图片圆角并且是CENTERCROP属性的情况下

当图片设置

android:scaleType="centerCrop"

属性，又要实现圆角图片的时候，出现的一些问题，当设置centerCrop的时候，圆角就没有了，

这个时候需要用到另一个方法，设置两个Transformer

Glide.with(mContext)
        .load(vo.getImage())
        .dontAnimate()
        .placeholder(R.drawable.noinfo)
        .error(R.drawable.noinfo)
        .transform(new CenterCrop(mContext),new GlideRoundTransform(mContext, 10))
        .into(imgs1);

 

GlideRoundTransform
