这是您的数组：您可以根据需要在示例中创建更多数组。
ArrayList<String> contact = new ArrayList<String>();
然后，创建JSONObject类型的JSONcontacts变量以将此数组存储在此对象中
JSonObject JSoncontacts = new JSonObject();
现在，遍历该联系人数组中的所有元素并将其存储在JSONcontacts中
//Loop through array of contacts and put them to a JSoncontact objectfor (int i = 0; i < contact.size(); i++) { try { JSONcontacts.put("Count:" + String.valueOf(i + 1), contact.get(i)); } catch (JSonException e) { e.printStackTrace(); }}假设您创建了许多您可能已经完成的数组，现在您必须将它们全部放入1个JSON中。因此，创建类型为JSONObject（）的EverythingJSON变量
JSonObject EverythingJSON = new JSonObject();
然后将所有联系人数组和其他数组放入其中，就可以按照上述方法遍历它们：
EverythingJSON.put("contact", JSONcontacts);EverythingJSON.put("something", JSONsoemthing);EverythingJSON.put("else", JSONelse);现在，这是将其发送到您的PHP服务器的AsynchTask：
new AsyncTask() { //String responseBody = ""; @SuppressWarnings("unused") protected void onPostExecute(String msg) { //Not Needed } protected Object doInBackground(Object... params) { //Create Array of Post Variabels ArrayList<NamevaluePair> postVars = new ArrayList<NamevaluePair>(); //Add a 1st Post Value called JSON with String value of JSON inside //This is first and last post value sent because server side will depre the JSON and get other vars from it. postVars.add(new BasicNamevaluePair("JSON", EverythingJSON.toString()); //Declare and Initialize Http Clients and Http Posts HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(Config.OnlineAPI); //Format it to be sent try { httppost.setEntity(new UrlEnpredFormEntity(postVars)); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } try { HttpResponse response = httpclient.execute(httppost); String responseBody = EntityUtils.toString(response.getEntity()); } catch (ClientProtocolException e) { e.printStackTrace(); Log.v("MAD", "Error sending... "); } catch (IOException e) { e.printStackTrace(); Log.v("MAD", "Error sending... "); } return null; }}.execute(null, null, null);现在在PHP服务器端，您可以像这样循环遍历此JSON：首先，从POST获取该JSON并将其存储在var中：
//Receive JSON$JSON_Received = $_POST["JSON"];
现在从JSON解码：
//Depre Json$obj = json_depre($JSON_Received, true);
这是遍历联系人数组并从中获取键和值的循环：
foreach ($obj['contact'] as $key => $value) { //echo "<br>------" . $key . " => " . $value;}您可以对发送的其他数组重复此循环：）祝您好运！
