获取网络图片并进行处理

已经能获得网络图片并展示了myPhoto.setImageBitmap(response.body());
现在是想要得到这张图片进行模糊处理，请问该怎么做？
模糊处理本地图片也是没问题的： private void myOnPreDrawListener() {
//毛玻璃效果
imgBlur.getViewTreeObserver().addOnPreDrawListener(
new ViewTreeObserver.OnPreDrawListener() {
@Override
public boolean onPreDraw() {
if (imgBlur.getMeasuredHeight() != 0) {
imgBlur.getViewTreeObserver().removeOnPreDrawListener(this);
imgBlur.setBackgroundResource(R.drawable.icon16);
imgBlur.buildDrawingCache();
Bitmap bmp = imgBlur.getDrawingCache();
// Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.icon16);
blur(bmp, imgBlur);
}
return true;
}
});
}
