推荐答案

你可能想看一下 http://android-developers.blogspot.com/2013/08/renderscript-intrinsics.html [ ^ ]，您还可以使用c ++实现快速模糊，请参阅https://www.ibm.com/developerworks/opensource/tutorials/os-androidndk/ [ ^ ]但您可以使用renderscript优化模糊 http://docs.xamarin.com/recipes/android/other_ux/drawing/blur_an_image_with_renderscript/ [ ^ ]

You might want to look at http://android-developers.blogspot.com/2013/08/renderscript-intrinsics.html[^], you can also implement a fast blur using c++ see https://www.ibm.com/developerworks/opensource/tutorials/os-androidndk/[^] but you can use optimized blurring with renderscript http://docs.xamarin.com/recipes/android/other_ux/drawing/blur_an_image_with_renderscript/[^]
