android-fragments 片段膨胀不是预期的xml文件

我遇到了一个问题，即EditSleepPressureFactorFragment膨胀了其他xml文件fragment_sleep_record.xml。但我的目的是膨胀fragment_edit_sleep_pressure.xml。ID为“year_spinner”的Spinner位于fragment_edit_sleep_pressure.xml中，但binding!!.yearSpinner代码出现了未解决的引用。binding!!.startSleepYear代码未导致错误。“start_sleep_year”ID位于fragment_sleep_record.xml中。如何解决此问题？

使用文件名fragment_edit_sleep_pressure_factor.xml和binding：

binding = FragmentEditSleepPressureFactorBinding.inflate(inflater)
