一个Android OS下实现的水波效果-Achieved under an Android OS Wave Effect! !

实现思路：波能扩散，波能衰减，交换波能数据缓冲区，计算偏移量，判断坐标是否在窗口范围内，计算出偏移象素和原始象素的内存地址偏移量-Realization of ideas: wave energy diffusion, wave energy attenuation, switching wave energy data buffer, offset calculation to determine whether the coordinates within the window, the c
