SimpleDraweeView 设置圆角不生效问题

采用的是xml配置 roundedCornerRadius 参数方法

adverPic.setImageURI("http://xx.xx.xx.xx/123.jpg");

设置control 也无效。
解决办法：

RoundingParams roundingParams = new RoundingParams();
                roundingParams.setCornersRadius(ScreenUtil.dpToPx(getResources(),15));
                GenericDraweeHierarchyBuilder builder = new GenericDraweeHierarchyBuilder(getResources());
                GenericDraweeHierarchy hierarchy = builder.build();
                hierarchy.setRoundingParams(roundingParams);
                adverPic.setImageURI(GlobalParams.gInitInfoEntity.getModel().getImage_url() + adverEntity.getImage_url());
                adverPic.setHierarchy(hierarchy);
