Realize the ground glass effect in IOS in Android

In order to achieve the ground glass effect, we need a set of compute kernels (. Written in RS file) and a set of Java APIs used to control renderscript related (. RS file is automatically generated into Java class). Because the compilation of compute kernels requires a certain learning cost, from Jerry_ BEAN_ Since MR1, androied has built in some compute kernels for common operations, including Gaussian blur.

Next, let's explain how renderscript realizes Gaussian blur through practical operation, and finally achieve the effect (blurring the text background):

Implementation code:

The layout is as follows:
