的方法

progressBar.Animate("SetProgress", (arg) => {

     System.Diagnostics.Debug.WriteLine(arg); // 0.00 - 1.00 is the value
     progressBar.Progress = arg;

}, 1, 5000, Easing.Linear, 
(v, c) => progressBar.Progress = 0);  // when finished, reset

因此，每次制作动画时，progressbar都从0开始。现在我想从某个时间开始。比如说，从500毫秒5秒中的第二个3秒开始

然后我这样做，progressBar.Progress=0.3；在动画上方。无论哪种方式，progressbar仍然从0秒开始

如何在设定的5秒时间内启动计时器？

尝试这样设置动画的初始值

progressBar.AbortAnimation("SetProgress");

取消

var animation = new Animation (v => progressBar.Progress = v, 0.3, 1);

animation.Commit (this, "SimpleAnimation", 16, 2000, Easing.Linear, (v, c) => image.Scale = 1, () => false);

可以使用自定义动画：

this.AbortAnimation ("SimpleAnimation");

如何停止此动画？

double totalTime = 5000;
double startTime = 3000;
var animation = new Animation(v => progress.Progress = v, startTime/totalTime, 1, Easing.Linear);
animation.Commit(this, "LinearProgressFromTime", 16, (uint)(totalTime - startTime) , Easing.Linear, (v, c) => progress.Progress = 1, () => false);
