Android：多个警报不起作用

【中文标题】Android：多个警报不起作用【英文标题】：Android: Multiple Alarm not working 【发布时间】：2011-12-29 07:19:32 【问题描述】：在我的应用程序中，我设置了两个闹钟。 在上的工具按钮上，我将使用以下代码进行设置：
case R.id.toggleButtonTwoMonth:
myPrefs = this.getSharedPreferences("myPrefs",MODE_WORLD_WRITEABLE);
if (tButtonTwoMonth.isChecked())
Toast.makeText(getApplicationContext(), "Two months reminder is On", Toast.LENGTH_SHORT).show();
prefsEditor = myPrefs.edit(); prefsEditor.putBoolean("TwoMonth", true); prefsEditor.commit();
//For Broadcast Alarm
Intent in = new Intent(this, AlarmReceiverNotificationForTwoMonth.class);
alarmManagerForTwoMonth1 = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmManagerForTwoMonth2 = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
pendingIntentOfTwoMonth1 = PendingIntent.getBroadcast(this, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
pendingIntentOfTwoMonth2 = PendingIntent.getBroadcast(this, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
// ===================== GST ALARM FOR THE TWO MONTHS ==========================
// for the GST 20 June 2011
Calendar calendar_GST_18_June_2011 = Calendar.getInstance();
calendar_GST_18_June_2011.setTimeInMillis(System.currentTimeMillis());
calendar_GST_18_June_2011.set(2011, 5, 18, mHour, mMinute, 0);
alarmManagerForTwoMonth1.set(AlarmManager.RTC_WAKEUP, calendar_GST_18_June_2011.getTimeInMillis(), pendingIntentOfTwoMonth1);
// for the GST 17 August 2011
Calendar calendar_GST_17_August_2011 = Calendar.getInstance();
calendar_GST_17_August_2011.setTimeInMillis(System.currentTimeMillis());
calendar_GST_17_August_2011.set(2011, 7, 17,mHour, mMinute, 0);
alarmManagerForTwoMonth2.set(AlarmManager.RTC_WAKEUP, calendar_GST_17_August_2011.getTimeInMillis(),pendingIntentOfTwoMonth2);
else
Toast.makeText(getApplicationContext(), "Two months reminder is Off", Toast.LENGTH_SHORT).show();
prefsEditor = myPrefs.edit(); prefsEditor.putBoolean("TwoMonth", false); prefsEditor.commit();
//alarmManagerForTwoMonth.cancel(pendingIntentOfTwoMonth);
break;
但是我在那个希望的时间没有收到 amarm 通知，如果切换是打开的。 现在警报时间过去了，如果我关闭然后再打开，我就会收到警报。
那么我的代码有什么问题？ 请帮助我。

有了这个答案，我已经解决了多次设置警报：How can I setup multiple alarms in android?
但我想知道如何处理它。我的意思是如何使用不同的消息处理接收器上的警报？
我更新的带有多个警报的代码如下：
//For Broadcast Alarm
Intent in = new Intent(this, AlarmReceiverNotificationForTwoMonth.class);
// ===================== GST ALARM FOR THE TWO MONTHS ==========================
// for the GST 20 June 2011
alarmManagerForTwoMonth1 = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
pendingIntentOfTwoMonth1 = PendingIntent.getBroadcast(this, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar calendar_GST_18_June_2011 = Calendar.getInstance();
calendar_GST_18_June_2011.setTimeInMillis(System.currentTimeMillis());
calendar_GST_18_June_2011.set(2011, 5, 18, mHour, mMinute, 0);
alarmManagerForTwoMonth1.set(AlarmManager.RTC_WAKEUP, calendar_GST_18_June_2011.getTimeInMillis(), pendingIntentOfTwoMonth1);
// for the GST 17 August 2011
alarmManagerForTwoMonth2 = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
pendingIntentOfTwoMonth2 = PendingIntent.getBroadcast(this, 1, in, PendingIntent.FLAG_UPDATE_CURRENT);
Calendar calendar_GST_17_August_2011 = Calendar.getInstance();
calendar_GST_17_August_2011.setTimeInMillis(System.currentTimeMillis());
calendar_GST_17_August_2011.set(2011, 7, 17,mHour, mMinute, 0);
alarmManagerForTwoMonth2.set(AlarmManager.RTC_WAKEUP, calendar_GST_17_August_2011.getTimeInMillis(),pendingIntentOfTwoMonth2);
接收方的代码如下：
public void onReceive(Context context, Intent intent)
// TODO Auto-generated method stub
// My Notification Code
notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.app_icon;
CharSequence text = "Your tax amount due period";
CharSequence contentTitle = "Tax Calculator App";
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
System.out.println("the Date is: "+(cal.getTime().getDate())+" "+ (cal.getTime().getMonth())+" "+ (cal.get(Calendar.YEAR)));
if((cal.getTime().getDate()==18) && (cal.getTime().getMonth()==5) && (cal.get(Calendar.YEAR)==2011))
contentText = "Your GST tax amount is due on 20 June 2011";
else if((cal.getTime().getDate()==17) && (cal.getTime().getMonth()==7) && (cal.get(Calendar.YEAR)==2011))
contentText = "Your GST tax amount is due on 19th August, 2011";
else
contentText = "Your GST tax amount is due on Falana Dhikna Date";
long when = System.currentTimeMillis();
intent = new Intent(context, NotificationViewer.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
notification = new Notification(icon,text,when);
long[] vibrate = 0,100,200,300;
notification.vibrate = vibrate; // To vibrate the Device
notification.ledARGB = Color.RED;
notification.ledOffMS = 300;
notification.ledOnMS = 300;
notification.defaults |= Notification.DEFAULT_LIGHTS;
//notification.flags |= Notification.FLAG_SHOW_LIGHTS;
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notificationManager.notify(NotificationConstants.NOTIFICATION_ID, notification);
现在如何处理不同的警报？ 帮我解决这个问题。 谢谢。

