在Xamarin中的Timer中设置时间间隔

Question

在我的Xamarin应用程序中，我想设置计时器的计时器间隔，例如5秒后启动并运行10秒。

这是我的代码示例

Device.StartTimer(TimeSpan.FromSeconds(5), () =>
{
FaceIdentityInstruction = "Look Down";
return false;
});

Answer 1

您可以在Device.StartTimer5秒后添加System.Timers。

private static System.Timers.Timer aTimer;
static int count = 0;
public PageListView()
{
InitializeComponent();
Console.WriteLine("Timer prepare for running");
Device.StartTimer(TimeSpan.FromSeconds(5), () =>
{
Console.WriteLine("Timer run");
aTimer = new System.Timers.Timer(1000);
// Hook up the Elapsed event for the timer. 
aTimer.Elapsed += OnTimedEvent;
aTimer.AutoReset = true;
aTimer.Enabled = true;
return false;
});
}

private static void OnTimedEvent(Object source, ElapsedEventArgs e)
{
count++;
if (count==10)
{
aTimer.Stop();
Console.WriteLine("Timer Stop");
}
}

输出：

10-23 10:34:14.250 I/mono-stdout(29128): Timer prepare for running
10-23 10:34:19.262 I/mono-stdout(29128): Timer run
10-23 10:34:29.286 I/mono-stdout(29128): Timer Stop
