public static class NotificationCompat.MessagingStyle
extends NotificationCompat.Style

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

Helper类用于生成包含多个不同类型的多个来回消息的大格式通知。
如果平台不提供大幅面通知，则此方法不起作用。 用户将始终看到正常的通知视图。
这个类是一个“重建器”：它附着到一个Builder对象并修改它的行为，如下所示：


 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();
