如何在android中的应用程序图标上显示徽章计数？ ShortcutBadger 不起作用，我不想使用小部件

Question

I used ShortcutBadger library for android but it is not working in my case. I tested it on various devices. I googled about it and possible solution can be use of widget. Is there any other solution? Apps like facebook whatsapp showing the badge count and that is visible in my phone.

Answer 1

you could generate the local notification with custom count.
example :

Android Doc

Kotlin :

var notification = NotificationCompat.Builder(this@MainActivity, CHANNEL_ID)
        .setContentTitle("New Messages")
        .setContentText("You've received 3 new messages.")
        .setSmallIcon(R.drawable.ic_notify_status)
        .setNumber(3)
        .build()

Java:

Notification notification = new NotificationCompat.Builder(MainActivity.this, CHANNEL_ID)
        .setContentTitle("New Messages")
        .setContentText("You've received 3 new messages.")
        .setSmallIcon(R.drawable.ic_notify_status)
        .setNumber(3)
        .build();

following will trigger the notification.

NotificationManager notificationManager = (NotificationManager) getContext().getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(1, notificationBuilder.build());
