Binding Adapter not working properly

Question

I have a hard time making @BindingAdapter to work in my project.

@BindingAdapter("imageUrl")
public static void setImageUrl(ImageView imageView, String url) {
    Log.d("TEST","URL: " + url);
}

Above code shows how it is implemented in my ViewModel. Nothing special.

    <ImageView
        android:id="@+id/image_holder"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scaleType="centerCrop"
        android:layout_below="@id/profile_container"
        app:imageUrl="@{item.imageUrl}"
        tools:src="@drawable/placeholder_image"/>

This does not work. namespace app is unbound. So what am i missing. I tried following https://medium.com/google-developers/android-data-binding-custom-setters-55a25a7aea47#.6ygaiwooh and see how they set bindingAdapter. But there is something i have missed

Answer 1

I encountered the same problem, I missed to bind layout using:

DataBindingUtil.setContentView(activity, layoutResId);
