ActivityInfo.WindowLayout

public static final class ActivityInfo.WindowLayout
extends Object

java.lang.Object
   ↳ 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. 

Fields

public final int gravity

Gravity of activity.

public final int height

Height of activity in pixels.

public final float heightFraction

Height of activity as a fraction of available display height.

public final int minHeight

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

public final int minWidth

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

public final int width

Width of activity in pixels.

public final float widthFraction

Width of activity as a fraction of available display width.

Public constructors

XML attributes

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), 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.

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol defaultHeight.

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), 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.

This corresponds to the global attribute resource symbol defaultWidth.

android:gravity

Where to initially position the activity inside the available space. Uses constants defined in Gravity.

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

Constant Value Description
top 0x30 Push object to the top of its container, not changing its size.
bottom 0x50 Push object to the bottom of its container, not changing its size.
left 0x03 Push object to the left of its container, not changing its size.
right 0x05 Push object to the right of its container, not changing its size.
center_vertical 0x10 Place object in the vertical center of its container, not changing its size.
fill_vertical 0x70 Grow the vertical size of the object if needed so it completely fills its container.
center_horizontal 0x01 Place object in the horizontal center of its container, not changing its size.
fill_horizontal 0x07 Grow the horizontal size of the object if needed so it completely fills its container.
center 0x11 Place the object in the center of its container in both the vertical and horizontal axis, not changing its size.
fill 0x77 Grow the horizontal and vertical size of the object if needed so it completely fills its container.
clip_vertical 0x80 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.
clip_horizontal 0x08 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.
start 0x00800003 Push object to the beginning of its container, not changing its size.
end 0x00800005 Push object to the end of its container, not changing its size.

This corresponds to the global attribute resource symbol gravity.

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.

Must 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), mm (millimeters).

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol minHeight.

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.

This corresponds to the global attribute resource symbol minWidth.

height

Added in API level 24
int height

int minWidth

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

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.

width
