        int icon = R.drawable.logo;
        long when = System.currentTimeMillis();
        Notification notification = new Notification(icon, tickerText, when);
        //CharSequence tickerText = "titile";
        //定义下拉通知栏时要展现的内容信息
        //CharSequence contentTitle = "intro_index";
        //CharSequence contentText = "intro";

        Intent notificationIntent = new Intent(myContext, VoiceIdentify.class);

        PendingIntent contentIntent = PendingIntent.getActivity(myContext, 0,notificationIntent, 0);

        notification.setLatestEventInfo(myContext, contentTitle, contentText,contentIntent);

        //用mNotificationManager的notify方法通知用户生成标题栏消息通知

        mNotificationManager.notify(1, notification);
