步进传感器不计入文本视图（在片段中）

大佬教程收集整理的这篇文章主要介绍了步进传感器不计入文本视图（在片段中），大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决步进传感器不计入文本视图（在片段中）？

开发过程中遇到步进传感器不计入文本视图（在片段中）的问题如何解决？下面主要结合日常开发的经验，给出你关于步进传感器不计入文本视图（在片段中）的解决方法建议，希望对你解决步进传感器不计入文本视图（在片段中）有所启发或帮助；

我一直在使用片段在 androID studio（使用 kotlin）上做一个项目。我打算在另一个片段中实现一个步进传感器，但它没有用，也没有错误。我不知道错误在哪里。传感器看起来不错，但在文本视图中没有计算步数。我将传感器的代码放在片段类中。任何人都可以帮助我吗？应用程序没有崩溃，也没有告诉错误在哪里，只是没有计算步数

这是Fragment Class的代码
