round image using picasso in android -

provide url's regarding , xml code this,it having errors in image view phase

please check below 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, bitmapshader.tilemode.clamp, bitmapshader.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"; } 

after use picasso bind below.

picasso.with(activity).load(imagelink).transform(new circletransform()).into(imageview); 

hope work you.

let me know if have query.
