AlarmManager触发的PendingIntent太快第二次 [英] AlarmManager triggers PendingIntent too soon for the second time
本文介绍了AlarmManager触发的PendingIntent太快第二次的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有这样的code:
设定报警:
public void setAlarm()
{
Calendar Calendar_Object = Calendar.getInstance();
Calendar_Object.add (Calendar.DAY_OF_YEAR, 1);
Calendar_Object.set(Calendar.HOUR_OF_DAY, 0);
Calendar_Object.set(Calendar.MINUTE, 0);
Calendar_Object.set(Calendar.SECOND, 1);
Intent myIntent = new Intent(Main.this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(Main.this,
0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC, Calendar_Object.getTimeInMillis(),1000*60*60*24, pendingIntent);
}
广播接收器:
public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent myIntent = new Intent(context, NotificationService.class);
context.startService(myIntent);
}
}
该服务:
public class NotificationService extends Service {
private NotificationManager mManager;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
}
@SuppressWarnings("deprecation")
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
mManager = (NotificationManager) this.getApplicationContext()
.getSystemService( this.getApplicationContext().NOTIFICATION_SERVICE);
Intent intent1 = new Intent(this.getApplicationContext(), ABC.class);
Notification notification = new Notification(R.drawable.ic_launcher,
"xxx", System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP
| Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(
this.getApplicationContext(), 0, intent1,
PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.setLatestEventInfo(this.getApplicationContext(),
"abc", "xyz",
pendingNotificationIntent);
mManager.notify(0, notification);
}
}
在00:00:01一切设置报警后是完美的,但下一次问题发生。所述的PendingIntent触发像间隔24小时之间6至8倍。我不记得如果时间为每个触发相同的,但我希望它每天一次。什么是错的code?
after setting the alarm at 00:00:01 everything is perfect but the next time the problem is happening. the PendingIntent triggers like 6 to 8 times between the 24 hours interval. I don't remember if the time is the same for each trigger but I want it one time each day. What is wrong with the code?
推荐答案
这将创建一个报警,每天将关闭在00:05,最重要的部分是 AlarmManager.INTERVAL_DAY
This will create an alarm that will go off every day at 00:05, the important part is the AlarmManager.INTERVAL_DAY
Date date = new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.set(Calendar.HOUR_OF_DAY, 0);
cal.set(Calendar.MINUTE, 5);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
cal.add(Calendar.HOUR, 24);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
mgr.cancel(pi);
mgr.setRepeating(AlarmManager.RTC, cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);
另外,不要忘记随时取消previous类似的报警,当重新设置一个新的,否则他们都会熄灭,古老的集报警,而新的,见上 mgr.cancel(PI);
