[Android] 通知(Notification)

Take a note !! so next time if i use notification it will become faster :")) 
新(New):Notification.Builder來快速產生出來

NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE );
Builder builder = new Notification.Builder(Update.this );
PendingIntent contentIndent = PendingIntent.getActivity(Update. this, 0, new Intent(Update.this , Update. class),PendingIntent. FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIndent)
       .setSmallIcon(R.drawable.icon) // 設置狀態列裡面的圖示　　　　　　　　　　
       .setTicker("New Message") // 設置狀態列的顯示的資訊
       .setWhen(System. currentTimeMillis()) // 設置發生時間
       .setContentTitle( "I-Calories計算結果通知" )//設置通知清單裡的標題
       .setContentText("共消耗"+ca); // 設置內容
							  
Notification notification = builder.getNotification();
notificationManager.notify(1, notification);

設定預設提示音(notification.defaults to set default alarm ring)

notification.defaults |= Notification.DEFAULT_SOUND;//預設鈴聲
