NullPointerException in custom adapter getView

Question

I\'m coding a custom adapter for a ListView that has a custom list to it.

obviously, I have to write the getView function. so here is my code:

Answer 1

Change this:

vi = inflater.inflate(R.layout.result_list_item, null);

To this:

vi = inflater.inflate(R.layout.result_list_item, parent, false);

this is how your adapter should be:

public class NoPicAdapter extends ArrayAdapter {

    private ArrayList data;
    private Activity mActivity;
    private LayoutInflater inflater = null;

    public NoPicAdapter(Activity a, ArrayList d) {
        super(a, R.layout.no_pic_list_item, d);
        mActivity = a;
        data = d;
        inflater = (LayoutInflater) mActivity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }


    @Override
    public View getView(int position, @Nullable View convertView, ViewGroup parent) {
        View vi = convertView;
        if (vi == null)
            vi = inflater.inflate(R.layout.no_pic_list_item, parent, false);
        TextView title = (TextView) vi.findViewById(R.id.noPicTitle);
        TextView subtitle = (TextView) vi.findViewById(R.id.noPicSubtitle);

        title.setText(data.get(position).getmTitle());
        subtitle.setText(data.get(position).getmPubDate());

        return vi;
    }

}
