Remarks
Application developers can control the placement of child elements by providing proportional coordinates, device coordinates, or a combination of both, depending on the AbsoluteLayoutFlags values that are passed to SetLayoutFlags(BindableObject, AbsoluteLayoutFlags) method. When one of the proportional AbsoluteLayoutFlags enumeration values is provided, the corresponding X, or Y arguments that range between 0.0 and 1.0 will always cause the child to be displayed completely on screen. That is, you do not need to subtract or add the height or width of a child in order to display it flush with the left, right, top, or bottom of the AbsoluteLayout. For width, height, X, or Y values that are not specified proportionally, application developers use device-dependent units to locate and size the child element.
The following example shows how to use an AbsoluteLayout with proportional position arguments.
Label header = new Label
{
Text = "AbsoluteLayout Demo",
FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label)),
HorizontalOptions = LayoutOptions.Center
};
AbsoluteLayout simpleLayout = new AbsoluteLayout
{
BackgroundColor = Color.Blue.WithLuminosity(0.9),
VerticalOptions = LayoutOptions.FillAndExpand
};
topLeftLabel = new Label
{
Text = "Top Left",
TextColor = Color.Black
};
centerLabel = new Label
{
Text = "Centered",
TextColor = Color.Black
};
bottomRightLabel = new Label
{
Text = "Bottom Right",
TextColor = Color.Black
};
// PositionProportional flag maps the range (0.0, 1.0) to
// the range "flush [left|top]" to "flush [right|bottom]"
AbsoluteLayout.SetLayoutFlags(bottomRightLabel,
AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(topLeftLabel,
new Rectangle(0f,
0f, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));
AbsoluteLayout.SetLayoutFlags(centerLabel,
AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(centerLabel,
new Rectangle(0.5,
0.5, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));
AbsoluteLayout.SetLayoutFlags(bottomRightLabel,
AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(bottomRightLabel,
new Rectangle(1f,
1f, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));
simpleLayout.Children.Add(topLeftLabel);
simpleLayout.Children.Add(centerLabel);
simpleLayout.Children.Add(bottomRightLabel);
The code sample below shows how to place two labels by specifying device-dependent units.
AbsoluteLayout simpleLayout = new AbsoluteLayout
{
BackgroundColor = Color.Blue.WithLuminosity(0.9),
VerticalOptions = LayoutOptions.FillAndExpand
};
Label header = new Label
{
Text = "Device Units Demo",
TextColor = Color.Black,
FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label))
};
topLeftText = new Label
{
Text = "Left",
TextColor = Color.Black
};
AbsoluteLayout.SetLayoutFlags(topLeftText,
AbsoluteLayoutFlags.None);
AbsoluteLayout.SetLayoutBounds(topLeftText,
new Rectangle(0f, 0f, 100f, 50f));
middleText = new Label
{
Text = "Device-dependent location",
TextColor = Color.Black
};
AbsoluteLayout.SetLayoutFlags(middleText,
AbsoluteLayoutFlags.None);
AbsoluteLayout.SetLayoutBounds(middleText,
new Rectangle(100f, 200f, 200f, 50f));
simpleLayout.Children.Add(topLeftText);
simpleLayout.Children.Add(middleText);
}
XAML for Microsoft.Maui.Controls supports the following attached properties for the AbsoluteLayout class:
Attached Property | Value |
---|---|
AbsoluteLayout.LayoutBounds | A comma-separated list—possibly with spaces—of four values that specify the bounding rectangle's position and dimensions. The first two values in the list must represent numbers. The latter two values may each either be numbers, or the string "AutoSize". The |
AbsoluteLayout.LayoutFlags | AbsoluteLayoutFlags enumeration value names: |
Application developers can use XAML to lay out elements with the AbsoluteLayout class. The example below places a blue BoxView inside an AbsoluteLayout:
<AbsoluteLayout VerticalOptions="FillAndExpand"
HorizontalOptions="FillAndExpand">
<BoxView AbsoluteLayout.LayoutBounds="0.25, 0.25, 0.5, 0.5"
Color="Blue"
AbsoluteLayout.LayoutFlags="All" />
</AbsoluteLayout>
The AbsoluteLayout class can lay its child elements out in proportional units, device units, or a combination of both. Application developers should remember the following points when specifying a Rectangle structure that will define the layout bounds of a child element:
- For elements whose height and width fit on the screen, proportional position dimensions in the range [0,1] represent elements that are completely on the screen, regardless of whether the height, width, or both are specified in device or proportional units.:
- The above point means that, to specify an element in the lower right hand corner of the screen and that is half as wide and half as all as the screen, with a AbsoluteLayoutFlags value of
All
, the application developer would specify "1.0, 1.0, 0.5, 0.5".: - The app developer can inadvertently cause child elements for which one or both size dimensions were specified proportionally to be displayed partially off the screen, or hidden altogether, by specifying device-unit positions that do not leave enough room for the calculated size of the child.:
- Each part of the bounding Rectangle structure is interpreted according to the AbsoluteLayoutFlags value that controls it. A given rectangle might, for example, have an X-coordinate that is in device units, a Y-coordinate that is in proportional units, a height that is in proportional units, and a width that is in device units, or any other combination of device and proportional units. :
- Rectangles that, when interpreted by using the current AbsoluteLayoutFlags set on the child, represent bounding boxes that are partially or wholly off-screen—for example, by having a width that is larger than the screen width—may give unexpected results.:

InvalidateMeasure(VisualElement) |
Layout updates can be forced by app code rather than relying on the built-in layout system behavior. However, that is not generally recommended. Calling InvalidateArrange, InvalidateMeasure or UpdateLayout is usually unnecessary and can cause poor performance if overused. In many situations where app code might be changing layout properties, the layout system will probably already be processing updates asynchronously. The layout system also has optimizations for dealing with cascades of layout changes through parent-child relationships, and forcing layout with app code can work against such optimizations. Nevertheless, it's possible that layout situations exist in more complicated scenarios where forcing layout is the best option for resolving a timing issue or other issue with layout. Just use it deliberately and sparingly. |
