#RxBlur

Overview

在Android设备上,实现一个毛玻璃(高斯模糊)效果总是让人很棘手,不仅要考虑视觉效果,还要在性能和代码实现的复杂度上做出权衡。 这里归纳和总结了几种实现方案(PS: GitHub + StackOverflow + DIY),并且用RxJava进行封装,方便以流的形式处理图片的加载和操作。

Project Structure

  • MainActivity: RxJava + RxBinding + RxViewStub + BestBlur

  • PicassoBlurActivity: RxJava + Picasso + Transformation + RenderScript

  • GlideBlurActivity: RxJava + Glide + Transformation + RenderScript

  • RemoteBlurActivity: RxJava + Retrofit + BestBlur

  • FastBlurActivity: RxJava + Picasso + FastBlur

  • PaintBlurActivity: RxJava + Picasso + PaintBlur

  • RxAnimatorBlurActivity: RxJava + Picasso + Animator(TypeEvaluator)

Summary

把它运行起来,然后看一下高斯效果,这里我还计算了每种模糊算法的所耗时长,方便您的选择,虽然BestBlur在代码的复杂度上很难令人接受,但是在性能表现和模糊效果上还是令人满意的,所以,综合考虑,它是个不错的选择,而且,还可以设置模糊灰度。

如果您对RxJava更感兴趣,可以按照我的实现思路,扩展自己需要的“RxBinding”。

如果,您发现了它的不当之处或者更好地实现思路与方案,请联系我,谢谢。
