public static String huodongzan_post(String url, String login_user,
   String now_userid, String id, String action, String type) throws JSONException, ParseException, IOException {    //都是自己定义的
  // TODO Auto-generated method stub
  String back = Constz.back;
  url = Constz.IPAddress + url;

// System.out.println("发布活动网址 url " + url);

  HttpClient httpClient = new DefaultHttpClient();
  HttpPost httpPost = new HttpPost(url);
  JSONObject jsonObject = new JSONObject();
  jsonObject.put("login_user", login_user);
  jsonObject.put("now_userid", now_userid);
  jsonObject.put("action", action);
  jsonObject.put("id", id);
  jsonObject.put("type", type);

  List<BasicNameValuePair> listPairs = new ArrayList<BasicNameValuePair>();

listPairs.add(new BasicNameValuePair("json", jsonObject.toString()));

  System.out.println("listPairs 活动点赞 " + listPairs.toString());
  httpPost.setEntity(new UrlEncodedFormEntity(listPairs, "utf-8"));
  HttpResponse response = httpClient.execute(httpPost);

int code = response.getStatusLine().getStatusCode();
System.out.println("code 活动点赞 " + code);

  if (code == 200) {
   HttpEntity entity = response.getEntity();
   back = EntityUtils.toString(entity, "utf-8");
    System.out.println("活动点赞    " + back);
  }
  return back;

}
}

PS: 然后在需要用到的activity页面写入这个类的方法名，并传递相应的参数
