Здесь CoroutinesRetrofitActivity.kt

    var agentList = ObservableArrayList<Agent>()
    private lateinit var binding: CoroutinesRetrofitActivityBinding
    private lateinit var coroutinesRetrofitViewModel: CoroutinesRetrofitViewModel
    val isVisibleNoItems = ObservableBoolean()


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = CoroutinesRetrofitActivityBinding.inflate(layoutInflater)
        setContentView(binding.root)
        binding.setHandler(this);

 this.coroutinesRetrofitViewModel.getIsShowProgress()
            .observe(this, object : Observer<Boolean> {
                override fun onChanged(isShowProgress: Boolean?) {
                    findViewById<View>(R.id.containerProgressBarLayout).visibility =
                        if (isShowProgress!!) View.VISIBLE else View.GONE
                }
            });

    }

Но когда я пытаюсь построить, я получаю ошибку: 

> Task :app:checkDebugDuplicateClasses
> Task :app:javaPreCompileDebug

> Task :app:compileDebugJavaWithJavac
\testProjects\android\TestProjectAndroidKotlin\app\build\generated\source\kapt\debug\com\android\testproject\android\kotlin\databinding\CoroutinesRetrofitActivityBindingImpl.java:48: error: incompatible types: ProgressBarLayoutBinding cannot be converted to ViewDataBinding
        setContainedBinding(this.mboundView01);

Но если удалить изxml this: 

 <include
            layout="@layout/progress_bar_layout"
            android:visibility="gone" />

, тогда ошибка исчезнет.

Что не так с progress_bar_layout?

Если я включу индикатор выполнения в макет, например так: 

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

            type="com.android.testproject.android.kotlin.coroutine_retrofit.ui.activity.CoroutinesRetrofitActivity" />

    </data>

            app:layout_constraintTop_toTopOf="parent" />
    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

проблема исчезла.

Почему с include не работает? 

include
            layout="@layout/progress_bar_layout"
            android:visibility="gone" />

В progress_bar_layout используйте строку ниже (я также не уверен, что она работает для вас или нет, потому что я еще не пробовал, но если это сработает, я добавлю больше пояснений)

Возможно, эта ошибкадля совмещения привязки вида и привязки данных.Привязка вида не поддерживает переменные макета 

<androidx.constraintlayout.widget.ConstraintLayout
