嘿所以我没有收到错误，但我的所有日志都被启动，除了HttpResponse之后不确定原因，并且在服务器端我没有看到POST的任何活动......

不确定我做错了什么，我尝试了各种各样的事情并试图寻找不同的方法去做这个并且没有一个有用......也许它比我看到的更简单...问题我认为这个班级属于私人班级。
答案 0 :(得分：1)
我没有详细阅读您的代码，但我怀疑这是一个强有力的贡献者：
HttpPost httppost = new HttpPost("http://127.0.0.1:3000/wardrobe");
如果您正在使用模拟器，则可能更有可能要连接到“10.0.2.2”。这是：
主机环回接口的特殊别名（即您的主机上的127.0.0.1） 开发机器）
