Notification

Android提供了Notification功能用于通知事件。 最常见的就是StatusBar上的使用。

使用例子

        //取得服务管理器
	private NotificationManager mNotyMgr;
         mNotyMgr = (NotificationManager)this.getSystemService(NOTIFICATION_SERVICE);
 
        //调用这个函数来发出notify
        //id为一个icon图标，text为第一次上bar通知时候提示的信息
         //下拉列表中的通知在myNotify.setLatestEventInfo函数中设置
         //通知的唯一性由NotificationManager.notify()的第一个参数确定，本例为notifyIndex
        //DnNotifyActivity为上bar下拉选中notify时启动的activity
	public void setNotify(int id,String text)
	{
		Intent notifyIntent = new Intent(this,DnNotifyActivity.class);
		notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
 
		PendingIntent appIntent = PendingIntent.getActivity(this, 0, notifyIntent, 0);
 
		Notification myNotify = new Notification();
		myNotify.icon = id;
		myNotify.tickerText = text;
		myNotify.defaults = Notification.DEFAULT_SOUND;
 
		myNotify.setLatestEventInfo(this, "Notify通知", "Notify按钮被按下了", appIntent);
		mNotyMgr.notify(notifyIndex,myNotify);
		notifyIndex++;
	}

        Toast.makeText(this, "这是在Notify调用的Activity中显示的Toast", Toast.LENGTH_SHORT).show();

		finish();
	}
