Using xamarin studio windows#
All the mobile development companies started using visual studio in both Windows and Mac, it is a great improvement after Microsoft acquired Xamarin.Įvery developer and company should be very clear, Microsoft isn’t throwing away Xamarin. Microsoft then integrated Xamarin into Visual Studio. In 2016, Xamarin was acquired by Microsoft, after that Xamarin was open source and removed payment options. On May 16, 2011, Miguel de Icaza announced on his blog that Mono would be developed and supported by Xamarin. Let’s go back a bit in time first, the name Xamarin comes from the name of the Tamarin monkey, replacing the leading T with an X. Let’s see the structure of the project:Inside the Resources folder you will add all your resources like images or storyboards (you are not going to use them in Xamarin.Forms).The AppDelegate file is the entry point of your iOS app: namespace Tutorial01.Xamarin was released 10 years before, it has helped many developers to develop mobile apps with multi-platform with native feel but now it’s time to say goodbye to Xamarin and happily welcome. NetStandard project.Usually you don’t have to edit this file unless you have to load external plugins or intercept events like OnActivityResult (when you launch another activity, after it terminates you’ll get the result here) or OnResume (when the app goes in foreground). Inside the method OnCreate we need to initialize Xamarin.Forms and load the. Protected override void OnCreate(Bundle bundle) Public class MainActivity : global:.FormsAppCompatActivity
Using xamarin studio android#
Let’s see the structure of the project:Inside the Resources folder you will add all your resources like images, styles and native layouts.MainActivity is the entry point of your Android app: namespace Tutorial01.Droid We see that MainPage inherits from a ContentPage (as the XAML file) and inside the constructor we need to call InitializeComponent to load the XAML file.Because the app does nothing, this file is basically empty otherwise here you can add the logic of your page (unless you want to follow an MVVM approach…I’ll add a link here as soon as the MVVM guide is ready). Public partial class MainPage : ContentPage
What we have here is a ContentPage and inside a single element, a Label with text (“Welcome to Xamarin.Forms!”) and alignment options, so where are saying that we want to show that text at the centre of the screen (we have seen it before).And this is the code-behind file: This is the page that will be displayed when we will launch the app. OnSleep and OnResume are called every time the app appears and goes in background.Now it’s time for the MainPage file. Inside the constructor we initialize the XAML file with “InitializeComponent()” and load the first page with “MainPage = new Tutorial01.MainPage() ”.As you have seen, MainPage is the actual page displayed on-screen, so every time we want to change a page, we need to assign a new value to MainPage (We’ll see that there are also other ways to do it).OnStart is called when the app is started. From this file Xamarin loads the first Page of the app and usually we initialize other parts of the project like Resources, Databases and so on.Now let’s see the structure of the code-behind file using Xamarin.Forms
Using xamarin studio code#
Here we write the UI and the logic and if our project it’s easy enough, we don’t need to write code in the other projects of our solution.Inside our project there are 2 file, App.xaml and MainPage.xaml. It’s here that we are going to write our app.
This is common project shared by all the other projects. The projects are already working so if we try to run one of the projects (Android, iOS, UWP) this is what we get:That’s brilliant, few second and we already have a working project for Android, iOS and UWP.Now it’s time to understand how a Xamarin.Forms project works so we are going now to analyze the projects we have in our solution.NET Standard NET Standard project (our common library, where we are going to write almost all our code), and Android project, an iOS project and a UWP project.
NET Standard.After we press ok, Visual Studio will take several seconds (or minutes according to your machine) to create your solution.Inside the Solution Explorer we see now that we have a. Under UI Technology select Xamarin.Forms and under “Code Sharing Strategy” choose. In this case I’ve chosen Android, iOS, Windows (UWP). Under Platform choose the platforms you need. In this case we start with a Blank app that is perfect to explain how a Xamarin.Forms solution works. From Visual Studio 2017 create a New project…Under “Visual C#” select “Cross-Platform” (1) then select “Cross-Platform App (Xamarin.Forms)” (2), choose name and location for your project (3) and press Ok (4).Now we need to configure our project.
