请帮助我。提前谢谢。看起来您的服务器没有JSON结构。添加一个
System.out.println（json）在json=sb.toString（）行之后以查看实际获得的内容。java.lang.String类型的DOCTYPE无法转换为JSONArray；
它说，响应字符串不是json格式，而是像Tom说的html
is.close();
json = sb.toString();
Log.i(TAG, json); //add this log
您可以通过Log.i查看真实的josn字符串。
可能这不是你真正的回答参见：
[首先检查字符集的内容类型标题]
我相信您在电话中遇到了问题：
BufferedReader reader=新的BufferedReader（新的InputStreamReader（is，“iso-8859-1”），8
只需记录Mejonzhan提到的最后一个json字符串，以确认它
希望这有帮助。您的请求有误，或者服务器的响应有误。因此“无法解析，谢谢Tom Dignan…我也将发布我的json响应..请参阅我编辑的帖子..谢谢Ridcully…Ridcully我已经发布了我的web服务返回的内容..那么我要做什么来解析呢？？？嗨，Ridcully，我得到的是html格式，请告诉我如何使用json提取数据。你能发布，你实际得到了什么？一般来说，您应该更改服务器端实现，使其返回JSON响应而不是HTML。嗨，Ridcully，我没有在服务器端更改的控制权。请发布您从服务器获得的信息，好吗？指定的json
变量的值。如果JSON结构在那里的某个地方，您可以删除前面和后面的HTML内容。
