总结错误消息：您有一个NullPointerException，您试图访问一个空的对象函数变量，即未设置/初始化，此错误发生在文件MainActivity.java的第28行。您发布的文件是main_activity.java。这是打字错误还是您有两个mainactivity类？按钮在您的片段中，而不是在activity_主布局中。看@peant，那是个打字错误。对不起，我弄错了。谢谢@laalto。当我将活动_main更改为片段_main时。这个错误出现了。你能解释一下这个错误是什么意思吗找不到id为0x7f05003c com.example.sensormobileaty:id/片段占位符片段容器片段{40e30b10 id=0x7f05003c}'您的活动内容视图没有您尝试随片段事务附加的片段容器。
