How to Create Circular ImageView in Android using CardView?

To create a circular ImageView in Android using CardView, you'll typically wrap the ImageView with a CardView and then make sure the CardView is circular. Here's how you can achieve this:

Add Dependencies:
If you haven't already added the CardView dependency to your project, open your app's build.gradle (Module: app) and add the following dependency:
```
implementation 'androidx.cardview:cardview:1.0.0'
```
Then sync your project.

XML Layout:

Use the CardView as a container for your ImageView in your XML layout:

<androidx.cardview.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_gravity="center"
    app:cardCornerRadius="50dp"
    app:cardElevation="5dp"
    app:cardPreventCornerOverlap="false">

    <ImageView
        android:id="@+id/myImageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop"
        android:src="@drawable/your_image_resource" />

</androidx.cardview.widget.CardView>

In this example, the width and height of the CardView are set to 100dp, and the corner radius (cardCornerRadius) is set to half of that (i.e., 50dp) to make the CardView completely circular.

Java/Kotlin Code (Optional):

You can then reference the ImageView in your Activity or Fragment's Java/Kotlin code:

ImageView myImageView = findViewById(R.id.myImageView);
// ... manipulate the ImageView as needed

val myImageView: ImageView = findViewById(R.id.myImageView)
// ... manipulate the ImageView as needed

Additional Tips:
- If you want a circular border (or stroke) around the ImageView, you can add a custom background to the CardView with a circular shape and stroke.
- Ensure your images have a consistent aspect ratio, or use android:scaleType="centerCrop" on the ImageView to make sure the images are centered and cropped within the circular view.

By using this method, you can create a circular ImageView using CardView without any third-party libraries.

Create Circular ImageView using CardView in Android:

Description: This topic covers the basic steps to create a Circular ImageView by combining a circular shape and a CardView in Android.

Example Code:

<androidx.cardview.widget.CardView
    android:layout_width="100dp"
    android:layout_height="100dp"
    app:cardCornerRadius="50dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/your_image"
        android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>

Customize Circular ImageView with CardView in Android Studio:

Description: Learn how to customize the appearance of the Circular ImageView and CardView, such as adjusting corner radius or adding shadows.

Example Code:

<androidx.cardview.widget.CardView
    android:layout_width="100dp"
    android:layout_height="100dp"
    app:cardCornerRadius="50dp"
    app:cardElevation="4dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/your_image"
        android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>

Design Circular ImageView with CardView border in Android:

Description: Add a border to the CardView containing the Circular ImageView for a more visually appealing design.

Example Code:

<androidx.cardview.widget.CardView
    android:layout_width="120dp"
    android:layout_height="120dp"
    app:cardCornerRadius="60dp"
    app:cardElevation="4dp"
    app:cardStrokeColor="@color/borderColor"
    app:cardStrokeWidth="2dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/your_image"
        android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>
