C#使用Xamarin开发(1)

很早就尝试了移动开发,曾用Android studio学习了一下. 

一直没有开发的动能. vs2017开始直接可以Xamarin进行移动开发,开始尝试一下.

什么是Xamarin?Xamarin

From Wikipedia, the free encyclopedia

Xamarin is a Microsoft-owned  San Francisco, California-based software company founded in May 2011 ^[3] by the engineers that created  Mono, ^[4]  Mono for Android and  MonoTouch, which are  cross-platform implementations of the  Common Language Infrastructure (CLI) and Common Language Specifications (often called Microsoft .NET).

With a C#-shared codebase, developers can use Xamarin tools to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms, including Windows and macOS.^[5]According to Xamarin, over 1.4 million developers were using Xamarin's products in 120 countries around the world as of April 2017.^[6]

On February 24, 2016, Microsoft announced it had signed a definitive agreement to acquire Xamarin.^[7]

^{Hello world!}

.Hellow world

按Vs2017導引,順利創建一個空白Andriod項目,在畫面放入一個Button

在 MainActivity創建時:

Button helloButton = FindViewById<Button>(Resource.Id.buttonHello);
helloButton.Click += delegate { Toast.MakeText(this, "Procedimento de logon ", ToastLength.Long).Show(); };

在設備管理中,增加一個模擬手機.第一次啟動與真機一樣慢.

启动后,在IIS的調試選項上看到这个ADV了

 

.发布至Android手机

我是華為手機,連到電腦,在設置中,打開關于手機,在型號處連擊五下,進入開發者模式.

在設置中,打開開發者選項,打開調試模式.

電腦順利認到,還是相當方便

重新打開iis,在調試選項上看到世界名牌華為了.click 运行.手机正常下载安装.

太棒了
