A demonstration about how to inject BindingAdapters with Dagger Hilt.

HiltDataBinding.kt

BindingScoped.kt

@Scope
@Retention(AnnotationRetention.BINARY)
annotation class BindingScoped

-------------------------------------------------------

CustomBindingComponent.kt

@BindingScoped
@DefineComponent(parent = SingletonComponent::class)
interface CustomBindingComponent

-------------------------------------------------------

CustomBindingComponentBuilder.kt

@DefineComponent.Builder
interface CustomBindingComponentBuilder {
    fun build(): CustomBindingComponent
}

-------------------------------------------------------

CustomBindingEntryPoint.kt

@EntryPoint
@BindingScoped
@InstallIn(CustomBindingComponent::class)
interface CustomBindingEntryPoint: DataBindingComponent {

    @BindingScoped
    override fun getImageBindingAdapter(): ImageBindingAdapter
}

-------------------------------------------------------

MyApp.kt

@HiltAndroidApp
class MyApp : Application() {

    @Inject
    lateinit var bindingComponentProvider: Provider<CustomBindingComponentBuilder>

    override fun onCreate() {
        super.onCreate()

        val dataBindingComponent = bindingComponentProvider.get().build()
        val dataBindingEntryPoint = EntryPoints.get(
            dataBindingComponent, CustomBindingEntryPoint::class.java
        )

        DataBindingUtil.setDefaultComponent(dataBindingEntryPoint)
    }
}

@ModerPage it is working well for me. The only difference is that ApplicationComponent was replaced with SingletonComponent. Otherwise rest of the code remains the same. Please check and let me know if it works for you, too!

For those who are being stuck on this gist to fix issues running around Hilt and DataBinding implementation, I created a working sample repository for you! Please take a look at it if you want to see how it is working.

Thanks alot. its working now @nuhkoca

That's great to hear! @AhmMhd
