How to make an ImageView with rounded corners?

Question

In Android, an ImageView is a rectangle by default. How can I make it a rounded rectangle (clip off all 4 corners of my Bitmap to be rounded rectangles) in the ImageView?

With the help of glide library and RoundedBitmapDrawableFactory class it's easy to achieve. You may need to create circular placeholder image.

    Glide.with(context)
        .load(imgUrl)
        .asBitmap()
        .placeholder(R.drawable.placeholder)
        .error(R.drawable.placeholder)
        .into(new BitmapImageViewTarget(imgProfilePicture) {
            @Override
            protected void setResource(Bitmap resource) {
                RoundedBitmapDrawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(),
                        Bitmap.createScaledBitmap(resource, 50, 50, false));
                drawable.setCornerRadius(10); //drawable.setCircular(true);
                imgProfilePicture.setImageDrawable(drawable);
            }
        });
