Android Data Binding pass arguments to onClick with lambda expression

Question

I have an imageView with image loaded in it, and i want to open full screen activity with this image.

<layout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto">
<data>
    <variable
            name="obj"
            type="...ViewObjectImage">
    </variable>
    <variable
            name="handler"
            type="...Handlers">
    </variable>
</data>
<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >

    <android.support.v7.widget.CardView
            ...
        <ImageView
               ...
                app:progressbar="@{progressBar}"
                app:imageUrl="@{obj.url}"
                android:onClick="@{(v) -> handler.openFullScreen(v, obj.url)}"
                android:clickable="true"

my Handler class

 public void openFullScreen(View view, String url){
    Context context = view.getContext();
    Intent intent = new Intent(context, FullScreenSingleImageActivity.class);
    intent.putExtra("image_url", url);
    context.startActivity(intent);
}

But when I clicked on ImageView nothing happens. How can i pass second argument with lambda expression in right way?

Answer 2

I have this problem, because recyclerview contains different layouts (multiple view type). And all layouts used databinding. I setted handler only for layout in activity. Question was solved when I set handler in adapter to all layouts in recyclerview

@Override
public void onBindViewHolder(CommonViewHolder holder, int position) {
    Object object = getObjForPosition(position);
    holder.bind(object);
    holder.binding.setVariable(BR.handler, mHandlers);
}
