<polar>

LayoutWallpaper

Radial layout — places children at equal angular intervals on a circle of the given ring radius. Powers astrolabes, clock faces, and radial menus.

Example

<polar ringRadius="140dp" rotateChildren="outward">

Attributes

Name	Type	Default	Description
`gap`	`Dp`	—	Space between children
`padding`	`Dp`	—	Inner padding (single or top/right/bottom/left)
`background`	`Color`	—	Background color
`gradient`	`String`	—	Gradient brush: linear(...), radial(...), sweep(...)
`opacity`	`Float`	`1.0`	Container opacity (0.0–1.0)
`radius`	`Dp`	—	Corner radius
`align`	`String` `startcenterendstretchtopStarttopCentertopEndcenterStartcenterEndbottomStartbottomCenterbottomEnd`	`start`	Cross-axis alignment (column/row) or self-alignment within parent (box).
`justify`	`String` `startcenterendspaceBetweenspaceAroundspaceEvenly`	`start`	Main-axis distribution.
`fillMaxWidth`	`Boolean`	`false`	Fill available width
`fillMaxHeight`	`Boolean`	`false`	Fill available height
`flex`	`Float`	—	Flex weight for parent distribution
`rotate`	`Float`	—	Rotation in degrees (clockwise)
`scale`	`String`	—	Uniform scale factor, or 'sx,sy' for axis-specific
`offset`	`String`	—	Translation 'x,y' in dp or % (e.g. '8dp,-4dp' or '10%,0%')
`blur`	`Dp`	—	Blur radius (Dp) applied to the element and its children
`animate`	`String`	—	Animation preset shorthand, e.g. "pulse:2s", "breathe:4s", "spin:8s", "bob:3s:8dp", "sway:4s:6", "fade:3s:0.3:1", "shimmer:2s". Reads the shared animation clock so all animated elements stay phase-locked.
`ringRadius`	`Dp`	`100dp`	Distance from center to each child's center (distinct from common 'radius' = corner radius)
`startAngle`	`Float`	`-90`	Angle of the first child in degrees (-90 = 12 o'clock)
`sweep`	`Float`	`360`	Total angular span in degrees (360 closes the loop)
`direction`	`String` `cwccw`	`cw`	Winding direction.
`rotateChildren`	`String` `outwardinwardtangent`	—	Auto-rotate each child (`outward` is also accepted as `true`).
