第一种方法使用glide自带实现圆角方法
RoundedCorners roundedCorners = new RoundedCorners(5);圆角为5
RequestOptions options = RequestOptions.bitmapTransform(roundedCorners);
Glide.with(this)
.load(list.get(position).getImage())
.apply(options)
.into(holder.mUrl);
第二种:写一个自定义图片控件直接引用即可

2:attrs中加入
3:布局中直接引入并设置即可
<这里是你创建自定义view的包名.RadiuImageView
android:id="@+id/rmd_img"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
app:radius="5dp"//这里是四个角都圆角5dp,单独设置引入attrs中即可,比如左上右上角设置 app:left_top_radius="5dp"
app:right_top_radius="5dp"就可以
