Why does my onBindViewHolder () not run at all even though all my other recycler view methods run?

I have created a recycler view that is supposed to display data in a text view and an image view. But the onBindViewHolder () for my adapter does not run. All the other methods in my adapter run. I cannot find the reason why the onBindViewHolder () does not run, everything else seems to be working fine it's just my data is not displayed in the card views for my recycler view. Any help would be appreciated thanks.

Adapter code:

package com.myapps.myapplication;
import android.content.Context;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import androidx.recyclerview.widget.RecyclerView;
import androidx.cardview.widget.CardView;
public class captionedImagesAdapter extends RecyclerView.Adapter <captionedImagesAdapter.ViewHolder> {
private Context context;
private Cursor cursor;
public captionedImagesAdapter (Context context, Cursor cursor) {
this.context = context;
this.cursor = cursor;
}
public captionedImagesAdapter.ViewHolder onCreateViewHolder (ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(context);
CardView cv = (CardView) inflater.inflate(R.layout.card_view, parent, false);
return new ViewHolder (cv);
}
public void onBindViewHolder(ViewHolder holder, int position) {
if (cursor.moveToPosition(position)) {
return;
}
String info_text = cursor.getString (0);
byte [] info_image = cursor.getBlob(1);
Bitmap bitmap = MyDatabaseHelper.getImages(info_image);
holder.textView.setText(info_text);
holder.imageView.setImageBitmap(bitmap);
}
public int getItemCount() {
return cursor.getCount();
}
public static class ViewHolder extends RecyclerView.ViewHolder {
private ImageView imageView;
private TextView textView;
public ViewHolder(CardView view) {
super(view);
imageView = view.findViewById(R.id.info_image);
textView = view.findViewById(R.id.info_text);
}
}
}

}
public void accessDataBase () {
MyDatabaseHelper databaseHelper = new MyDatabaseHelper(this);
try {

cursor = db.query ("GROCERY_ITEMS", new String[] {"NAME", "IMAGE_RESOURCE_ID"}, null, null, null, null, null);
} catch (SQLiteException e) {
e.printStackTrace();
}
}
}

You're returning from onBindViewHolder() immediately:

> if (cursor.moveToPosition(position)) {
> return;
> }

moveToPosition() returns true on success.
