Ошибка Android при попытке установить границу каждого элемента сетки

Question

Я пытаюсь GridView.Я сделал Адаптер, фрагмент и строку сетки XML.С GridView я пытаюсь сделать так, чтобы каждый элемент вида сетки был окружен рамкой, но я получаю ошибку, как показано ниже.

Адаптер:

public class GridViewAdapter extends BaseAdapter {
    //Imageloader to load images
    private ImageLoader imageLoader;

    //Context
    private Context context;

    public NetworkImageView networkImageView;
    public TextView textView;
    //Array List that would contain the urls and the titles for the images
    private ArrayList < String > names;
    private ArrayList < String > images;
    public SquareLayout l1;

    public GridViewAdapter(Context context, ArrayList < String > names, ArrayList < String > images) {
         //Getting all the values
         this.context = context;
         this.names = names;
         this.images = images;
    }

    @Override
    public int getCount() {
        return images.size();
    }

    @Override
    public Object getItem(int position) {
        return images.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public static class ViewHolder {
        public NetworkImageView networkImageView;
        public TextView textView;
    }@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // Creating a linear layout
        //  SquareLayout li=new SquareLayout(context);
        //  LinearLayout linearLayout = new LinearLayout(context);
        // l1.setOrientation(SquareLayout.Vert)
        // linearLayout.setOrientation(LinearLayout.VERTICAL);

        ViewHolder view;
        LayoutInflater inflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        // LayoutInflater inflator = context.getLayoutInflater();
        if (convertView == null) {
            view = new ViewHolder();
            convertView = inflator.inflate(R.layout.gridview_row, null);
            view.textView = (TextView) convertView.findViewById(R.id.textView1);
            view.networkImageView = (NetworkImageView) convertView.findViewById(R.id.imageView1);

            convertView.setTag(view);
        }
        else {
            view = (ViewHolder) convertView.getTag();
        }
        view.textView.setText(names.get(position));
        //textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
        //NetworkImageView
        NetworkImageView networkImageView = new NetworkImageView(context);

        //networkImageView.setImageResource(mThumbIds[position]);
        view.networkImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.networkImageView.setLayoutParams(new GridView.LayoutParams(50, 50));

        //Initializing ImageLoader
        imageLoader = CustomVolleyRequest.getInstance(context).getImageLoader();
        imageLoader.get(images.get(position), ImageLoader.getImageListener(networkImageView, R.mipmap.ic_launcher, android.R.drawable.ic_dialog_alert));

        //Setting the image url to load
        view.networkImageView.setImageUrl(images.get(position), imageLoader);
        view.networkImageView.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                // Intent intent= new Intent(context, CateFragment.class);
                //intent.putExtra("your_extra","your_class_value");
                //context.startActivity(intent);
                // v.getContext().startActivity(RegisterActivity.class);
                Toast.makeText(context, "You clicked on OK", Toast.LENGTH_SHORT).show();

                //Toast here
            }
        });

        //Scaling the imageview
        view.networkImageView.setScaleType(ImageView.ScaleType.CENTER_CROP);

        //networkImageView.setLayoutParams(new GridView.LayoutParams(200,200));
        //Adding views to the layout
        //linearLayout.addView(networkImageView);
        //linearLayout.addView(textView);
        //Creating a textview to show the title
        //TextView textView = new TextView(context);
        //Returnint the layout
        return convertView;
    }
}
