How to create a Circular image view in Android without using any library?

Creating a circular ImageView without using any library requires you to create a custom Drawable or use a CardView with rounded corners. Here's how you can achieve it:

Method 1: Using a Custom Drawable

  • Create a custom BitmapDrawable:

Create a new Kotlin file CircularBitmapDrawable.kt and add the following code:

import android.graphics.*
import android.graphics.drawable.BitmapDrawable
import android.graphics.drawable.Drawable

class CircularBitmapDrawable(private val bitmap: Bitmap) : Drawable() {

    private val paint = Paint().apply {
        isAntiAlias = true
        shader = BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP)
    }

    override fun draw(canvas: Canvas) {
        val cx = bounds.width() / 2f
        val cy = bounds.height() / 2f
        val radius = Math.min(cx, cy)
        canvas.drawCircle(cx, cy, radius, paint)
    }

    override fun setAlpha(alpha: Int) {
        paint.alpha = alpha
    }

    override fun setColorFilter(cf: ColorFilter?) {
        paint.colorFilter = cf
    }

    override fun getOpacity(): Int {
        return PixelFormat.TRANSLUCENT
    }

    override fun getIntrinsicWidth(): Int {
        return bitmap.width
    }

    override fun getIntrinsicHeight(): Int {
        return bitmap.height
    }
}
  • Use the custom drawable:
val bitmap = BitmapFactory.decodeResource(resources, R.drawable.your_image)
val circularBitmapDrawable = CircularBitmapDrawable(bitmap)

imageView.setImageDrawable(circularBitmapDrawable)

Method 2: Using CardView with Rounded Corners

  • Add CardView Dependency:

If you haven't added it yet, include the CardView dependency in your build.gradle (Module: app):

implementation 'androidx.cardview:cardview:1.0.0'
  • Use CardView in your layout:

In your XML layout, wrap the ImageView with CardView:

<androidx.cardview.widget.CardView
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:layout_gravity="center"
    app:cardCornerRadius="50dp"
    app:cardElevation="0dp"
    app:cardBackgroundColor="@android:color/transparent">

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

</androidx.cardview.widget.CardView>

The key here is setting the app:cardCornerRadius to half of the width/height of the CardView to make it circular.

These methods allow you to achieve a circular ImageView effect without relying on third-party libraries, giving you more control over the rendering process.

  1. Create Circular ImageView in Android programmatically:

    • Description: To create a Circular ImageView programmatically, you need to set the background to an oval shape and clip the ImageView to its outline.

    • Code:

      ImageView circularImageView = new ImageView(context);
circularImageView.setLayoutParams(new ViewGroup.LayoutParams(150, 150));
circularImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
circularImageView.setImageResource(R.drawable.profile_image);

// Set circular shape programmatically
circularImageView.setBackground(new ShapeDrawable(new OvalShape()));
circularImageView.setClipToOutline(true);

// Add the ImageView to the parent layout
parentLayout.addView(circularImageView);

  2. How to make a circular image view in Android:

    • Description: Making a Circular ImageView involves setting the background shape to an oval and clipping it to the outline.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    android:src="@drawable/profile_image"
    android:background="@drawable/circular_shape" />
      • res/drawable/circular_shape.xml:
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#000000" />
</shape>

  3. Circular image view in Android without external library:

    • Description: Creating a Circular ImageView without using an external library can be achieved using standard Android features.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    android:src="@drawable/profile_image"
    android:background="@drawable/circular_shape" />
      • res/drawable/circular_shape.xml:
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#000000" />
</shape>

  4. Android ImageView circular shape without library:

    • Description: Achieving a circular shape for an ImageView without using an external library involves defining a circular shape in XML.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    android:src="@drawable/profile_image"
    android:background="@drawable/circular_shape" />
      • res/drawable/circular_shape.xml:
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#000000" />
</shape>

  5. Draw circular shape around ImageView in Android:

    • Description: Drawing a circular shape around an ImageView involves using an oval shape as the background.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    android:src="@drawable/profile_image"
    android:background="@drawable/circular_shape" />
      • res/drawable/circular_shape.xml:
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#000000" />
</shape>

  6. Programmatic approach to circular ImageView in Android:

    • Description: Programmatically creating a Circular ImageView involves setting the background shape to an oval and clipping it to the outline.

    • Code:

      ImageView circularImageView = new ImageView(context);
circularImageView.setLayoutParams(new ViewGroup.LayoutParams(150, 150));
circularImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
circularImageView.setImageResource(R.drawable.profile_image);

// Set circular shape programmatically
circularImageView.setBackground(new ShapeDrawable(new OvalShape()));
circularImageView.setClipToOutline(true);

// Add the ImageView to the parent layout
parentLayout.addView(circularImageView);

  7. Implement circular image view without third-party library in Android:

    • Description: Implementing a Circular ImageView without using a third-party library involves setting the background to an oval shape and clipping it to the outline.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:scaleType="centerCrop"
    android:src="@drawable/profile_image"
    android:background="@drawable/circular_shape" />
      • res/drawable/circular_shape.xml:
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#000000" />
</shape>

  8. Customize circular shape for ImageView in Android:

    • Description: Customize the circular shape for an ImageView by adjusting the attributes in the oval shape XML.

    • Code:

      <ImageView
    android:id="@+id/circularImageView"
    android:layout_width="150dp"
    android:layout_height="150dp"
