我需要在listview中显示一些记录，但是当我调用服务时，它会在adapter中出错。那么你能告诉我如何更正它吗？我在USERNAME中得到了Arrayindexoutofbound。我也检查了主要活动，但没有任何问题。这个代码普遍有效。但是现在它提出了问题....

答案 0 :(得分：1)
您确定Activityname和Username的大小相同吗？似乎Activityname.length＆gt; Username.length
编辑：在构造函数中添加它以检查数组大小
Log.d("TEST", "Activityname size = " + Activityname.length );
Log.d("TEST", "UserName size = " + UserName.length );
Log.d("TEST", "PlayedDate size = " + PlayedDate.length );
Log.d("TEST", "UserComment size = " + UserComment.length );
Log.d("TEST", "Score size = " + Score.length );
EDIT2：不要这么肯定！
根据Android documentation，如果集合的大小大于参数数组，则collection.toArray（Object []）方法将创建一个新数组。因此，str_arr_ActivityName和str_arr_UserName的大小可能与ActivityName.size（）不同。
答案 1 :(得分：0)
它告诉您正在尝试访问其范围之外的数组。
具体来说，这里：UserName[position]。正如TeddyBearFr所述，此处的位置大于或等于UserName.length。
你必须弄明白，你遇到了这个问题。
此外，您确实需要稍微清理一下代码：
Log，它将封装所有这些变量：scoreId，activityName，userName等等......然后，您的适配器将只读取一个数组Log s。Ok时您正在做的事情应该在后台线程中完成，因此请尝试使用AsyncTask。
