'android: create circular image with picasso

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? I am new to Picasso and only thing I have used is

Picasso.with(context).load(url).resize(w, h).into(imageview);

I have already found https://gist.github.com/julianshen/5829333 but I am not sure how to combine it with the line above in a non-awkward way.

Solution 1:^[1]

here is something that's provided by the support-v4 library! Look into RoundedBitmapDrawable. No need to roll your own:

Picasso.with(context).load(url)
                        .resize(w, h)
                        .into(myImageView, new Callback() {
                            @Override
                            public void onSuccess() {
                                Bitmap imageBitmap = ((BitmapDrawable) myImageView.getDrawable()).getBitmap();
                                RoundedBitmapDrawable imageDrawable = RoundedBitmapDrawableFactory.create(getResources(), imageBitmap);
                                imageDrawable.setCircular(true);
                                imageDrawable.setCornerRadius(Math.max(imageBitmap.getWidth(), imageBitmap.getHeight()) / 2.0f);
                                myImageView.setImageDrawable(imageDrawable);
                            }
                            @Override
                            public void onError() {
                                myImageView.setImageResource(R.drawable.default_image);
                            }
                        });

Note: Picasso also has a .transform(customTransformation) call that you could theoretically use, however, I had issues with that. This above works. Good luck!

Solution 2:^[2]

There is a transformation library for Picasso.

Just add gradle dependency

implementation 'jp.wasabeef:picasso-transformations:2.4.0'

End use it

Picasso.with(context)
       .load(url)
       .resize(w, h)
       .transform(new CropCircleTransformation())
       .into(imageview);

Wiki: Picasso Transformations

Solution 3:^[3]

Another alternative I found was this guys library. It works standalone, or in conjunction with Picasso. I chose the Picasso route, like below:

https://github.com/vinc3m1/RoundedImageView

Transformation transformation = new RoundedTransformationBuilder()
          .borderColor(Color.BLACK)
          .borderWidthDp(3)
          .cornerRadiusDp(30)
          .oval(false)
          .build();

Picasso.with(context)
    .load(url)
    .fit()
    .transform(transformation)
    .into(imageView);

Worked for me!

Solution 4:^[4]

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";
    }
}

Use this library to create a circular imageview. To make a circular ImageView, add this CircularImageView library to your project and add CircularImageView in your layout XML

<com.pkmmte.view.CircularImageView
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:src="@drawable/image"
        app:border_color="#EEEEEE"
        app:border_width="4dp"
        app:shadow="true" />`

Then use picasso to load required image into this imageView. Picasso does all the caching you dont need to worry about it

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" />

Solution 7:^[7]

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"/>

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()"
  }
}

Here is what worked for me with Picasso v2.71828

class CircleTransform : Transformation {
override fun transform(source: Bitmap?): Bitmap? {
    if (source == null) {
        return source
    }

    var bitmap: Bitmap

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

    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, Bitmap.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 circleBitmap
}


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