Question

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();


                        nameValuePairs.add(new BasicNameValuePair(
                                "product_name", product_name));
                        nameValuePairs.add(new BasicNameValuePair("brand",
                                brand_product));
                        nameValuePairs.add(new BasicNameValuePair("reference_price",
                                mrp_product));
                        nameValuePairs.add(new BasicNameValuePair("model",
                                model_product));

                        HttpPost httppost = new HttpPost(
                                "http://10.0.2.2/wic3/wic2/product/doadd");

                        httppost.setEntity(new UrlEncodedFormEntity(
                                nameValuePairs));
                        ResponseHandler<String> responseHandler = new BasicResponseHandler();
                        String response = SignUpActivity.httpclient.execute(
                                httppost, responseHandler);
                        Log.d("response", response);

                        Intent intent = new Intent(ShareProductActivity.this, ShareActivity.class);
                        startActivity(intent);

这给了我一个例外:

05-07 14:56:19.105: D/exception(1137): org.apache.http.conn.HttpHostConnectException: Connection to http://localhost refused

我搜索了这个,每个人都说改变127.0.0.1了10.0.2.2,但我没有使用127.0.0.1 我想问题就在这一步:

String response = SignUpActivity.httpclient.execute(httppost, responseHandler);

Localhost的定义是指托管系统 - 安卓设备本身.除非您尝试联系在Android设备上运行的服务器,否则它将无法为您工作.

遵循那些建议您将127.0.0.1(localhost是其名称)更改为托管模拟器的计算机的转发别名的人的建议.

但请注意,这仅适用于仿真器,而不适用于真实设备.
