java - picasso 加载重复图像

Question

我已经搜索过但找不到与我遇到的这个问题有任何关系，我将图像加载到多个 GridView 中，每个 GridView 都在一个选项卡式页面 View 中。性能很好，但是任何包含大量图像并需要滚动加载的图像的 GridView 都是不正确的，它会复制图像并将它们加载到错误的位置。下面是我用于 GridView 的适配器之一:

 public class PcAdapter extends BaseAdapter {
    private Context context;

    private Integer[] imageIds = {
            R.drawable.pcserioussam, R.drawable.pc_trinetwo,
            R.drawable.pc_leftfordead, R.drawable.pc_dungeondefenders,
            R.drawable.pc_portaltwo, R.drawable.pc_spaz,
            R.drawable.pc_laracroftattoo, R.drawable.pc_goatsim,
            R.drawable.pc_deadblock, R.drawable.pc_dynasty,
            R.drawable.pc_minecraft, R.drawable.pc_kanelynch,
            R.drawable.pc_toy, R.drawable.pc_awesomenauts,
            R.drawable.pc_bioniccomm, R.drawable.pc_fastandfurious,
            R.drawable.gen_harryone, R.drawable.gen_harrytwo,
            R.drawable.gen_watchmen
    };

    public PcAdapter(Context c) {
        context = c;
    }

    public int getCount() {
        return imageIds.length;
    }

    public Object getItem(int position) {
        return imageIds[position];
    }

    public long getItemId(int position) {
        return 0;
    }

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

        if(view == null){
            iview = new ImageView(context);
            Picasso.with(context).load(imageIds[position]).
                                  placeholder(R.drawable.placeholder).
                                  resize(230, 300).centerInside().into(iview);
        } else {
            iview = (ImageView) view;
        }
        return iview;
    }
}

如有任何帮助，我们将不胜感激

将您的 picasso 代码移出 if 语句。目前它只会在 View 为空时加载新图像？将它放在 if 语句的底部，就在 return 语句之前。
