无法判断是否已安排闹钟 - 重复闹钟

Question

我有一个在 StartActivity 类中启动的重复警报。包是 psychsoft.gps.v1 代码似乎没有捕捉到警报是否启动。

        if ((PendingIntent.getBroadcast(con, 13336,
            new Intent("psychsoft.gps.v1"), 
            PendingIntent.FLAG_NO_CREATE) != null))
    {
        Log.i("aaa", "Alarm is already active");
        Toast.makeText(con, "alarm already active", Toast.LENGTH_SHORT).show();
    }



    Calendar calGPS = Calendar.getInstance();
    Intent intentGPS = new Intent(con, AlarmReceiver.class);
    intentGPS.putExtra("alarm_message", "gps");
    PendingIntent senderGPS = PendingIntent.getBroadcast(this, 13336, intentGPS, PendingIntent.FLAG_UPDATE_CURRENT);        
    // Get the AlarmManager service
    AlarmManager amGPS = (AlarmManager) getSystemService(ALARM_SERVICE);
    amGPS.setRepeating(AlarmManager.RTC_WAKEUP, calGPS.getTimeInMillis(),1000*60*5, senderGPS);

为了测试这段代码，我运行它一次来安排警报（安装应用程序）。然后我再次运行它（通过单击图标）以尝试获取 Toast 或 Log 输出。我都没有。为什么？我原本以为可以通过将 PendingIntent 的请求代码与 if 语句的请求代码匹配来解决问题，但它并没有解决问题。

尝试像这样创建和检查意图：

Intent intentGPS = new Intent("psychsoft.gps.v1.MY_UNIQUE_ACTION");

和

if ((PendingIntent.getBroadcast(con, 13336,
            new Intent("psychsoft.gps.v1.MY_UNIQUE_ACTION"), 
            PendingIntent.FLAG_NO_CREATE) != null))
    {
        Log.i("aaa", "Alarm is already active");
        Toast.makeText(con, "alarm already active", Toast.LENGTH_SHORT).show();
    }
