Glide.with(App.getContext()).load(bean.getHeadImage())
                .dontAnimate()
                .placeholder(R.drawable.default_image)
                .error(R.drawable.default_image)
                .transform(,new GlideRoundTransform(App.getContext(),10))
                .into(headIv);

GlideRoundTransform 封裝

public class GlideRoundTransform extends BitmapTransformation {

    }
 
    @Override
    protected Bitmap transform(BitmapPool pool, Bitmap toTransform, int outWidth, int outHeight) {
        return roundCrop(pool, toTransform);
    }
 
    private static Bitmap roundCrop(BitmapPool pool, Bitmap source) {
