Android 从片段到viewModel的数据绑定未更改

我将视图模型中的用户字段绑定到视图，但没有发现问题

当我调试时，用户正在返回正确的数据并将其保存在变量中，如fun setUser（）中所述，但更改没有绑定到视图。只有在init（）中更改其中一个，它才会在视图中更改！！！！我错过了什么

以下是viewModel：

    class ProfileViewModel  @ViewModelInject constructor(private val appRepository: AppRepository,
                                                              @Assisted private val savedStateHandle: SavedStateHandle
    ) :
            ViewModel() ,LifecycleObserver {
        var usertmp:User=User()
        var name: String = "hi"
        var mobile: String =  ""
        var mobile2: String = ""
        var password: String =  ""
        var address: String =  ""
        var balanceBegory:String =""
        var balanceEqlomat:String =""
        var studentLevel: String? = ""
        //var mTitleTV = savedStateHandle.getLiveData<String>("settingType").value
        var selectedData:String=""
    
    
        //clickable of button
        private val _isBtnAvailable = MutableLiveData<Boolean>()
        val isBtnAvailable: LiveData<Boolean>
            get() = _isBtnAvailable
        //to open main
        private val _isopenLogin = MutableLiveData<Boolean>()
        val isopenLogin: LiveData<Boolean>
            get() = _isopenLogin
        //progressbar

        val dataLoading: LiveData<Boolean>
            get() = _dataLoading
        private val _ishideKeyboard = MutableLiveData<Boolean>()
        val ishideKeyboard: LiveData<Boolean>
            get() = _ishideKeyboard
    
        private val msnackbarText = MutableLiveData<Event<Int>>()
        val snackbarMessage: LiveData<Event<Int>>
            get() = msnackbarText
        private val msnackbarText2 = MutableLiveData<String>()
        val snackbarMessage2: LiveData<String>
            get() = msnackbarText2
    
        init {
            _ishideKeyboard.value = false
            _isBtnAvailable.value = true
            getUser()
    //        address="test"
        }
    
        private fun getUser() {
            appRepository.getUserLastUpdate(object:IRemoteDataSource.LoginCallback{
                override fun onResponse(user: User) {
                    name="yes"
                    setuser(user)
                }
                override fun onDataNotAvailable(message: Int?) {
                    name="No"
                }
    
            })
    
        }

为了碎片

   @AndroidEntryPoint
   class ProfileFragment : Fragment(R.layout.fragment_profile),ProfileNavigator {
       private lateinit var binding:FragmentProfileBinding
   
       private val mLevelsList: ArrayList<Level> = ArrayList<Level>()

               container: ViewGroup?,
               savedInstanceState: Bundle?
       ): View? {
           Log.d(ContentValues.TAG, "showMessage: create profile")
           binding = FragmentProfileBinding.inflate(inflater, container, false)
           val view = binding.root

           binding.lifecycleOwner = this
           subscribeToNavigationChanges(profileViewModel)
           return view
       }
   ```
for profile fragment XML:

@雄蕊识别点
类ProfileFragment:Fragment（R.layout.Fragment\u profile），ProfileNavigator{
私有lateinit变量绑定：FragmentProfileBinding
private val mLevelsList:ArrayList=ArrayList（）
private val profileViewModel:profileViewModel by viewModels（）
覆盖创建视图(
充气机，
容器：视图组？，
savedInstanceState:捆绑？
)：查看{
Log.d（ContentValues.TAG，“showMessage:createprofile”）
绑定=碎片绑定。充气（充气机、容器、假）
val view=binding.root
binding.profileViewModel=profileViewModel
binding.lifecycleOwner=此
subscribeToNavigationChanges（profileViewModel）
返回视图
}
```