现在。在这里我收到了通知。但我希望它为所有人分开。意味着如果已经存在一个并且如果生成了新的，那么它不应该更新已经存在的，而是应该创建新的单独的。 谢谢。
【问题讨论】：
您使用 sqlite 数据库（内部数据库）保存警报并使用广播接收器获取警报通知。 不，我没有为此使用任何数据库。 . .为什么 ？我应该这样做吗？ 请看我更新的问题。 【参考方案1】：好吧，你为什么不这样做
Intent in = new Intent(this, AlarmReceiverNotificationForTwoMonth.class);
in.putExtra("MyMessage","Your tax is due on blah blah blah");
pendingIntentOfTwoMonth1 = PendingIntent.getBroadcast(this, 0, in, PendingIntent.FLAG_UPDATE_CURRENT);
而在onRecieve
只需从 Intent 中检索消息
public void onReceive(Context context, Intent intent)
// blah blah
Toast.show(context,intent.getStringExtra("MyMessage"),Toast.LENGTH_LONG).show();
【讨论】：
好的，如果我将它用于我的代码，那么它会按我的意愿工作吗？ 是的，设置闹钟时，使用意图来存储有关事件的数据...在您的广播接收器中，只需从该意图中检索数据（onRecieve 的第二个参数）它是相同的您在设置闹钟时创建的一个
我在意图未解析变量时遇到语法错误
是的，您的代码运行良好。现在，如果我不想更新警报通知并获得自己的每个通知怎么办。我的意思是现在如果已经有任何通知并且如果我收到另一个通知，那么新通知将更新过去的通知。因此，如果我想为所有人单独通知，那我该怎么办？
@iDroidExplorer，对每一个使用不同的requestCode，看到PendingIntent.getBroadcast()调用中的0参数？对于每个不同的警报，这应该是不同的。【参考方案2】：
请使用数据库从以下链接尝试我的答案。
AlarmManager with Broadcast Receiver
首先从您的活动中将闹钟时间和日期添加到数据库中，然后创建广播接收器类以从数据库中获取数据。
【讨论】：
所以如果我想为选择日期制作多个警报，那么我必须使用数据库来使用所选日期？ 但是如果我使用带有选定日期和时间的 Single Alatm 那么它可以工作，那么为什么其他日期不工作呢？ 在内置警报中，如果您使用数据库进行多个警报，从上面的链接为我工作，那么单个警报是有效的。 我只想在不同的日期制作不同的 Alam。 . .有了这个，我可以得到它。 ***.com/questions/3273342/… 我必须为接下来的 17 天设置闹钟，每天设置 4 次。使用单个方法调用同时设置多个警报不起作用，但是通过对未决意图第二个参数使用唯一 id 对我来说效果很好。谢谢。请在这里查看***.com/questions/44858366/…以上是关于Android：多个警报不起作用的主要内容，如果未能解决你的问题，请参考以下文章
