Question

为什么getView方法只调用一次？没有回报？

这是我的代码

public class GridViewAdapter extends BaseAdapter {

Context mContext;
ArrayList<String> list;

GridViewAdapter(Context context,ArrayList<String> list){
    this.mContext = context;
    this.list = new ArrayList<>(list);
}

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

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

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    ImageView view = (ImageView) convertView;

    if(view==null){
        view = new ImageView(mContext);
    }
    Picasso.with(mContext).load(String.valueOf(list.get(position))).resize(360, 512).into(view);
    return view;
}

}

注意：传递的arrayList的大小是20！所以它不是空列表！

尝试扩展

ArrayAdapter<String>

CustomAdapter / getView（）只调用一次？
