您不应该在主线程中调用网络连接。尝试使用 AsyncTask 以在后台线程上运行网络操作。

像这样试试

Class Login extends Activity
{
   protected void onCreate(Bundle savedInstanceState) 
   {
     button2.setOnClickListener(new OnClickListener() 
     {
       public void onClick(View arg0) 
       {
         Task t = new Task();
         t.execute();
       }
   }
   class Task extends AsyncTask<ArgType,ArgType,ArgType>
   {
     protected type doInBackground(ArgType... urls) 
     {
       try
       {
          //initiate httpconnection and get result
       }
       catch
       {
       }
     }
     protected void onPostExecute(ArgType result) 
     {
       //update some view or do some thing when background thread work is done
     }
   }
}

或者您可以参考http://www.android-ever.com/2012/10/android-asynctask-example.html了解更多关于 AsyncTask 的信息。
