2、这种也不行：

try {

				Log.v("Sys", "111111");

				List<NameValuePair> params = new ArrayList<NameValuePair>();

				params.add(new BasicNameValuePair("username", loginname));

				params.add(new BasicNameValuePair("password", loginpwd));

				params.add(new BasicNameValuePair("flag", "0"));

				httpRequest.setEntity(new UrlEncodedFormEntity(params,

						HTTP.UTF_8));

				HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);

				if(httpResponse.getStatusLine().getStatusCode()==200)  {               

	  

					msgStr = EntityUtils.toString(httpResponse.getEntity());

					if (msgStr.equals("登录成功")) {

						Toast.makeText(LoginView01.this, "登录成功！", Toast.LENGTH_SHORT)

								.show();

						Log.v("Sys", "登录成功:");

						gotoMainView();

					} else {

						Log.v("Sys", "登录失败:" + msgStr);

						Toast.makeText(LoginView01.this, "登录失败", Toast.LENGTH_SHORT).show();

					}

				}

				else{

					Log.v("Sys", "登录失败:" + msgStr);

					Toast.makeText(LoginView01.this, "登录失败", Toast.LENGTH_SHORT).show();

				}

			} catch (ClientProtocolException e) {

				e.printStackTrace();

			} catch (UnsupportedEncodingException e) {

				e.printStackTrace();

			} catch (IOException e) {

				e.printStackTrace();

			}
