gmail在Android中使用哪种通知类型

Question

What type of notification does Gmail use in Nexus4 (Android 4.3) ?

It has two special features I would like to use as well.

a) When there are multiple mails to read all their headers appear one after the other. and a bottom line is drawn.

b) When there is no space in the notification page, the Gmail notification shrinks and sums all headers to on line.

How do they do this? How can I do this as well?

Answer 1

It is basically the Big View and Notification.BigTextStyle .

You can either customize your layout or use it under default notification by:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("Title")
                .setStyle(new NotificationCompat.BigTextStyle().bigText("Message"))
                .setContentText("Message");   

For customizing layouts of your Notifications, which may be well suited depending on the requirement, refer:
