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：
public class MainActivity extends Activity {

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
在Handler handler=new Handler(){...}; 前加上Looper.prepare();结束之后加上Looper.loop();
或者直接Handler handler = new Handler(Looper.getMainLooper()){...};
不知道你怎么抓的网页数据，一般用不着这么多post,还有就是你这个cookie设置的似乎没什么意义啊。
当然最重要的还是对于网站登录过程本身的分析，这个准确的话也就搞定大半了。
Httpclient也不怎么好使，上okhttp吧，搞个工具类，这些操作都写进去，用接口完成回调，要不这activity到最后自己都看不明白了..
