compile 'jp.wasabeef:glide-transformations:2.0.1'
针对于3.7的版本
使用方法为：
//加载背景，
Glide.with(MusicPlayerActivity.this)
.load(service.getImageUri())
.dontAnimate()
.error(R.drawable.no_music_rotate_img)
// 设置高斯模糊,模糊程度(最大25) 缩放比例
.bitmapTransform(new BlurTransformation(this, 14, 3))
.into(allBg);针对4.+
Glide.with(context)
.load(url)
.apply(RequestOptions.bitmapTransform(new BlurTransformation(25,8)))
.into(view); BlurTransformation 类源码：
