You are using an import instead of a variable:
This:
<import alias="user" type="com.dubhe.room.entity.User" />
should be this:
<variable name="user" type="com.dubhe.room.entity.User" />

what I have tried
1.invalidate cache restart
2. I have checked xml carefully it did not solve problem
3. tried following After migration to androidX: Databinding problem (Android Studio 4) and ActivityMainBindingImpl cannot be found in this one as well it did not solve my problem
I want to know where I am making mistake

So what are the changes i should do to make it work? I have tried many SO threads already but none of them is working. Please help me out.

It appears you are binding to a property that doesn't exit. You have the userText in your xml which doesn't exist. Also you are binding to a model of the viewModel, so you need to make sure your SearchModel also implements BaseObservable.
Then make sure it is not private in your viewModel or that you write appropriate getters to retrieve it. The get and set Names MUST match the property name that is labeled with bindable.
Also just an architecture comment. I'm not sure why you would create a searchViewModel and a searchModel. Seems sort of redundant, but maybe you have reasons.
Example SEARCH MODEL below
class SearchModel : BaseObservable() {
#Bindable
private var searchText = ""
fun setSearchText(text: String){
searchModel.text = text
notifyPropertyChanged(BR.searchText)
}
fun getSearchText(): String{
return searchModel.text
}
}
Then your XML needs to be bound correctly to the models property
<EditText
android:id="#+id/inImageSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/search_hint"
android:maxLines="1"
android:text="#={viewModel.searchModel.searchText}" />
