看下这个,看有用没

则可以把数据表输出为JSON或者XML格式了.客户端的Android调用: try {
HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams,
TIMEOUT_MILLISEC);
HttpConnectionParams.setSoTimeout(httpParams, TIMEOUT_MILLISEC);
HttpParams p = new BasicHttpParams();
p.setParameter("user", "1");
HttpClient httpclient = new DefaultHttpClient(p);
String url = "http://10.0.2.2:8082/myphp/phpWebservice/webservice1.php?user=1&format=json";
HttpPost httppost = new HttpPost(url);
try {
Log.i(getClass().getSimpleName(), "send task - start");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
2);
nameValuePairs.add(new BasicNameValuePair("user", "1"));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
ResponseHandler<String> responseHandler = new BasicResponseHandler();
String responseBody = httpclient.execute(httppost,
responseHandler);
// 解析JSON返回的 JSONObject json = new JSONObject(responseBody);
JSONArray jArray = json.getJSONArray("posts");
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String, String>>();
for (int i = 0; i < jArray.length(); i++) {
HashMap<String, String> map = new HashMap<String, String>();
JSONObject e = jArray.getJSONObject(i);
String s = e.getString("post");
JSONObject jObject = new JSONObject(s);
map.put("idusers", jObject.getString("idusers"));
map.put("UserName", jObject.getString("UserName"));
map.put("FullName", jObject.getString("FullName"));
mylist.add(map);
}
Toast.makeText(this, responseBody, Toast.LENGTH_LONG).show();
