.setWhen(System.currentTimeMillis())

是在推送通知android中设置时间的代码，结果类似于15.54。但是，如果我想用秒时间设置这个15:54:02的时间，我该怎么办？你能帮帮我或提供示例源代码吗？

这是我的通知管理器源代码。

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(mCtx);
    Notification notification;
    notification = mBuilder.setSmallIcon(R.drawable.logo).setTicker(title).setWhen(0)
            .setAutoCancel(true)
            .setContentIntent(resultPendingIntent)
            .setContentTitle(title)
            .setSmallIcon(R.drawable.logo)
            .setWhen(System.currentTimeMillis())
            .setLargeIcon(BitmapFactory.decodeResource(mCtx.getResources(), R.mipmap.ic_launcher))
            .setContentText(message)
            .build();

    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.flags |= Notification.FLAG_SHOW_LIGHTS;

    notification.defaults = Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    notification.defaults = Notification.DEFAULT_ALL;
    int id = (int) System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) mCtx.getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(ID_SMALL_NOTIFICATION, notification);
    notificationManager.notify(id, notification);
}

但如果我想像这样设定时间15:54:02

内置通知布局无法实现这一点。如果您真的需要秒，则需要自定义通知布局。但我强烈反对这一点。

你设置或不设置毫秒.setWhen（）默认情况下它会得到。

时间格式您希望显示的内容如15:54:02 24小时格式与秒。时间格式NotificationCompat.Builder类没有设置。

您设置转换为时间的毫秒数，以便在15:54这样的通知中显示，而不是秒。

您可以使用自定义通知视图，而不是默认视图。

    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
    String formattedDate = "";
    formattedDate = sdf.format(new Date());

    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);
    contentView.setImageViewResource(R.id.image, R.drawable.logo);
    contentView.setTextViewText(R.id.title, title);
    contentView.setTextViewText(R.id.text, message);
    contentView.setTextViewText(R.id.time, formattedDate);

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.home)
            .setContent(contentView);

    Notification notification = mBuilder.build();
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.defaults |= Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_VIBRATE;
    NotificationManager notificationManager = (NotificationManager) MainActivity.this.getSystemService(Context.NOTIFICATION_SERVICE);
    int id = (int) System.currentTimeMillis();
    notificationManager.notify(id, notification);

布局..

像这样输出......

Answer 3

为此，您需要以毫秒为单位转换时间“14:54:02”并将结果时间设置为.setWhen()

Answer 4

SimpleDateFormat formatter = new SimpleDateFormat("hh:mm:ss"); 

String dateString = formatter.format(new Date(dateInMillis)));

如何在第二次设置通知的时间和日期？
