Android消息通知栏的实现方法介绍

//消息通知栏
        //定义NotificationManager
        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
        //定义通知栏展现的内容信息
        int icon = R.drawable.icon;
        CharSequence tickerText = "我的通知栏标题";
        long when = System.currentTimeMillis();
        Notification notification = new Notification(icon, tickerText, when);

        //定义下拉通知栏时要展现的内容信息
        Context context = getApplicationContext();
        CharSequence contentTitle = "我的通知栏标展开标题";
        CharSequence contentText = "我的通知栏展开详细内容";
        Intent notificationIntent = new Intent(this, BootStartDemo.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);
        notification.setLatestEventInfo(context, 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);
