仅显示小通知,如应用程序锁定或标题部分

我想通知你 . 为此尝试了不同的代码。

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this,
            "AppLock007")
            .setSmallIcon(R.drawable.ic_lock)
            .setColor(Color.TRANSPARENT)
            .setContentTitle("App Lock")
            .setContentText("Securing your apps")
            .setOngoing(true)
            .setContentIntent(pendingIntent);

Notification notification = notificationBuilder.build();
