You can accomplish this using different colored images, but when the rendering is the same for most of the part, using ColorStateList inside the Vector Drawable is a much better way. These changes might be as minor as a different colored stroke. Many a times we need to change the color of icons depending on the state of the button.

The same images rendered with different primary colors.(Image Courtesy: Android Dev Summit ‘18) This Vector Drawable renders an image of a battery in charging mode. Let’s take a look at a sample Vector Graphic as an SVG file and its corresponding XML Vector Drawable.
A path object inherits all the transformation of it’s ancestor groups. The group text is an internal node of the tree. The path will be joined in same order in which it appears in the file. The group contains data for transformation of the shape.
The path contains the actual geometric data to draw the object. It follows a tree hierarchy consisting of groups and paths. It is defined in a manner similar to the SVG format. This class defines a static drawable object. There are two classes that help you use Vector Drawables: VectorDrawable and AnimatedVectorDrawable. Imagine using animated Bitmaps in such a situation! If Bitmaps were used, developers had to use different images, one for each display resolution. Prior to this release if anyone wanted to represent images through Vector Graphics they had to do it manually though Java Code. The support for Vector Drawables was added in API Level 21(Lollipop). One can also animate them using multiple XML files.

This results in smaller APK files and less developer maintenance. Vector Drawables do not store pixels therefore they are of the same size independent of display density. the same file is resized for different screen densities.Ī Bitmap of higher resolution means more pixels. Vector Drawables look sharp on each display independent of display density, i.e. Why Vector Drawables?Īll Bitmaps have a specific resolution, which when displayed on a different density display may pixelate or might introduce unwanted artifacts. Animated Vector Drawables will be covered very briefly.

Normal Bitmaps are represented in the form of pixels… There are two basic ways an image can be represented in: Bitmaps and Vector Drawables. In this post we’ll be focuss Android Vector Drawables A Vector Drawable defines the image in the form of geometry, i.e as a set of points in the cartesian plane, connected through lines and curves, with their associated color information. Normal Bitmaps are represented in the form of pixels in a grid.
