如何在 Android 中设置多个闹钟?

到目前为止,多亏了这个网站,我已经能够设置一个闹钟,即使我关闭手机,该闹钟也会设置并激活。

现在,我设置了一个警报来显示事件 A 的提醒,并且我需要应用程序设置另一个警报来显示事件 B 的另一个提醒。

我一定做错了什么,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相同的。 :-(

以下是我分两步执行的详细信息:

1) 从一项活动中,我设置了一个闹钟,该闹钟将在特定时间和日期呼叫接收器

                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) 从接收器中,我调用一项服务

        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);

So far and thanks to this website, I've been able to set up an alarm that will be set up and active, even if I turn of my phone.

Now, I set up a alarm to show a reminder for event A and I need the application to setup another alarm to show another reminder for event B.

I must be doing something wrong, because it only fires the reminder for event A. It seems that once set up, any other alarm is understood as the same one. :-(

Here is the detail of what I am doing in two steps:

1) From an activity I set an alarm that at certain time and date will call a receiver

                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) From the receiver I call a service

        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);

Thanks in Advance,

好的,当您设置 PendingIntent 时,您应该为其分配一个唯一的 ID,以防您稍后想要识别它(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,而不是每次使用不同的 RequestCode。

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

它必须是一个整数,我假设您有一个primaryid(itemId)可以识别警报A和警报B。

Ok, when you set an PendingIntent, you're supposed to assign it a unique ID to it, incase you want to identify it later (for modifying/canceling it)

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().

The Request code is that ID.

In your code, you keep resetting the SAME PendingIntent, instead use a different RequestCode each time.

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

It has to be an integer, i suppose you have a primaryid (itemId) that can identify Alarm A from Alarm B.

您可以通过在pendingIntent.getBroadcast(……)中提供不同的请求代码来设置多个警报。

我用来设置多个警报的方法是创建一个警报。我在警报设置类中初始化了一个静态整数,每当我在主要活动中单击“添加警报”按钮时,该整数就会从主要活动中递增。
例如

MainActivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void addAlarmClick(View v) {
    AlarmActivity.broadcastCode++;
    startActivity(new Intent(this, AlarmActivity.class));
}
}

AlarmActivity.java

public class AlarmActivity extends AppCompatActivity {`
//........
public static int broadcastCode=0;
//........
Intent myIntent = new Intent(AlarmActivity.this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(AlarmActivity.this,
                            broadcastCode, myIntent, 0);

You can set up multiple alarms by supplying different request code in pendingIntent.getBroadcast(......)

The approach which I used to setup multiple alarm is that I created a single alarm. I initialized a static integer in alarm setting class which will be incremented each time from my main activity whenever I click on "add alarm" button in my main activity.
E.g.

MainActivity.java

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

public void addAlarmClick(View v) {
    AlarmActivity.broadcastCode++;
    startActivity(new Intent(this, AlarmActivity.class));
}
}

AlarmActivity.java

public class AlarmActivity extends AppCompatActivity {`
//........
public static int broadcastCode=0;
//........
Intent myIntent = new Intent(AlarmActivity.this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(AlarmActivity.this,
                            broadcastCode, myIntent, 0);

为了更简单的方法,如果您通过 RecyclerView 列出警报,

PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), recyclerAdapterAlarm.getItemCount()+1, intent, PendingIntent.FLAG_UPDATE_CURRENT);

它对我有用。

For an easier way, if you are listing your Alarms by RecyclerView,

PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), recyclerAdapterAlarm.getItemCount()+1, intent, PendingIntent.FLAG_UPDATE_CURRENT);

It works for me.
