android - 为什么我的通知没有出现

Question

大家好，我正在使用预先通知管理器，这是代码

Notification note = new Notification();
    RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notif);
    contentView.setImageViewResource(R.id.image, R.drawable.notif);
    contentView.setTextViewText(R.id.title, "Focused Crawling");
    contentView.setTextViewText(R.id.text, "Crawling In Progress....");
    note.contentView = contentView;

    Intent notificationIntent = new Intent(this, LoadingActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    note.contentIntent = contentIntent;
    note.vibrate = new long[] { 500L, 200L, 200L, 500L };
    note.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "2");
    note.flags |= Notification.FLAG_NO_CLEAR;

    mgr.notify(1337, note);
    startForeground(1337, note);

为什么它没有出现在状态栏上？

Answer 1

您没有为状态栏指定图标，这是必需的。 在您的代码中添加这样一行:

note.icon = R.drawable.youricon;
