推荐答案

您可以与您的结构的XML即对象的数组，每个有两个字段，然后将其转换为字符串，
作为一个例子，

You can make an xml with your structure i.e an array of objects each having two fields then convert that to string as, As an example,

       String  input = String.format("<Request><Data><Id>%s</Id></Data> 
       </Request>",studentIdSelected);

然后调用此方法输入和URL作为参数张贴您的数据，

Then call this method with input and url as parameters for posting your data,

       public static String retriver(String Url, String input) {

    String responseString = null;
    StringEntity stringEntity;
    HttpPost postRequest = new HttpPost(Url);
    try {

        Log.e("string is", input + "\n" + Url);
        stringEntity = new StringEntity(input, "UTF-8");
        stringEntity.setContentType("application/atom+xml");

        postRequest.setEntity(stringEntity);
        Log.v("Post", "Posted");
        HttpClient httpclient = new DefaultHttpClient();
        HttpResponse response = httpclient.execute(postRequest);  
        HttpEntity getResponseEntity = response.getEntity();

        responseString = EntityUtils.toString(getResponseEntity);

    } catch (Exception e) {
        // TODO: handle exception
        postRequest.abort();
        Log.w("HttpPostRetreiver", "Error for URL " + Url, e);
    }

    return responseString;

}

另外，您可以使用JSON也是如此。

Alternatively you can use json as well.
