推荐答案

不确定你的 mysql() 方法和错误处理的巨大缺失，但你确定你的项目在你的 AndroidManifest.xml 中允许 INTERNET 权限文件?在我看来，您的 getInt 不是 int.

Not sure about your mysql() method and the huge lack of error handling, but are you sure that your project has allowed for INTERNET permissions in your AndroidManifest.xml file? Sounds to me like your getInt is not an int.
