AlarmManager setRepeating()

Question

我的程序旨在创建一个重复警报,触发广播接收者依次发出通知.使用用户输入的间隔重复警报.

例如,如果我想将警报设置为每10秒运行一次,我该怎么做？

 am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),  10000, calpendingintent);

这是正确的吗？我的广播接收器由于某种原因没有被调用.

public static void createAlarms(Context mcontext) {
    cal = Calendar.getInstance();
    cal.add(Calendar.HOUR, alarmintervalint);
    calintent = new Intent(mcontext, AlarmBroadcastReceiver.class);
    calpendingintent = PendingIntent.getBroadcast(mcontext.getApplicationContext(), 12345, calintent, 0);
    am = (AlarmManager)mcontext.getSystemService(Activity.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),  10000, calpendingintent);
}

我的broadcastreceiver类没有被调用,我不确定我使用的"setRepeating()"方法设置是否正确..

请帮忙!

使用此代码

  AlarmManager alarmMgr;
  PendingIntent pendingIntent;

    public void startAlarmManager()
        {
             Intent dialogIntent = new Intent(getBaseContext(), AlarmBroadcastReceiver.class);

                  alarmMgr = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
                  pendingIntent = PendingIntent.getBroadcast(this, 0, dialogIntent,PendingIntent.FLAG_CANCEL_CURRENT);

                  alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(), 10000, pendingIntent);

              }
        }

你想要停止报警

public void stopAlarmManager()
{          
    if(alarmMgr != null)
       alarmMgr.cancel(pendingIntent);
}

记住不要忘记在清单文件中注册Receiver

  <receiver android:name=".AlarmBroadcastReceiver" >
        </receiver>

你可以用这个。希望它能解决您的问题

am.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
    SystemClock.elapsedRealtime() + AlarmManager.INTERVAL_DAY,
    AlarmManager.INTERVAL_DAY, pi);
