Android error using Picasso

Question

I have the following code to display images through URL

public class AdapterListPesquisaResp extends BaseAdapter {

private ImageLoader il;

    private LayoutInflater mInflater;
    private ArrayList<ItemListaPesquisaResp> itens;
    Context context;

    public AdapterListPesquisaResp(Context context, ArrayList<ItemListaPesquisaResp> itens) {
        this.itens = itens;
        mInflater = LayoutInflater.from(context);
    }

    public int getCount() {
        return itens.size();
    }


    public ItemListaPesquisaResp getItem(int position) {
        return itens.get(position);
    }


    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View view, ViewGroup parent) {

        ItemSuporte itemHolder;
        if (view == null) {
            view = mInflater.inflate(R.layout.texto_resposta_pesquisa, null);

            itemHolder = new ItemSuporte();
            itemHolder.txtTitle = ((TextView) view.findViewById(R.id.txtnome_resp_pesquisa));
            itemHolder.txtTrabalho = ((TextView) view.findViewById(R.id.txttrabalho_resp_pesquisa));
            itemHolder.txtkm = ((TextView) view.findViewById(R.id.txtkm_resp_pesquisa));
            itemHolder.imgIcon = ((ImageView) view.findViewById(R.id.imagemviewfoto_resp_pesquisa));
            itemHolder.imgnota = ((ImageView) view.findViewById(R.id.imageView_nota_estrela));
            itemHolder.txtkminforma = ((TextView) view.findViewById(R.id.textView));
            itemHolder.corfundo = ((RelativeLayout)view.findViewById(R.id.layoutresposta_pesquisa));

            view.setTag(itemHolder);
        } else {
            itemHolder = (ItemSuporte) view.getTag();
        }

        ItemListaPesquisaResp item = itens.get(position);
        if (item.toString() == "Anuncios de trabalho") {
            itemHolder.txtTitle = ((TextView) view.findViewById(R.id.txtnome_resp_pesquisa));
        } else {
            if (item.getnome().equals("Buscar")) {

                itemHolder.txtTrabalho.setVisibility(View.GONE);
                itemHolder.txtkm.setVisibility(View.GONE);
                itemHolder.imgIcon.setVisibility(View.GONE);
                itemHolder.imgnota.setVisibility(View.GONE);
                itemHolder.txtkminforma.setVisibility(View.GONE);
                itemHolder.txtTitle.setText("Mais");
            }
            else {
                itemHolder.txtTrabalho.setVisibility(View.VISIBLE);
                itemHolder.txtkm.setVisibility(View.VISIBLE);
                itemHolder.imgIcon.setVisibility(View.VISIBLE);
                itemHolder.imgnota.setVisibility(View.VISIBLE);
                itemHolder.txtkminforma.setVisibility(View.VISIBLE);
                itemHolder.txtTitle.setText(item.getnome());
                itemHolder.txtTrabalho.setText(item.getprofissao());
                itemHolder.txtkm.setText(item.getkm());
                itemHolder.txtkminforma.setText("km");
                if (item.getfoto().equals("")) {

                } else {
                    if (item.getfoto().equals(" ")){

                    }else {
                        Picasso.with(context).load(item.getfoto()).into(itemHolder.imgIcon);  // esta dando erro aqui!
                    }
                }
                itemHolder.imgnota.setImageDrawable(item.getnota());
            }

        }
        return view;
    }

    private class ItemSuporte {

        ImageView imgnota, buscarimg,imgIcon;
        TextView txtTitle, txtkminforma;
        public TextView txtkm;
        public TextView txtTrabalho;
        TextView buscar;
        RelativeLayout corfundo;
    }

}

Whatever comes back to me on Logcat is

Answer 1

As you say in the error itself, its variable context is null, and in fact you are not setting any value for it, which in case should be done in the constructor.

Modify it to:

public AdapterListPesquisaResp(Context context, ArrayList<ItemListaPesquisaResp> itens) {
    this.itens = itens;
    this.context = context;
    mInflater = LayoutInflater.from(context);
}
