运行每分钟服务

我有，我想执行任务的背景下每分钟的服务。它并不需要执行任务时的电话是睡着了，只有当用户主动使用它。我试图用它建立了一个IntentService做到这一点，如下所示：

I have a service that I am wanting to execute a task every minute in the background. It does not need to execute the task whenever the phone is asleep, only when the user is actively using it. I am trying to do this with an IntentService which is set up as follows:

public class CounterService extends IntentService{ public CounterService() { super("CounterService"); } @Override public int onStartCommand(Intent intent, int flags, int startId) { return super.onStartCommand(intent,flags,startId); } @Override protected void onHandleIntent(Intent intent) { Toast.makeText(this, "onhandleintent", Toast.LENGTH_SHORT).show(); while(true) { //one minute is 60*1000 try { Thread.sleep(5 * 1000); Toast.makeText(getApplicationContext(), "getting app count", Toast.LENGTH_LONG).show(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }

目前得到的功能性的工作，我只是希望它显示敬酒每5秒钟，我会在以后更改为一分钟。如果我有，而（真）注释掉，则显示onhandleintent的消息。但是，如果我有以下的code运行，无论是敬酒显示。我该如何解决这个问题？

Right now to get the functionality working I simply want it to display a toast every 5 seconds, I will change it to one minute later. If I have the while(true) commented out, then the "onhandleintent" message is displayed. However if I have the following code run, neither of the Toasts display. How can I fix this?

推荐答案

这将发送的意图，你的服务，每分钟不使用你的活动的任何处理器时间

This will send an intent to your service every minute without using any processor time in your activity in between

Intent myIntent = new Intent(context, MyServiceReceiver.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, myIntent, 0); AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(System.currentTimeMillis()); calendar.add(Calendar.SECOND, 60); // first time long frequency= 60 * 1000; // in ms alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), frequency, pendingIntent);

调整MyServiceReceiver.class来匹配你的目标服务或活动

adjust MyServiceReceiver.class to match your target service or activity
