android studio picasso circle image

1. Open your Android Studio project.

2. Ensure that you have the necessary dependencies in your app-level build.gradle file: kotlin implementation 'com.squareup.picasso:picasso:2.71828'

3. Sync your project to ensure that the new dependency is added.

4. In your XML layout file, add an ImageView where you want to display the circular image: xml <ImageView android:id="@+id/circularImageView" android:layout_width="100dp" android:layout_height="100dp" android:src="@drawable/placeholder_image" android:scaleType="centerCrop"/>

5. In your Kotlin activity or fragment file, reference the ImageView and load the image using Picasso: ```kotlin import com.squareup.picasso.Picasso

class YourActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.your_layout)

       val circularImageView: ImageView = findViewById(R.id.circularImageView)
       val imageUrl = "your_image_url_here"

       Picasso.get()
           .load(imageUrl)
           .transform(CircleTransform()) // Custom transformation for circular image
           .placeholder(R.drawable.placeholder_image) // Placeholder image while loading
           .error(R.drawable.error_image) // Image to display in case of an error
           .into(circularImageView)
   }

} ```

1. Create a custom transformation class for the circular image (CircleTransform.kt): ```kotlin import android.graphics.Bitmap import android.graphics.BitmapShader import android.graphics.Canvas import android.graphics.Paint import com.squareup.picasso.Transformation

class CircleTransform : Transformation { override fun transform(source: Bitmap): Bitmap { val size = Math.min(source.width, source.height) val x = (source.width - size) / 2 val y = (source.height - size) / 2

       val squaredBitmap = Bitmap.createBitmap(source, x, y, size, size)
       if (squaredBitmap != source) {
           source.recycle()
       }

       val bitmap = Bitmap.createBitmap(size, size, source.config)

       val canvas = Canvas(bitmap)
       val paint = Paint()
       val shader = BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP)
       paint.shader = shader
       paint.isAntiAlias = true

       val radius = size / 2f
       canvas.drawCircle(radius, radius, radius, paint)

       squaredBitmap.recycle()
       return bitmap
   }

   override fun key(): String {
       return "circle"
   }

} ```

1. Run your application to see the circular image loaded using Picasso.

Make sure to replace "your_image_url_here," "your_layout," "placeholder_image," and "error_image" with your actual image URL, layout, placeholder image resource, and error image resource, respectively.
