我正在使用picasso将服务器中的图像加载到列表视图项,如下所示:

public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View participantView;
    if(convertView == null) {
        participantView = inflater.inflate(R.layout.participant_item, parent, false);
    } else {
        participantView = convertView;
    }

    TextView textView = (TextView) participantView.findViewById(R.id.participantName);
    textView.setText(getItem(position).getName());
    ImageView imageView = (ImageView) participantView.findViewById(R.id.participantImage);
    String profilePic = getItem(position).getProfilePic();

    if(!profilePic.equals("None")) {
        Log.d("tom.debug", "creating picture for user: " + getItem(position).getName());
        Picasso.with(this.context)
            .load(urlToProfilePics + profilePic)
            .placeholder(R.drawable.sample_0)
            .resize(52, 52)
            .into(imageView);
    } else {
        //load the place holder into the image view
        Picasso.with(this.context).load(R.drawable.sample_0);
    } …
