我有一个警报的工作实例 - 但是当我尝试创建第二个警报时 - 第一个和第二个意图都不会重复执行，我真的不确定为什么会发生这种情况。

我为每个活动/服务添加了一个 toast 用于测试目的，这样我就可以判断它们是否成功执行（每个活动/服务每 10 秒运行一次）。

当我单击“确定”启动这两项服务时——我看到了我的第一项服务的祝酒词——但第二项服务最初从未出现——之后什么也没有发生。

非常感谢任何建议/意见！

AlarmManager 报警服务：

        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.SECOND, 10);
        Intent intent = new Intent(Rules.this, LMW.class);
        PendingIntent pintent = PendingIntent.getService(Rules.this, 0, intent,
                0);
        AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                100000000 * 1000, pintent);

警报管理器活动：

      //  Calendar cal = Calendar.getInstance();
      //  cal.add(Calendar.SECOND, 10);
        Intent intent2 = new Intent(Rules.this, KillTimer.class);
        PendingIntent pintent2 = PendingIntent.getActivity(Rules.this, 0, intent2,
                0);
        AlarmManager alarm2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                30 * 1000, pintent2); // here    

    // click listener for the button to start service
    Button btnStart = (Button) findViewById(R.id.button1);
    btnStart.setOnClickListener(new View.OnClickListener() {

更改第二个警报中的 PendingIntent。而不是 pintent 使用 pintent2。 

Calendar cal = Calendar.getInstance();
    cal.add(Calendar.SECOND, 10);
    Intent intent = new Intent(Rules.this, LMW.class);
    PendingIntent pintent = PendingIntent.getService(Rules.this, 0, intent,
            0);
    AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
            100000000 * 1000, pintent);


    // Start 2nd service using AlarmManager

  //  Calendar cal = Calendar.getInstance();
  //  cal.add(Calendar.SECOND, 10);
    Intent intent2 = new Intent(Rules.this, KillTimer.class);
    PendingIntent pintent2 = PendingIntent.getActivity(Rules.this, 1, intent2,
            0);
    AlarmManager alarm2 = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
            30 * 1000, pintent2); // here

请尝试使用此代码。

// context variable contains your `Context`
AlarmManager mgrAlarm = (AlarmManager) context.getSystemService(ALARM_SERVICE);
ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();

for(i = 0; i < 10; ++i)
{
   Intent intent = new Intent(context, OnAlarmReceiver.class);
   // Loop counter `i` is used as a `requestCode`
   PendingIntent pendingIntent = PendingIntent.getBroadcast(context, i, intent, 0);
   // Single alarms in 1, 2, ..., 10 minutes (in `i` minutes)
   mgrAlarm.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 
                SystemClock.elapsedRealtime() + 60000 * i, 
                pendingIntent); 

   intentArray.add(pendingIntent);
}
