如何在Android中设置多个警报？

Question

到目前为止,由于这个网站,我已经能够设置一个即使我打开手机也会设置并激活的闹钟.

现在,我设置了一个警报,显示事件A的提示,我需要应用程序设置另一个警报,以显示事件B的另一个提醒.

我必须做错事,因为它只会触发事件A的提醒.似乎一旦设置,任何其他警报都被理解为同一个警报.:-(

以下是两步中我正在做的细节:

1)从一项活动中我设置了一个警报,在某个时间和日期将呼叫接收者

                Intent intent = new Intent(Activity_Reminder.this,
                        AlarmReceiver_SetOnService.class);

                intent.putExtra("item_name", prescription
                        .getItemName());
                intent
                        .putExtra(
                                "message",
                                Activity_Reminder.this
                                        .getString(R.string.notif_text));
                intent.putExtra("item_id", itemId);
                intent.putExtra("activityToTrigg",
                        "com.companyName.appName.main.Activity_Reminder");

                PendingIntent mAlarmSender;

                mAlarmSender = PendingIntent.getBroadcast(
                        Activity_Reminder.this, 0, intent, 0);

                long alarmTime = dateMgmt.getTimeForAlarm(pickedDate);
                Calendar c = Calendar.getInstance();
                c.setTimeInMillis(alarmTime);
                // Schedule the alarm!
                AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
                am.set(AlarmManager.RTC_WAKEUP, alarmTime + 15000,
                        mAlarmSender);

2)从接收器我呼叫服务

        Bundle bundle = intent.getExtras();
        String itemName = bundle.getString("item_name");
        String reminderOrAlarmMessage = bundle.getString("message");
        String activityToTrigg = bundle.getString("activityToTrigg");
        int itemId = Integer.parseInt(bundle.getString("item_id"));
        NotificationManager nm = (NotificationManager) context.getSystemService("notification");
        CharSequence text = itemName + " "+reminderOrAlarmMessage;
        Notification notification = new Notification(R.drawable.icon, text,
                System.currentTimeMillis());
        Intent newIntent = new Intent();
        newIntent.setAction(activityToTrigg);
        newIntent.putExtra("item_id", itemId);
        CharSequence text1= itemName + " "+reminderOrAlarmMessage;
        CharSequence text2= context.getString(R.string.notif_Go_To_Details);
        PendingIntent pIntent = PendingIntent.getActivity(context,0, newIntent, 0);
        notification.setLatestEventInfo(context, text1, text2, pIntent);
        notification.flags = Notification.FLAG_AUTO_CANCEL;
        notification.defaults = Notification.DEFAULT_ALL;
        nm.notify(itemId, notification);

好的,当您设置PendingIntent时,您应该为其分配一个唯一的ID,以便您稍后要识别它(用于修改/取消它)

static PendingIntent    getActivity(Context context, int requestCode, Intent intent, int flags) 
//Retrieve a PendingIntent that will start a new activity, like calling Context.startActivity(Intent).
static PendingIntent    getBroadcast(Context context, int requestCode, Intent intent, int flags) 
//Retrieve a PendingIntent that will perform a broadcast, like calling Context.sendBroadcast().

请求代码就是该ID.

在您的代码中,您不断重置SAME PendingIntent,而是每次使用不同的RequestCode.

PendingIntent pIntent = PendingIntent.getActivity(context,uniqueRQCODE, newIntent, 0);

它必须是一个整数,我想你有一个primaryid(itemId)可以从报警B识别报警A.
