android - 我的项目中的 Json 解析错误

转载作者：太空宇宙更新时间：2023-11-03 12:35:15

我在 android 中开发一个项目，该项目使用 json 从 web 服务获取数据并显示在 ListView 中。

我解析了数据，并在模拟器中运行应用程序时强制关闭。

我做错了什么？更正将不胜感激。

这是我的完整代码

It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of &amp;quot;de Finibus Bonorum et Malorum&amp;quot; (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, &amp;quot;Lorem ipsum dolor sit amet..&amp;quot;, comes from a line in section 1.10.32.&lt;\/p&gt;\r\n\r\n&lt;p&gt;The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from &amp;quot;de Finibus Bonorum et Malorum&amp;quot; by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H.

最佳答案

您的 JSON 文件附近有错误

"shop_prdt_images": "1""shop_prdt_clicks": "13",

应该是

"shop_prdt_images": "1",
"shop_prdt_clicks": "13",
