android: create circular image with picasso

Question

The question had been asked and there had been a promise made for the very version of Picasso that I am using: How do I send a circular bitmap to an ImageView using Picasso?

Answer 1

This one is working with the current Picasso 3 snapshot:

class CircleTransformation : Transformation {

  override fun transform(source: RequestHandler.Result): RequestHandler.Result {
    if (source.bitmap == null) {
      return source
    }

    var bitmap: Bitmap

    // since we cant transform hardware bitmaps create a software copy first
    if (VERSION.SDK_INT >= VERSION_CODES.O && source.bitmap!!.config == Config.HARDWARE) {
      val softwareCopy = source.bitmap!!.copy(Config.ARGB_8888, true)
      if (softwareCopy == null) {
        return source
      } else {
        bitmap = softwareCopy
        source.bitmap!!.recycle()
      }
    } else {
      bitmap = source.bitmap!!
    }

    var size = bitmap.width
    // if bitmap is non-square first create square one
    if (size != bitmap.height) {
      var sizeX = size
      var sizeY = bitmap.height
      size = Math.min(sizeY, sizeX)
      sizeX = (sizeX - size) / 2
      sizeY = (sizeY - size) / 2

      val squareSource = Bitmap.createBitmap(bitmap, sizeX, sizeY, size, size)
      bitmap.recycle()
      bitmap = squareSource
    }

    val circleBitmap = Bitmap.createBitmap(size, size, Config.ARGB_8888)
    val canvas = Canvas(circleBitmap)
    val paint = Paint()
    val shader = BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP)

    paint.shader = shader
    paint.isAntiAlias = true
    val centerAndRadius = size / 2f
    canvas.drawCircle(centerAndRadius, centerAndRadius, centerAndRadius, paint)

    bitmap.recycle()
    return RequestHandler.Result(circleBitmap, source.loadedFrom, source.exifRotation)
  }

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

Answer 2

I have tried all solutions above but none of them gives me circle transform without cropping picture..those solution will work only for images with same width and height..this is my solution on above

first ------

Picasso.with(getActivity())
            .load(url)
            .error(R.drawable.image2)
            .placeholder(R.drawable.ic_drawer)
            .resize(200, 200)
            .transform(new ImageTrans_CircleTransform())
            .into(imageView1);

then do this --------

import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Shader.TileMode;

import com.squareup.picasso.Transformation;
public class ImageTrans_CircleTransform implements Transformation {
 @Override
    public Bitmap transform(Bitmap source) {
 if (source == null || source.isRecycled()) {
                return null;
            }

            final int width = source.getWidth() + borderwidth;
            final int height = source.getHeight() + borderwidth;

            Bitmap canvasBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
            BitmapShader shader = new BitmapShader(source, TileMode.CLAMP, TileMode.CLAMP);
            Paint paint = new Paint();
            paint.setAntiAlias(true);
            paint.setShader(shader);

            Canvas canvas = new Canvas(canvasBitmap);
            float radius = width > height ? ((float) height) / 2f : ((float) width) / 2f;
            canvas.drawCircle(width / 2, height / 2, radius, paint);

            //border code
            paint.setShader(null);
            paint.setStyle(Paint.Style.STROKE);
            paint.setColor(bordercolor);
            paint.setStrokeWidth(borderwidth);
            canvas.drawCircle(width / 2, height / 2, radius - borderwidth / 2, paint);
            //--------------------------------------

            if (canvasBitmap != source) {
                source.recycle();
            }

            return canvasBitmap;
}
 @Override
    public String key() {
        return "circle";
    }
}

Answer 3

This one worked for me

<com.androidhub4you.crop.RoundedImageView
        android:id="@+id/imageView_round"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_marginTop="15dp"
        android:src="@drawable/ic_launcher" />

Answer 4

Include the xml drawable of type Layer- list with the code below

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/shape_status">
        <shape android:shape="oval">
            <solid android:color="@android:color/black"/>
        </shape>
    </item>
<item android:drawable="@drawable/ic_status_content"/></layer-list>

then use the xml to your ImageView in the android.src

 <ImageView
            android:id="@+id/iconStatus"
            android:layout_width="55dp"
            android:layout_height="55dp"
            android:layout_gravity="right"
            android:src="@drawable/ic_circle_status"
            android:layout_alignParentTop="true"
            android:layout_alignParentEnd="true"/>
