如何将加速度传感器数据转换为步数计数器？

Question

我想用颤动构建一个步数计数器小部件，但不知道如何借助传感器颤振包将X，Y和Z轴的加速度传感器数据转换为步数计数器。

I think trying to do this accurately from accelerometer data may be tricky, so you may be better trying to do it natively in a plugin. For example, Android has a Step Counter sensor type:

If you insist on doing it from the accelerometer data, I think you probably want to count the direction changes (count every other one), but I expect making it accurate (eg. trying to ignore things that aren't steps) will be non-trivial.
