我正在尝试在不同的特定时间重复多个警报。问题是警报接收器在任何给定时间都没有被调用。

我在活动中的代码：

private void setAlarms() {
    Intent myIntent=new Intent(this, AlarmReceiver.class);
    myIntent.putExtra("MedName",medication_name);
    myIntent.setAction("b5.project.medibro.receivers.AlarmReceiver");
    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    //am.set(AlarmManager.RTC_WAKEUP, time, pendingIntent);
    ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();
    int counter=0;
    for(String timer: timers){
       //timers is an array of Strings in the format hh:mm
         try {
            String[] comps=timer.split(":");
            Calendar cal=Calendar.getInstance();
            cal.set(Calendar.HOUR_OF_DAY, Integer.valueOf(comps[0]));
            cal.set(Calendar.MINUTE, Integer.valueOf(comps[1]));
            cal.set(Calendar.SECOND, 0);
            cal.set(Calendar.MILLISECOND, 0);
            Log.d(TAG,comps[0]+" "+comps[1]+ "Alarm Time: " + cal.getTime().toString());
            PendingIntent pendingIntent = PendingIntent.getService(this, counter, myIntent,0);
            am.setInexactRepeating(AlarmManager.RTC_WAKEUP,
                    cal.getTimeInMillis(),
                    AlarmManager.INTERVAL_DAY,
                    pendingIntent);
            counter++;
        } catch (ParseException e) {
            e.printStackTrace();
            Log.d(TAG,"Time Parsing error: "+e.getMessage());
        }
    }
}

这是我的警报接收器：

public class AlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getAction().equals("b5.project.medibro.receivers.AlarmReceiver")) {
        Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
        Log.d("Alarm Receiver", "Alarm is invoked. ");

        NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
        builder.setSmallIcon(R.drawable.messenger_bubble_large_blue);
        builder.setContentTitle("Time to take your medicine");
        String medName = intent.getStringExtra("MedName");
        String text = "Medicine name: " + medName;
        builder.setContentText(text);

        Notification notification = builder.build();
        NotificationManagerCompat.from(context).notify(0, notification);
        Toast.makeText(context, "I'm running", Toast.LENGTH_SHORT).show();
    }
}

}

清单声明：（在应用程序标签内）

<receiver android:name="b5.project.medibro.receivers.AlarmReceiver"
        android:enabled="true">
        <intent-filter>
            <action android:name="b5.project.medibro.receivers.AlarmReceiver"/>
        </intent-filter>
    </receiver>

我觉得上面的代码应该至少执行一次广播接收器，但 logcat 中没有显示任何内容。有人能告诉我我错过了什么吗？

而不是 getService 尝试 getBroadcast：

PendingIntent pendingIntent = PendingIntent.getService(this, counter, myIntent,0);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, counter, myIntent,0);

另请查看http://developer.android.com/reference/android/app/PendingIntent.html#getBroadcast(android.content.Context , int, android.content.Intent, int)，并找出您需要的标志，因为如果只有最后一个警报（在 for 循环中）起作用，我不会感到惊讶。
