Android通知 - 显示完整消息

Question

我的Android应用程序必须能够向一大群人发送简短的警报.显而易见的地方是通知中心.完整通知显示在自动收报机中没有问题,但在通知中心,用户只能看到前几个单词,然后是省略号.通知不长,最多只有10-15个字.如何将文本换行到新行？

我在这里构建通知的代码

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
    .setSmallIcon(R.drawable.splash)
    .setContentTitle("Student Engauge")
    .setContentText(extras.getString("message"))
    .setAutoCancel(true)
    .setTicker(extras.getString("message"));
    final int notificationId = 1;
    NotificationManager nm = (NotificationManager) getApplicationContext()
          .getSystemService(Context.NOTIFICATION_SERVICE);
    nm.notify(notificationId, mBuilder.build());

要显示大块文本,请使用BigTextStyle.以下是BigTextStyle中给出的示例代码.此通知将包含一行文本,并在需要时将扩展为更多行.

Notification noti = new Notification.Builder()
 .setContentTitle("New mail from " + sender.toString())
 .setContentText(subject)
 .setSmallIcon(R.drawable.new_mail)
 .setLargeIcon(aBitmap)
 .setStyle(new Notification.BigTextStyle()
     .bigText(aVeryLongString))
 .build();

对于android支持库

Notification noti = new Notification.Builder()
 .setContentTitle("New mail from " + sender.toString())
 .setContentText(subject)
 .setSmallIcon(R.drawable.new_mail)
 .setLargeIcon(aBitmap)
 .setStyle(new NotificationCompat.BigTextStyle()
     .bigText(aVeryLongString))
 .build();
