小白在做一个模拟登录教务系统的app，可是在post上遇到了问题，理想是如果登录成功了就跳转到logi_success的页面，然后将获得的html源码直接贴上（之后json解析），如果失败的话就跳转到login_fault页面，点击“返回”按钮返回到登录页面
然后我现在遇到的问题是：不知道是数据传递的问题还是其他？我点击登录没有反应，logcat也米有错误提示，不知道是不是获取不了数据还是怎样，希望各位大神指点下小白，谢谢
下面贴代码：
MainActivity.java：

点击登录按钮的话logcat只有这些信息

对了，cookie的值不变，我也不知道为什么，反正用httpwatch查看的都是这个值
