毕加索在BaseAdapter中加载图片的速度非常慢

Question

我在新游戏中实现了Facebook登录，可以挑战朋友。

除了任何可靠的上传用户个人资料图像的方法都很慢之外，一切都可以完美地工作。

我尝试了不同的方法，但最后我离开了受信任的毕加索，但问题仍然存在。

我注意到该问题与以下事实完全相关：我通过了图像链接的“图形”，该图像在加载时比常规图像链接花费了我更多的时间。

也许问题可能也与适配器的类型有关，我使用BaseAdapter加载了朋友列表或分数列表：

public class ScoreAdapter extends BaseAdapter {

    private Context context;
    private ArrayList<Punteggio> ListPunteggi;

    int count;
    View row = null;
    ScoreAdapter adapter = this;

    // Constructor de dos par?metros
    public ScoreAdapter(Context context, ArrayList<Punteggio> ListPunteggi) {
        super();
        this.context = context;
        this.ListPunteggi = ListPunteggi;

    }

    // Obetenemos la cantidad de im?genes
    @Override
    public int getCount() {
        return ListPunteggi.size();
    }

    // Obtenemos el objeto a partir de su posici?n
    @Override
    public Object getItem(int position) {
        return ListPunteggi.get(position);
    }

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

    // Generamos la vista
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {

        final GridHolder holder;
        if (convertView == null) {
            LayoutInflater layoutInflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            row = layoutInflater.inflate(R.layout.item_score, parent, false);
            holder = new GridHolder(row);
            holder.link_img = (ImageView) row.findViewById(R.id.link_img);
            holder.nickname = (TextView) row.findViewById(R.id.nickname);
            holder.posizione = (TextView) row.findViewById(R.id.posizione);
            holder.punti = (TextView) row.findViewById(R.id.punti);
            holder.livello = (TextView) row.findViewById(R.id.livello);


            holder.nickname.setTypeface(null, Typeface.BOLD);
            holder.nickname.setTextColor(Color.BLACK);
            holder.nickname.setShadowLayer(20, 0, 0, Color.WHITE);
            holder.nickname.setPadding(0,10,0,0);

            holder.posizione.setTypeface(null, Typeface.BOLD);
            holder.posizione.setTextColor(Color.BLACK);
            holder.posizione.setShadowLayer(20, 0, 0, Color.WHITE);
            holder.posizione.setPadding(0,10,0,0);

            holder.punti.setTypeface(null, Typeface.BOLD);
            holder.punti.setTextColor(Color.BLACK);
            holder.punti.setShadowLayer(20, 0, 0, Color.WHITE);
            holder.punti.setPadding(0,10,0,0);

            holder.livello.setTypeface(null, Typeface.BOLD);
            holder.livello.setTextColor(Color.BLACK);
            holder.livello.setShadowLayer(20, 0, 0, Color.WHITE);
            holder.livello.setPadding(0,10,0,0);



            row.setTag(holder);
        } else {
            row = convertView;
            holder = (GridHolder) row.getTag();
            holder.progressBar = (ProgressBar) row
                    .findViewById(R.id.progressBar1);

            holder.progressBar.setVisibility(View.VISIBLE);
        }

        adapter.notifyDataSetChanged();



        // Setto le TextView
        holder.nickname.setText((ListPunteggi.get(position).getNome()));
        holder.livello.setText("Livello :"+ListPunteggi.get(position).getLivello());
        holder.posizione.setText(ListPunteggi.get(position).getPosizione());
        holder.punti.setText(ListPunteggi.get(position).getPunti()+" punti");

        Picasso.with(context)
                .load((ListPunteggi.get(position).getUrl()))
                .placeholder(R.drawable.user)
                .error(R.drawable.user)
                .centerCrop()
               // .fit()
                .resize(150, 150)
                .noFade()
                .transform(new CircleTransform())

                        }
                    }
                });
        return row;
    }
