private lateinit var coroutinesRetrofitViewModel: CoroutinesRetrofitViewModel
val isVisibleNoItems = ObservableBoolean()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

setContentView(binding.root)
binding.setHandler(this);
this.coroutinesRetrofitViewModel.getIsShowProgress()

But when I try to build I get error:

estProjectsandroidTestProjectAndroidKotlinappuildgeneratedsourcekaptdebugcomandroidestprojectandroidkotlindatabindingCoroutinesRetrofitActivityBindingImpl.java:48: error: incompatible types: ProgressBarLayoutBinding cannot be converted to ViewDataBinding
setContainedBinding(this.mboundView01);
But if I remove from xml this:
<include
layout="@layout/progress_bar_layout"
android:visibility="gone" />
then error is gone.
What is wrong with progress_bar_layout
?
If I direct include progress bar in layout like this:
<?xml version="1.0" encoding="utf-8"?>

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
</layout>
the problem is gone.
Why with include
not work?
include
layout="@layout/progress_bar_layout"
android:visibility="gone" />
