            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
            builder.setContentTitle("这是通知的title..");
            builder.setContentText("这是内容文本....");
            builder.setSmallIcon(R.drawable.ic_launcher);// 小图片
