Crafting Personalized Avatars with the CompositionAvatar Library

Robert Harris -

In the realm of Android development, crafting a visually appealing interface is paramount. The CompositionAvatar library, developed by Huangweijun, emerges as a powerful tool for generating diverse avatars effortlessly within Android applications. With its roots in Kotlin, this library, still under active development, is available under the Apache 2.0 license.

The CompositionAvatar library extends a plethora of features that enable the creation of engaging avatars:

  • It supports a range of avatar styles including circular, square, and elliptical shapes.
  • The library caters to the customization of avatar styles, thereby offering a broader canvas for creativity.
  • It allows for the manipulation of avatar backgrounds and text, enriching the avatar generation experience.

Embarking on the journey with CompositionAvatar begins with importing the library using the following snippet:

dependencies {
  implementation 'com.github.huangweijun:compositionavatar:1.0.0'
}

Generating an avatar is a simple affair with CompositionAvatar:

// Generate an avatar
val avatar = CompositionAvatar(
  style = Style.CIRCLE,
  background = Color.RED,
  text = "Hello, world!",
  textColor = Color.WHITE,
)

Dive deeper by customizing the avatar style to your liking:

// Customize the avatar style
val avatar = CompositionAvatar(
  style = Style.ELLIPSE,
  background = Color.YELLOW,
  text = "Hello, world!",
  textColor = Color.BLACK,
  textSize = 24f,
  backgroundColor = Color.TRANSPARENT,
  borderColor = Color.BLACK,
  borderWidth = 2f,
  shadowColor = Color.GRAY,
  shadowRadius = 10f,
  shadowOffsetX = 10f,
  shadowOffsetY = 10f,
)

The CompositionAvatar library is a boon for both novices and seasoned developers in the Android ecosystem, although the less active community and sparse documentation leave room for enhancement.
