WindowLayout

class WindowLayout
kotlin.Any
   ↳ android.content.pm.ActivityInfo.WindowLayout

Contains information about position and size of the activity on the display. Used in freeform mode to set desired position when activity is first launched. It describes how big the activity wants to be in both width and height, the minimal allowed size, and the gravity to be applied.

Summary

XML attributes
android:defaultHeight Default height of the activity.
android:defaultWidth Default width of the activity.
android:gravity Where to initially position the activity inside the available space.
android:minHeight Minimal height of the activity.
android:minWidth Minimal width of the activity.
Public constructors
WindowLayout(width: Int, widthFraction: Float, height: Int, heightFraction: Float, gravity: Int, minWidth: Int, minHeight: Int)
Properties
Int

Gravity of activity.
Int

Height of activity in pixels.
Float

Height of activity as a fraction of available display height.
Int

Minimal height of activity in pixels to be able to display its content.
Int

Minimal width of activity in pixels to be able to display its content.
Int

Width of activity in pixels.
Float

Width of activity as a fraction of available display width.

XML attributes

android:defaultHeight

android:defaultHeight
 Default height of the activity. Can be either a fixed value or fraction, in which case the height will be constructed as a fraction of the total available height.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

android:defaultWidth

android:defaultWidth
 Default width of the activity. Can be either a fixed value or fraction, in which case the width will be constructed as a fraction of the total available width.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

android:gravity

android:gravity
 Where to initially position the activity inside the available space. Uses constants defined in android.view.Gravity.

Must be one or more (separated by '|') of the following constant values.

Constant Value Description
bottom 50 Push object to the bottom of its container, not changing its size.
center 11 Place the object in the center of its container in both the vertical and horizontal axis, not changing its size.
center_horizontal 1 Place object in the horizontal center of its container, not changing its size.
center_vertical 10 Place object in the vertical center of its container, not changing its size.
clip_horizontal 8 Additional option that can be set to have the left and/or right edges of the child clipped to its container's bounds. The clip will be based on the horizontal gravity: a left gravity will clip the right edge, a right gravity will clip the left edge, and neither will clip both edges.
clip_vertical 80 Additional option that can be set to have the top and/or bottom edges of the child clipped to its container's bounds. The clip will be based on the vertical gravity: a top gravity will clip the bottom edge, a bottom gravity will clip the top edge, and neither will clip both edges.
end 800005 Push object to the end of its container, not changing its size.
fill 77 Grow the horizontal and vertical size of the object if needed so it completely fills its container.
fill_horizontal 7 Grow the horizontal size of the object if needed so it completely fills its container.
fill_vertical 70 Grow the vertical size of the object if needed so it completely fills its container.
left 3 Push object to the left of its container, not changing its size.
right 5 Push object to the right of its container, not changing its size.
start 800003 Push object to the beginning of its container, not changing its size.
top 30 Push object to the top of its container, not changing its size.

android:minHeight

android:minHeight
 Minimal height of the activity.

NOTE: A task's root activity value is applied to all additional activities launched in the task. That is if the root activity of a task set minimal height, then the system will set the same minimal height on all other activities in the task. It will also ignore any other minimal height attributes of non-root activities.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

android:minWidth

android:minWidth
 Minimal width of the activity.

NOTE: A task's root activity value is applied to all additional activities launched in the task. That is if the root activity of a task set minimal width, then the system will set the same minimal width on all other activities in the task. It will also ignore any other minimal width attributes of non-root activities.
