Adding the View
Create a new folder named Views
into the MvvmCrossDemo.Forms.UI
project to store the views. Add a new Xamarin.Forms Content Page item called FirstView.xaml
into the View folder to correspond the FirstViewModel.cs
in the MvvmCrossDemo.Core
project so that we can reuse the ViewModel
layer.
Xamarin.Forms
uses the XAML
language to describe the UI but bear in mind that there are slight differences between the Xamarin.Forms
XAML and the UWP XAML. For instance, we use TextBox
in UWP to represent a control that can receive the input from users, but in Xamarin.Forms, the control is called Entry
. For the Button
control, in UWP we use Content
property to show the text of the Button
, but in Xamarin.Forms
, the property is called Text
. It makes a little bit inconvenience but probably, they will be unified to XAML Standard
in the future. For more details, please check all the control definitions of Xamarin.Forms
here: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/.
Open the FirstView.xaml.cs
and make sure it is inherited from MvxContentPage
, as shown below:
Then open the FirstView.xaml
file and update the content like this:
Look, the file content contains similar controls with UWP, but has some different controls. We changed the base class of the FirstView
from ContentPage
to MvxContentPage
and added the references to views
, mvx
and viewModels
. Additionally, we need to specify the x:TypeArguments
as in the xaml file. The MvxContentPage
class in the FirstView.xaml.cs
also has a generic parameter as FirstViewModel
. So that we built the relationship between the FirstView
and the FirstViewModel
. The first UI is done!
