android - 为什么不显示android通知文本？

Question

我编写了以下通知代码，我可以看到通知和通知标题，但文本不可见。我用静态值尝试了很多次，但仍然没有得到什么问题。请帮助我，在此先感谢。

private void messagenotification(String msg, String nextid) {


    SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.putString("id", nextid  ).apply();

    Intent intent = new Intent(this, NextActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setSmallIcon(R.mipmap.blue)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.blue))
            .setContentTitle("Chat")
            .setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);



    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}

似乎您在 notificationBuilder 上忘记了 .setContentText("Example")
