VectorDrawableCompat

public class VectorDrawableCompat extends Drawable


For API 24 and above, this class delegates to the framework's VectorDrawable. For older API version, this class lets you create a drawable based on an XML vector graphic.

You can always create a VectorDrawableCompat object and use it as a Drawable by the Java API. In order to refer to VectorDrawableCompat inside a XML file, you can use app:srcCompat attribute in AppCompat library's ImageButton or ImageView. Note: To optimize for the re-drawing performance, one bitmap cache is created for each VectorDrawableCompat. Therefore, referring to the same VectorDrawableCompat means sharing the same bitmap cache. If these references don't agree upon on the same size, the bitmap will be recreated and redrawn every time size is changed. In other words, if a VectorDrawable is used for different sizes, it is more efficient to create multiple VectorDrawables, one for each size. VectorDrawableCompat can be defined in an XML file with the <vector> element. The VectorDrawableCompat has the following elements:

<vector>

Used to define a vector drawable

android:name

Defines the name of this vector drawable.

android:width

Used to define the intrinsic width of the drawable. This support all the dimension units, normally specified with dp.

android:height

Used to define the intrinsic height the drawable. This support all the dimension units, normally specified with dp.

android:viewportWidth

Used to define the width of the viewport space. Viewport is basically the virtual canvas where the paths are drawn on.

android:viewportHeight

Used to define the height of the viewport space. Viewport is basically the virtual canvas where the paths are drawn on.

android:tint

The color to apply to the drawable as a tint. By default, no tint is applied.

android:tintMode

The Porter-Duff blending mode for the tint color. Default is src_in.

android:autoMirrored

Indicates if the drawable needs to be mirrored when its layout direction is RTL (right-to-left). Default is false.

android:alpha

The opacity of this drawable. Default is 1.

<group>

Defines a group of paths or subgroups, plus transformation information. The transformations are defined in the same coordinates as the viewport. And the transformations are applied in the order of scale, rotate then translate.

android:name

Defines the name of the group.

android:rotation

The degrees of rotation of the group. Default is 0.

android:pivotX

The X coordinate of the pivot for the scale and rotation of the group. This is defined in the viewport space. Default is 0.

android:pivotY

The Y coordinate of the pivot for the scale and rotation of the group. This is defined in the viewport space. Default is 0.

android:scaleX

The amount of scale on the X Coordinate. Default is 1.

android:scaleY

The amount of scale on the Y coordinate. Default is 1.

android:translateX

The amount of translation on the X coordinate. This is defined in the viewport space. Default is 0.

android:translateY

The amount of translation on the Y coordinate. This is defined in the viewport space. Default is 0.

<path>

Defines paths to be drawn.

android:name

Defines the name of the path.

android:pathData

Defines path data using exactly same format as "d" attribute in the SVG's path data. This is defined in the viewport space.

android:fillColor

Specifies the color used to fill the path. If this property is animated, any value set by the animation will override the original value. No path fill is drawn if this property is not specified.

android:strokeColor

Specifies the color used to draw the path outline. If this property is animated, any value set by the animation will override the original value. No path outline is drawn if this property is not specified.

android:strokeWidth

The width a path stroke. Default is 0.

android:strokeAlpha

The opacity of a path stroke. Default is 1.

android:fillAlpha

The opacity to fill the path with. Default is 1.

android:trimPathStart

The fraction of the path to trim from the start, in the range from 0 to 1. Default is 0.

android:trimPathEnd

The fraction of the path to trim from the end, in the range from 0 to 1. Default is 1.

android:trimPathOffset

Shift trim region (allows showed region to include the start and end), in the range from 0 to 1. Default is 0.

android:strokeLineCap

Sets the linecap for a stroked path: butt, round, square. Default is butt.

android:strokeLineJoin

Sets the lineJoin for a stroked path: miter,round,bevel. Default is miter.

android:strokeMiterLimit

Sets the Miter limit for a stroked path. Default is 4.

android:fillType

Sets the fillType for a path. The types can be either "evenOdd" or "nonZero". They behave the same as SVG's "fill-rule" properties. Default is nonZero. For more details, see FillRuleProperty

<clip-path>

Defines path to be the current clip. Note that the clip path only apply to the current group and its children.

android:name

Defines the name of the clip path.

android:pathData

Defines clip path using the same format as "d" attribute in the SVG's path data.
Gradient support We support 3 types of gradients: android.graphics.LinearGradient, android.graphics.RadialGradient, or android.graphics.SweepGradient. And we support all of 3 types of tile modes android.graphics.Shader.TileMode: CLAMP, REPEAT, MIRROR. Note that different attributes are relevant for different types of gradient.
LinearGradient RadialGradient SweepGradient
startColor startColor startColor
centerColor centerColor centerColor
endColor endColor endColor
type type type
tileMode tileMode tileMode
startX centerX centerX
startY centerY centerY
endX gradientRadius
endY
Also note that if any color item is defined, then startColor, centerColor and endColor will be ignored. Note that theme attributes in XML file are supported through inflate.
