Research a bit before as there are answers available. Anyhow, follow <a href="https://gist.github.com/aprock/6213395" rel="noreferrer">This Link</a> and read it carefully to know how to use it.

try this:

<pre><code>import com.squareup.picasso.Transformation;

public class CircleTransform implements Transformation {
 @Override
 public Bitmap transform(Bitmap source) {
 int size = Math.min(source.getWidth(), source.getHeight());

 int x = (source.getWidth() - size) / 2;
 int y = (source.getHeight() - size) / 2;

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

 Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

 Canvas canvas = new Canvas(bitmap);
 Paint paint = new Paint();
 BitmapShader shader = new BitmapShader(squaredBitmap,
 Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
 paint.setShader(shader);
 paint.setAntiAlias(true);

 float r = size / 2f;
 canvas.drawCircle(r, r, r, paint);

 squaredBitmap.recycle();
 return bitmap;
 }

 @Override
 public String key() {
 return "circle";
 }
}
</code></pre>

then simply apply it like:

<pre><code>Picasso.with(activity).load(mayorShipImageLink).transform(new CircleTransform()).into(ImageView);
</code></pre>

Use this library to create a circular imageview.
<a href="https://github.com/Pkmmte/CircularImageView" rel="noreferrer">To make a circular ImageView, add this CircularImageView library to your project</a>
and add CircularImageView in your layout XML 

<pre><code>&lt;com.pkmmte.view.CircularImageView
 android:layout_width="250dp"
 android:layout_height="250dp"
 android:src="@drawable/image"
 app:border_color="#EEEEEE"

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

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 ------

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

then do this --------

<pre><code>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 &gt; 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";
 }
}
</code></pre>

blocks|key|4573369|text|我发现的另一个替代方案是这个guys库。它可以独立工作，也可以与毕加索一起工作。我选择了毕加索的路线，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4573370|https://github.com/vinc3m1/RoundedImageView|offset|length|4573371|Transformation+transformation+=+new+RoundedTransformationBuilder()

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

<a href="https://github.com/vinc3m1/RoundedImageView" rel="noreferrer">https://github.com/vinc3m1/RoundedImageView</a>

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

Picasso.with(context)
 .load(url)
 .fit()
 .transform(transformation)
 .into(imageView);
</code></pre>

Worked for me!

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

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

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 

<pre><code>Picasso.with(context).load(url).resize(w, h).into(imageview);
</code></pre>

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

android: create circular image with picasso

这个问题已经被问到了，并且已经为我正在使用的毕加索版本做出了承诺:如何使用毕加索将循环位图发送到ImageView？我刚接触毕加索，我唯一用过的就是Picasso.with(context).load(url).resize(w, h).into(imageview);我已经找到了，但我不确定如何以一种简单的方式将它与...
