在 Android Studio 中设置多个警报

Question

I cannot seem to find an answer to this question, have been searching everywhere.

I am trying to manage two separate notifications in my project. I have a notification that send to the user when a bill is due, and a notification that is sent when a payment is successful.

When I call the notification from my AlarmReceiver class, the payment notification is called, even for the bill is due notification. I think this is because it is called last in the OnReceive, and so this cancels out the bill is due notification.

Is there a type of if or switch statement that I can put in my OnReceive, to see check which request code has been called (101 or 102) and then call that notification?

Here is my code:

public class AlarmReceiver extends BroadcastReceiver {

    private static final String CHANNEL_ID = "bills.channelId";


    /**
     * @param context
     * @param intent
     */
    @Override
    public void onReceive(Context context, Intent intent) {

        // run notification 1
        userHasBill(context, intent);
        // run notification 2
        userPaymentIsSuccessful(context, intent);


    }

    /**
     * Notification to call when the user sets a reminder
     * @param intent
     */
    public void userHasBill(Context context, Intent intent) {

        Intent notificationIntent = new Intent(context, MainMenuActivity.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(EmailActivity.class);
        stackBuilder.addNextIntent(notificationIntent);

        PendingIntent pendingIntent = stackBuilder.getPendingIntent(101, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification.Builder builder = new Notification.Builder(context);

        // Notification Builder and setting parameters?
        Notification notification = builder.setContentTitle("Bill Reminder!")
                .setContentText("Just a reminder that you have a bill due!")
                .setTicker("Just a reminder that you have a bill due!")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pendingIntent).build();


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            builder.setChannelId(CHANNEL_ID);
        }

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(
                    CHANNEL_ID,
                    "bills",
                    IMPORTANCE_DEFAULT
            );
            notificationManager.createNotificationChannel(channel);
        }

        notificationManager.notify(1, notification);


    }


    /**
     * Notification to call when bill payment is successful
     *
     * @param context current context
     * @param intent  intent to go to home activity
     */
    public void userPaymentIsSuccessful(Context context, Intent intent) {

        Intent notificationIntent = new Intent(context, MainMenuActivity.class);

        TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
        stackBuilder.addParentStack(EmailActivity.class);
        stackBuilder.addNextIntent(notificationIntent);

        PendingIntent pendingIntent = stackBuilder.getPendingIntent(102, PendingIntent.FLAG_UPDATE_CURRENT);

        Notification.Builder builder = new Notification.Builder(context);

        Notification notification = builder.setContentTitle("Payment successful!")
                .setContentText("Your payment was successful!")
                .setTicker("Your Payment was Successful!")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(pendingIntent).build();


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            builder.setChannelId(CHANNEL_ID);
        }

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(
                    CHANNEL_ID,
                    "bills",
                    IMPORTANCE_DEFAULT
            );
            notificationManager.createNotificationChannel(channel);
        }

        notificationManager.notify(1, notification);


    }


}

I already tried to make two channel IDs, but it still calls the second notification that's in the OnReceive

Answer 1

You need to use a unique notification id. Currently you are using the same id for both notifications:

notificationManager.notify(1, notification);

See also "Show the notification" from the guide on notifications

Is there a type of if or switch statement that I can put in my OnReceive, to see check which request code has been called (101 or 102) and then call that notification?

The AlarmReceiver is triggered by some other component. This component can put some flag as extra to the Intent which is used for the broadcast. Then you can evaluate the Intent extra in onReceive()
