NotificationCompat.MessagingStyle

public static class NotificationCompat.MessagingStyle
extends NotificationCompat.Style

java.lang.Object
   ↳ android.support.v4.app.NotificationCompat.Style
     ↳ android.support.v4.app.NotificationCompat.MessagingStyle


Helper class for generating large-format notifications that include multiple back-and-forth messages of varying types between any number of people.
If the platform does not provide large-format notifications, this method has no effect. The user will always see the normal notification view.
This class is a "rebuilder": It attaches to a Builder object and modifies its behavior, like so:


 Notification noti = new Notification.Builder()
     .setContentTitle("2 new messages wtih " + sender.toString())
     .setContentText(subject)
     .setSmallIcon(R.drawable.new_message)
     .setLargeIcon(aBitmap)
     .setStyle(new Notification.MessagingStyle(resources.getString(R.string.reply_name))
         .addMessage(messages[0].getText(), messages[0].getTime(), messages[0].getSender())
         .addMessage(messages[1].getText(), messages[1].getTime(), messages[1].getSender()))
     .build();
