Question

我正在根据用户的时间显示通知，当我启动应用时，它始终显示通知，即使在取消后也会一直重复，这是不正确的

我没有在.setWhen

上设置按时显示通知

MainActivity.java

calendar=Calendar.getInstance();
day=calendar.get(Calendar.DAY_OF_MONTH);
month=(calendar.get(Calendar.MONTH));
year=calendar.get(Calendar.YEAR);

cLoader=new CursorLoader(this, BirthdayProvider.CONTENT_URI, null, BirthdayProvider.EVENT_DATE+"='"+day+"' and "+BirthdayProvider.EVENT_MONTH+"='"+month+"'", null, null);
c=cLoader.loadInBackground();
c.moveToFirst();
while (c.moveToNext()) {

calendar.set(Calendar.MONTH, (month-1));
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.DAY_OF_MONTH, day);

calendar.set(Calendar.HOUR_OF_DAY,19);//set the alarm time
calendar.set(Calendar.MINUTE, 06);
calendar.set(Calendar.SECOND,0);
long calMillis=calendar.getTimeInMillis();
int systemTimeID=(int)System.currentTimeMillis();   


Intent myIntent = new Intent(getBaseContext(), MyReceiver.class);
pendingIntent = PendingIntent.getBroadcast(MainActivity.this, systemTimeID, myIntent,0);             
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, calMillis, pendingIntent);

MyReceiver.java

public void onReceive(Context context, Intent intent) {
        // TODO Auto-generated method stub
        Toast.makeText(context.getApplicationContext(), "MyReceiver started", Toast.LENGTH_SHORT).show();       
        Intent service1 = new Intent(context, MyAlarmService.class);        
        context.startService(service1);
    }

MyAlarmService.java

public void onCreate() 
    {
       // TODO Auto-generated method stub  
       super.onCreate();
       calendar=Calendar.getInstance();
        date=calendar.get(Calendar.DAY_OF_MONTH);
        month=(calendar.get(Calendar.MONTH)+1);
        year=calendar.get(Calendar.YEAR);

          cLoader=new CursorLoader(this, BirthdayProvider.CONTENT_URI, null, BirthdayProvider.EVENT_DATE+"='"+date+"' and "+BirthdayProvider.EVENT_MONTH+"='"+month+"'", null, null);
        c=cLoader.loadInBackground();
      Toast.makeText(getBaseContext(), "My service started ", Toast.LENGTH_SHORT).show();
    }

public void onStart(Intent intent, int startId)
   {
       super.onStart(intent, startId);

       /*int count=intent.getIntExtra("count", 0);
       nameArray=intent.getStringArrayListExtra("name");
       numberArray=intent.getStringArrayListExtra("number");*/



    while (c.moveToNext()) {
        calendar.set(Calendar.MONTH,(month-1) ); 
        calendar.set(Calendar.YEAR, year); 
        calendar.set(Calendar.DAY_OF_MONTH, date); 

        calendar.set(Calendar.HOUR_OF_DAY, 5);
        calendar.set(Calendar.MINUTE, 19); 
        calendar.set(Calendar.SECOND, 0); 
        calendar.set(Calendar.AM_PM,Calendar.PM);

        count=count+1;





        mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);

        Intent intent1 = new Intent(this.getApplicationContext(),SearchListActivity.class);        
        intent1.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        intent1.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);

        PendingIntent pendingNotificationIntent = PendingIntent.getActivity( this.getApplicationContext(),0, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
        Uri uri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


        RemoteViews remoteView=new RemoteViews(getPackageName(), R.layout.normal_status_bar);
        remoteView.setTextViewText(R.id.title_name, name);


        Notification.Builder builder = new Notification.Builder(this);
        builder.setContentIntent(pendingNotificationIntent)
        .setContent(remoteView)
        .setSmallIcon(R.drawable.app_icon)
        .setLargeIcon(bitmapImage)
        .setTicker("Today's Events")
        .setWhen(calendar.getTimeInMillis())
        .setAutoCancel(true)
        .setContentTitle(name)
        .setVibrate(new long[] {0, 200, 200, 600, 600})
        .setNumber(count)
        .setSound(uri)
        .setLights(Color.BLUE, 1000, 1000)
        .setContentText("[ Event type : "+eventype+" ]\n\n"+"[ Turns : "+turns+" ]");
        Notification notification = builder.build(); 
        mManager.notify(count, notification);


    }

    }

问题在于month value set。不要减去它calendar.get(Calendar.MONTH)将给出正确的月份索引。

    while (c.moveToNext()) {
    calendar.set(Calendar.MONTH,(month) );

所以当你minus成为previous month时（不是你期望的当月）。月值从0开始。这就是启动应用程序时立即触发警报的原因（因为警报已经过去）

正如评论中所说 - setWhen只是一个时间戳，在通知发生时显示。这并不意味着需要在

时间设置的时间显示通知

.set当通知无法正常android
