如何在Xamarin中添加计时器? [英] How do I add a timer in Xamarin?

问题描述

所以我需要有一个计时器，从60秒开始倒计时.我是Xamarin的新手，也不知道它接受什么.它将在Android中使用.

So I need to have a timer to count down from 60 seconds. I am new to Xamarin and have no idea what it accepts. It will be used in Android.

关于如何开始的任何建议?

Any suggestions on how to start?

您可以使用 System.Timers.Timer 吗?

推荐答案

您可以使用System.Threading.Timer类，该类记录在Xamarin文档中:

You can use the System.Threading.Timer class, which is documented in the Xamarin docs: https://developer.xamarin.com/api/type/System.Threading.Timer/

或者，对于Xamarin.Forms，您可以通过Device类访问跨平台计时器:

Alternatively, for Xamarin.Forms, you have access to a cross-platform Timer via the Device class:

Device.StartTimer(TimeSpan.FromSeconds(1), () =>
{
    // called every 1 second
    // do stuff here

    return true; // return true to repeat counting, false to stop timer
});
