Android Matrix，getValues()返回什么? [英] Android Matrix, what does getValues() return?

问题描述

我在计算以下代码的返回值时遇到麻烦pMeasure = PathMeasure，m = Matrix，distCount是沿路径的距离

i'm having trouble working out the returned values of the below code pMeasure = PathMeasure, m = Matrix, distCount is the distance along the path

pMeasure.getMatrix(distCount, m, 0x01 | 0x02); 
m.getValues(float[] values)

float [2]& float [5]是位置x&分别是y，但我不知道其余的

float[2] & float[5] are position x & y respectively but i can't figure out the rest

任何帮助再次表示赞赏.

any help once again appreciated.
