Xamarin Views and Controls

In Xamarin, Views and Controls are used to define the user interface of mobile applications. Views contain layout and UI elements, while Controls are the UI elements responsible for user interaction and data input. Xamarin provides a wide range of Views and Controls that developers can use to create mobile applications.

Syntax

<View>
    <Control/>
    <Layout>
        <Control/>
    </Layout>
</View>

Example

The following example shows how to create a simple mobile application in Xamarin using Views and Controls.

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MyApp.MainPage">

    <StackLayout>
        <Label Text="Welcome to MyApp!"
               FontSize="Large"
               VerticalOptions="CenterAndExpand" 
               HorizontalOptions="CenterAndExpand" />

        <Entry Placeholder="Enter your name" />

        <Button Text="Submit"
                Clicked="OnSubmitButtonClicked" />
    </StackLayout>

</ContentPage>

In this example, we've used three Controls, Label, Entry, and Button, within a StackLayout. The Label displays a welcome message, the Entry is used to get user input, and the Button triggers an event when clicked.

Explanation

Views are the building blocks of the user interface in Xamarin. They represent the layout containers and UI elements that users interact with. Controls, on the other hand, are the UI elements that the user interacts with and provides the input data.

Xamarin provides a wide range of Views and Controls that developers can use to create rich and interactive user interfaces. Views such as Frame, ScrollView, StackLayout, and AbsoluteLayout, and Controls such as Button, Image, Entry, and Label, etc., can be used to create a wide variety of UI designs.

Use

Views and Controls are used to define the user interface of mobile applications. They are commonly used to design layout structures, display text, images, and other media, receive user input, and create interactive elements such as buttons, switches, and sliders.
