尝试使用此函数将名称-值对发布到 php 脚本

public void postData(List nameValuePairs){  
        // Create a new HttpClient and Post Header
        String url = "http://localhost/recieve.php";
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(url);

        try {
            // Add your data
            //List nameValuePairs = new ArrayList(1);
            //nameValuePairs.add(new BasicNameValuePair(a, b));
            //nameValuePairs.add(new BasicNameValuePair("Number", b));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);


        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            // TODO Auto-generated catch block
        }
    }

发布数据使用->

List nameValuePairs = new ArrayList(1);
nameValuePairs.add(new BasicNameValuePair("Number", b))
postData(nameValuePairs);

希望这可以帮助。

创建一个新的项目命名为 myproject，然后创建一个活动类并查看上面的示例代码！
