Xamarin表单ProgressBar停止 [英] Xamarin Forms ProgressBar Stop

问题描述

在Xamarin Forms中停止进度栏动画的最佳方法是什么?进展始于:

What is the best way to stop the progress bar animation in Xamarin Forms? Progress is started with:

animProgressBar = async () => { 
 ... 
 await progressBar.ProgressTo (0, 10000, Easing.Linear); 
 ... 
};

我想停止动画并重新启动它.我尝试过类似的事情

I would like to stop the animation and restart it. I have tried things like

progressBar.AbortAnimation("ProgressTo");

没有成功.

推荐答案

我不确定是否可以取消ProgressTo，我想创建自己的动画是最简单的解决方案:

I'm not sure that it is possible to cancel ProgressTo and I suppose that creating own animation is easiest solution:

new Button
{
    Text = "Kick progress bar",
    Command = new Command(() =>
    {
        if (progressBar.AnimationIsRunning("SetProgress"))
        {
            progressBar.AbortAnimation("SetProgress");
        }
        else
        {
            progressBar.Animate("SetProgress",(arg) => { progressBar.Progress = arg; }, 8*60, 8*1000, Easing.Linear);
        }
    })
}

结果:
