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，因此我可以判断它们是否正在成功执行（每个活动/服务每10秒运行一次）。
当我点击“确定”启动这两项服务时 - 我看到了我的第一项服务的祝酒 - 但第二项服务从未出现过 - 之后没有任何反应。
非常感谢任何建议/意见！
AlarmManager警报服务：
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);
AlarmManager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);
}
