How to Create Circular ImageView in Android using CardView?

Displaying images in Android is typically achieved using ImageView. However, if you wish to display a circular image, the process becomes more intricate. Many Android applications utilize CircularImageView to showcase profile pictures, status updates, stories, and more. Creating a circular image using CardView involves customizing the corner of the ImageView using cardCornerRadius. Below is a sample image illustrating what we aim to achieve in this guide. Our implementation will cover both Java and Kotlin Programming Languages for Android.

  • It includes essential code snippets that define the behavior of the main activity of an app.
• Key Components in the MainActivity File:
  • ImageView: This component handles the display of images in the app interface.
  • onCreate Method: This method is pivotal as it sets up the initial state of the activity.
• Code Snippets in Java and Kotlin:
  • In Java, the MainActivity file extends AppCompatActivity and contains code to handle image views and user interactions.
  • The Kotlin version of the MainActivity file demonstrates similar functionality using concise syntax.
