一、第一種比較實用

                                //點擊通知時轉移內容
                                m_Intent = new Intent(Activity01.this, Activity02.class);
                                //主要是設置點擊通知時顯示內容的類
                                m_PendingIntent = PendingIntent.getActivity(Activity01.this, 0, m_Intent, 0);                           
                                //設置通知在狀態欄顯示的圖標
				m_Notification.icon = R.drawable.img1;
				//當我們點擊通知時顯示的內容
				m_Notification.tickerText = "Button1通知內容...........";
				//通知時發出默認的聲音
				m_Notification.defaults = Notification.DEFAULT_SOUND;
				//設置通知顯示的參數
				m_Notification.setLatestEventInfo(Activity01.this, "Button1", "Button1通知", m_PendingIntent);
				//可以理解爲執行這個通知
				m_NotificationManager.notify(0, m_Notification);

通知欄伴有音效提示，顯示圖標，Button1通知內容...................,下拉通知欄時，顯示APP的ICON及標題Button1，內容 Button1通知。點擊通知內容時跳轉到另一個Activity

Pendingintent，一般用在 Notification上，可以理解爲延遲執行的intent，PendingIntent是對Intent一個包裝。
