How to get a reference to inner view of itembinding

[edlman]

I'm trying to get a reference to inner view (VideoView) of a page in PagerView. There is a fragment XML definition which contains

        <androidx.viewpager.widget.ViewPager
            android:id="@+id/pager"
            android:layout_width="0dp"
            android:layout_height="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintBottom_toTopOf="@id/tabs"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:items="@{vm.items}"
            app:itemBinding="@{vm.itemBinding}"/>

The ViewModel class contains

    val items = MutableLiveData<List<TutorialScreenModel>>()
    val itemBinding = ItemBinding.of<TutorialScreenModel>(BR.model, R.layout.page_tutorial).bindExtra(BR.listener, this)

and page_tutorial.xml layout contains

        ...
        <VideoView
            android:id="@+id/videoView"
            ....

And I want to get reference to this VideoView. But I didn't find a way how to. It's not possible via itemBinding.

Not directly. You can either subclass the adapter and get a reference to it in onBindBinding or pass the view to the model you are binding in xml.

Hello Evan,

thanks for reply. I did it using my own adapter. But it's a pitty it's not possible to access inner views on ItemBinding.

Not directly. You can either subclass the adapter and get a reference to it in |onBindBinding| or pass the view to the model you are binding in xml.
