DataBinding: How to create RecyclerView Adapter with same model and different layout?

Question

I use same adapter for two different item layouts. One is for grid, one is for linear display. I'm passing layout id with itemLayout to adapter. However, I wasn't able to add data binding properly. Could you help me out, please?

Here is my adapter effort so far:

public class OyuncuAdapter extends RecyclerView.Adapter<OyuncuAdapter.ViewHolder> {

    ArrayList<Oyuncu> oyuncuListesi;
    Context context;
    int itemLayout;

    public OyuncuAdapter(ArrayList<Oyuncu> oyuncuListesi, Context context, int itemLayout) {
        this.oyuncuListesi = oyuncuListesi;
        this.context=context;
        this.itemLayout = itemLayout;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {         
        View v = LayoutInflater.from(context).inflate(itemLayout, parent, false);
        return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        Oyuncu oyuncu = oyuncuListesi.get(position);
        holder.binding.setVariable(BR.oyuncu, oyuncu);
        holder.binding.executePendingBindings();

    }

    @Override
    public int getItemCount() {
        return oyuncuListesi.size();
    }

    public static class ViewHolder extends RecyclerView.ViewHolder{

        private ViewDataBinding binding;

        public ViewHolder(View itemView) {
            super(itemView);
            binding = DataBindingUtil.bind(itemView);

        }
    }
}

Here is the item layout:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <data>

        <variable
            name="oyuncu"
            type="com.figengungor.suits.model.Oyuncu" />

    </data>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:orientation="vertical"
        android:padding="@dimen/itemPadding"
        tools:background="@color/darkgrey">

        <ImageView
            android:id="@+id/foto"
            android:layout_width="150dp"
            android:layout_height="150dp"
            android:gravity="center"
            android:scaleType="centerCrop"
            app:imageResource="@{oyuncu.foto}"
            tools:src="@drawable/gabrielmacht" />

        <TextView
            android:id="@+id/isim"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:textColor="@android:color/white"
            android:text="@{oyuncu.isim}"
            tools:text="Gabriel Macht" />

    </LinearLayout>

</layout>

The error I'm getting is not really helpful:

Caused by: java.lang.RuntimeException: view tag isn't correct on view:null

My bad. This part works perfectly. My problem is extending BaseActivity which also uses DataBinding. The crash is related to that. After removing extending BaseActivity from my activity, it worked. However, I opened another question realted to that. If you could look at that, I'll be grateful. DataBinding: How to use BaseActivity
