我正在使用自定义网格视图。在滚动时加载和改变位置时，孩子们正在重复。以下是代码。

根据计数，我正在改变网格布局的工作。
我使用Universal loader来显示使用网址的图片
imageLoader.displayImage(bitmapBitmaparrayList.get(position), imageView);
答案 0 :(得分：0)
使用Universal Loader，我认为它与this SO question和this SO question相关 我引用（第一个）：
原因是你从convertView参数重用的视图属于Picasso可能已经为另一张图片加载的前一行。
这在使用convertView时才真正有用，如果您刚刚为新布局充气，则不需要它。但您可以随时致电以使代码更容易。
（排在第一位，但你应该阅读它们;））
Picasso有一个CaneclRequest方法，读到Universl Loader，我猜它有类似的东西，而且，看看你是否可以修改你的getView方法，看起来很麻烦。
希望这有帮助！
