我有代码从android中的联系人发送数据电话。正如我们所知,android 中电话联系人中的许多数据。我有代码可以从电话联系人中获取数据并显示为这样的列表视图
    Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
                int row = cursor.getCount();
                friend_item = new MenuItem [row];
                int i=0;
                while(cursor.moveToNext()){
                    nama = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                    phone = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    friend_item[i] = new MenuItem(nama,phone);
                    i++;
                }
List<NameValuePair> params = new ArrayList<NameValuePair>();
                params.add(new BasicNameValuePair("phone", mPhoneNumber));
                params.add(new BasicNameValuePair("friend", phone));
                // getting JSON string from URL
                JSONObject json = jParser.makeHttpRequest(Constants.url_phone_contact, "POST", params);
                 // Check your log cat for JSON reponse
                Log.d("All Friend: ", json.toString());
                try {                    
                    friend = json.getJSONArray("friend");
                    friend_item = new MenuItem[friend.length()]; 
                     // looping through All Products
                    for (int a = 0; a < friend.length(); a++) {
                    JSONObject c = friend.getJSONObject(i); 
                    //Storing each json item in variable
                    String phone_friend= c.getString(TAG_PHONE);
                    friend_item[i] = new MenuItem(nama, phone_friend);
                     // creating new HashMap
                     HashMap<String, String> map = new HashMap<String, String>();
                     // adding each child node to HashMap key => value
                   map.put("nama", nama);
                   map.put("phone", phone_friend);
                   // adding HashList to ArrayList
                      friendList.add(map);
                   }
              } catch (JSONException e) {
                e.printStackTrace();
              }             
        return null;
        }
在params.add(new BasicNameValuePair("friend", phone));
朋友是数据数组,来自 [phone_contact] 的数组。那么我如何将数据数组和字符串“mPhoneNumber”发送到android中的服务器?谢谢
