在我的ReserveFragment.kt代码下面巨大的这就是为什么共享为gist https://gist.github.com/kyodgorbek/b78a0fa14f949baf9209b8ff5914aa02
在我MapFragment.kt下面,当我单击上面的按钮时,出现异常
查看.OnClickListener {查看-〉
when (view.getId()) {
R.id.gotoBookingButton -> {
sharedPref.CurrentChargePoint = CurrentChargePoint
if (sharedPref.token.length > 0) {
Log.d("@@@@@@@", "${sharedPref.token}: ")
sharedPref.isAdhocBooking = false
findNavController().navigate(R.id.navigation_reserve) // in this line
} else {
findNavController().navigate(R.id.navigation_settings_login)
}
}
R.id.mapView -> {
StationInfo.isVisible = false
}
R.id.qrButton -> {
findNavController().navigate(R.id.activity_qr)
}
}
}
在我使用SharedPreferences的SharedPref.kt类下面
在我的服务器模块和共享首选项下。kt类https://gist.github.com/kyodgorbek/84f77dfd49a21066339053d5c6118883
我所尝试的我尝试了calling Fragment constructor caused an exception, kotlin?
所有stackoverflow回答模拟问题和无效缓存重新启动和调试它以及不成功任何建议非常感谢

问题出在这个变量上
您在此行中使用它
如果您提供
SharedPref
类,请检查您依赖模块
