Estoy tratando de crear una vista de cuadrícula que cargue la URL en ella. Puedo hacerlo funcionar en MainActivity pero cuando pego mi código en Gridview. La imagen no se muestra.

Aquí está mi código en Fragment

public static String[] eatFoodyImages = {
        "http://image.tmdb.org/t/p/w185//nBNZadXqJSdt05SHLqgT0HuC5Gm.jpg",
        "http://i.imgur.com/C9pBVt7.jpg",
};

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_main, container, false);
    // Inflate the layout for this fragment

    GridView gridview = (GridView) rootView.findViewById(R.id.gridview);
    gridview.setAdapter(new ImageListAdapter(getActivity(), eatFoodyImages));

    return inflater.inflate(R.layout.fragment_main, container, false);
}

Activity_main.xml

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

android:layout_height="200dp">

ImageListAdapter:

public class ImageListAdapter extends ArrayAdapter {
private Context context;
private LayoutInflater inflater;

private String[] imageUrls;

public ImageListAdapter(Context context, String[] imageUrls) {
    super(context, R.layout.image_view, imageUrls);

    this.context = context;
    this.imageUrls = imageUrls;

    inflater = LayoutInflater.from(context);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if (null == convertView) {
        convertView = inflater.inflate(R.layout.image_view, parent, false);
    }

    Picasso
            .with(context)
            .load(imageUrls[position])
            .fit() // will explain later
            .into((ImageView) convertView);

    return convertView;
}
}
