La liaison de vue ne fonctionne pas avec "Inclure": types incompatibles: ProgressBarLayoutBinding ne peut pas être converti en ViewDataBinding

Question

Android Studio 3.6. Canaries 12

build.gradle:

buildscript {
    ext.kotlin_version = '1.3.50'
    ext.RETROFIT_VERSION = '2.6.0'
    repositories {

    }
    dependencies {

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

dans app/build.gradle:

apply plugin: 'com.Android.application'

Ici CoroutinesRetrofitActivity.kt

class CoroutinesRetrofitActivity : AppCompatActivity(), AgentListItemAdapter.AdapterListener {
    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
                }
            });

    }

Mais quand j'essaye de construire, j'obtiens une erreur:

> 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);

Mais si je retire du xml ceci:

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

alors l'erreur a disparu.

Qu'est-ce qui ne va pas chez progress_bar_layout?

Si j'inclus directement la barre de progression dans une mise en page comme celle-ci:

<?xml version="1.0" encoding="utf-8"?>

    xmlns:app="http://schemas.Android.com/apk/res-auto"

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

le problème a disparu.

Pourquoi avec include ne fonctionne pas?

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

Answer 1

J'ai utilisé a_subsriber answer et cela fonctionne vraiment, mais assurez-vous de mettre les nampespaces xmlns dans la balise de mise en page mais pas dans la balise de vue

<layout xmlns:Android="http://schemas.Android.com/apk/res/Android">
