layout_height doesn't work in layout file when using DataBinding

Question

I'm getting a list of users from a back-end server and I display in a RecyclerView. I have a layout file for each row. This is what I have tried:

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

    <data class="UserDataBinding">
        <variable
            name="user"
            type="com.example.myapp.User" />
    </data>

    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="150dp"
        android:layout_margin="2dp">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <ImageView
                android:id="@+id/poster_path_image_view"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:contentDescription="@null"
                android:scaleType="centerCrop" />

            //Other views
    </androidx.cardview.widget.CardView>
</layout>

My goal is to display only the profile pictures. The problem is that even if I set the layout_height to 150dp, the picture is displayed very small. Even if I increase the height nothing happens. How to set the CardView/ImageView to have a fixed height?

Edit:

I found the solution. I forgot to inflate the view. This line solved the problem:

ListItemBinding binding = DataBindingUtil.inflate(layoutInflater, R.layout.list_item, viewGroup, false);

As @DavidWasser suggested, I added the solution as an answer to my own question. The problem was that I forgot to inflate the view. This line solved my problem:

ListItemBinding binding = DataBindingUtil.inflate(layoutInflater, R.layout.list_item, viewGroup, false);
