android两种定时器实现

一、定时循环执行

private static Handler handler = new Handler();

private static Runnable runnable = new Runnable(new Action(run));

private static void run()

{

//renwushow.PostInvalidate();//刷新内容

handler.PostDelayed(runnable, 1000 * 3);

}

注意：在当前页面销毁时停止执行的活动

/// <summary>

/// activity销毁

/// </summary>

protected override void OnDestroy()

{

handler.RemoveCallbacks(runnable); //停止刷新

base.OnDestroy();

}

二、定时执行一次

public class mytimetask : TimerTask

{

public override void Run()

{

//要执行的活动，例如等待页面加载完成后执行相应的操作

}

}

Java.Util.Timer timer = new Java.Util.Timer();

timer.Schedule(new mytimetask(), 1000);
