【问题描述】：

我的问题是当我单击 SearchView 搜索项目时我有 arrayList，例如当我写百事可乐时系统显示消息不幸的是，您的应用程序已停止。

这是代码错误

            ImageLoader.getInstance().displayImage(ittList.get(position).getPic(), holder.ivPic1, new ImageLoadingListener()

这是错误信息

【问题讨论】：

这意味着您的数组大小小于您推送的元素数量。所以修复它

【解决方案1】：

你得到的错误正是它所说的，列表的大小是 3，当没有第三个元素时你试图获取第三个元素。要解决此问题，请执行

   ImageLoader.getInstance().displayImage(ittList.get(position-1).getPic(), holder.ivPic1, new ImageLoadingListener()

这将得到它之前的元素，这可能是你想要的。请记住，它从 0 开始作为索引，而不是 1。所以这三个元素在索引 0、1 和 2 中。
