But how exactly is the behavior of each individual option? And what is the difference between Fill and the suffix Expand?
Theory The structure LayoutOptions controls two distinct behaviors: How is the view aligned within the parent view?
For vertical alignment the view is moved to the top. For horizontal alignment this is usually the left-hand side. But note, that on devices with right-to-left language setting this is the other way around, i. The view is centered. Usually the view is bottom or right aligned.
On right-to-left languages, of course, it is left aligned. This alignment is slightly different. The view will stretch across the full size of the parent view. Alignment only matters for parent views with additional space available.
Will the element occupy more space if available? If the parent view is larger than the combined size of all its children, i. Again, if the parent view is not larger than its children, the expansion suffix does not make any difference as well.
Example To demonstrate the effect of different LayoutOptions, we create a tiny example app. It consists of a gray StackLayout with some padding and some spacing between its child elements. Note that we use a device-dependent padding for the MainPage to avoid elements being overlaid by the iOS status bar.
Its text is centered horizontally and vertically using the two properties HorizontalTextAlignment and VerticalTextAlignment. Furthermore, it adds a flat yellow BoxView. This will serve as a visual separator between the space occupied by the white labels.
We make the following observations: The different alignment is only visible if there is space available.
If the stackLayout would not fill the page, we might not be able to see a difference between elements with options Start or StartAndExpand.
Additional space is evenly proportioned amongst all labels with Expand suffix. To see this more clearly we added yellow horizontal lines — actually flat BoxViews — between every two neighboring labels. In this case the actual behavior is controlled by their alignment.
The most obvious advantage is the imposed separation of layout and business logic. Furthermore, the XAML code might be shorter and more readable. On the other hand, there are some drawbacks. Thus, the layout description spreads across two files and two languages, which increases the complexity of our project structure.
And since most of the XAML is only parsed at run-time, the code-completion, syntax-highlighting and source code analysis is incomplete and sometimes misleading. Since nearly all features of Xamarin. Forms can be implemented using C only, we restrict ourselves to C within this book.
In the following, we want to give a tiny example on how to create an app using Xamarin and an XAML layout description. Given a blank Xamarin. This generates two files: The actual page content is framed by a ContentPage tag. Within this page we place a centered StackLayout with one Label and one Button.
Besides corresponding Text attributes we assign names. This will allow us to refer to these two elements from C code. The constructor calls a method InitializeComponent, which is implemented in a different part of the class definition.
The MainPage is now initialized with a new LabelPage.letter: A property that will hold the letter assigned to the tile.
isMatched: A property that will hold a Boolean indicating whether this tile has already been successfully “matched” to a target on the top of the screen. —Letter-Writing Tutorial.
