thanks. you mean i can't use the Animation object anymore, and i should do the "blur" in my code . but the problem is i don't use the "blur" separately: i want to mix the blur , scale and alpha , so i need to code the "scale" and "alpha" myself ? the android use Skia to draw bitmap, so weather i can modify the framework to invoke a blurfilter in skia? it seems a big workload, any advice is appreciated !
