Roman Samoylenko的答案是正确的，只是函数变了。 正确答案是

Glide.with(context)
                .load(yourImage)
                .apply(RequestOptions.circleCropTransform())
                .into(imageView);

                Glide.with(MainActivity.this)
                        .load(personPhoto)
                        .transition(withCrossFade(500))
                        .apply(RequestOptions.circleCropTransform())
                        .thumbnail(0.5f)
                        .into(imageView);

            

使用glide库，您可以使用以下代码:

Glide.with(context)
    .load(imageUrl)
    .asBitmap()
    .placeholder(R.drawable.user_pic)
    .centerCrop()
    .into(new BitmapImageViewTarget(img_profPic) {
        @Override
        protected void setResource(Bitmap resource) {
            RoundedBitmapDrawable circularBitmapDrawable = RoundedBitmapDrawableFactory.create(context.getResources(), resource);

            circularBitmapDrawable.setCircular(true);
            img_profPic.setImageDrawable(circularBitmapDrawable);
        }
    });

看看这篇文章，glide vs毕加索… 编辑:链接的文章并没有指出图书馆之间的重要区别。Glide会自动回收。详见TWiStErRob的评论。

Glide.with(this).load(URL).transform(new CircleTransform(context)).into(imageView);

public static class CircleTransform extends BitmapTransformation {
    public CircleTransform(Context context) {
        super(context);
    }

    @Override protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        return circleCrop(pool, toTransform);
    }

    private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
        if (source == null) return null;

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

        // TODO this could be acquired from the pool too
        Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);

        Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
        if (result == null) {
            result = Bitmap.createBitmap(size, size, Bitmap.Config.ARGB_8888);
        }

        Canvas canvas = new Canvas(result);
        Paint paint = new Paint();
        paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
        paint.setAntiAlias(true);
        float r = size / 2f;
        canvas.drawCircle(r, r, r, paint);
        return result;
    }

    @Override public String getId() {
        return getClass().getName();
    }
} 

最简单的方法(需要Glide 4.x.x)

Glide.with(context).load(uri).apply(RequestOptions.circleCropTransform()).into(imageView)

根据这个答案，两种语言中最简单的方法是:

科特林：

Glide.with(context).load(uri).apply(RequestOptions().circleCrop()).into(imageView)

Java:

Glide.with(context).load(uri).apply(new RequestOptions().circleCrop()).into(imageView)

这适用于Glide 4.X.X
