我有一个WCFWebservice，其中发送了一个数据模型，我通过JSon（通过实体框架）在Android中获得了这个数据模型，无论如何，我都可以通过此代码成功地获得JSON，并将所有JSON对象存储在AsyncTas类的JSONArray中，以及：

public class Consume extends AsyncTask<Void, Void, Void> {
            InputStream inputStream = null;
            String result = "";
            private ArrayList<Contact> contacts = new ArrayList<Contact>();
        @Override
            protected Void doInBackground(Void... params) {
                String URL = "http://x.x.x.x/MyWCF/Service1.svc/rest/getContact";
                ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();
                try {
                    HttpClient httpClient = new DefaultHttpClient();
                    HttpPost post = new HttpPost(URL);
                    post.setEntity(new UrlEncodedFormEntity(param));
                    HttpResponse httpResponse = httpClient.execute(post);
                    HttpEntity httpEntity = httpResponse.getEntity();
                    //post.setHeader("content-type", "application/json");
                    inputStream = httpEntity.getContent();
                } catch (UnsupportedEncodingException e1) {
                    Log.e("UnsupportedEncoding", e1.toString());
                    e1.printStackTrace();
                } catch (ClientProtocolException e2) {
                    Log.e("ClientProtocolException", e2.toString());
                    e2.printStackTrace();
                } catch (IllegalStateException e3) {
                    Log.e("IllegalStateException", e3.toString());
                    e3.printStackTrace();
                } catch (IOException e4) {
                    Log.e("IOException", e4.toString());
                    e4.printStackTrace();
                }
                try {
                    BufferedReader bReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
                    StringBuilder sBuilder = new StringBuilder();
                    String line = null;
                    while ((line = bReader.readLine()) != null) {
                        sBuilder.append(line + "\n");
                    }
                    inputStream.close();
                    result = sBuilder.toString();
                } catch (Exception e) {
                    Log.e("StringBuilding", "Error converting result " + e.toString());
                }
                return null;
            }
            @Override
            protected void onPostExecute(Void aVoid) {
                super.onPostExecute(aVoid);
                try {
                    JSONObject object = new JSONObject(result);
                    JSONArray jArray = object.getJSONArray("getContactResult");  //here i create the JsonArray of all JsonObjects
//Here  is the solutions, We make a list of out Contact and make it as down
            List<Contact> contacts;
           Type listType = new TypeToken<List<Contact>>() {
           }.getType();
           contacts= new Gson().fromJson(String.valueOf(jArray), listType);
//And here solution is ended !
               } catch (JSONException e) {
                    e.printStackTrace();
                }
            }

我在android中创建了一个联系人class，代码如下：

public class Contact {
 @SerializedName("name")
    private String name;
        @SerializedName("lastName")
        private String lastName;
        @SerializedName("phoneNumber")
        private String phoneNumber;
        @SerializedName("latitude")
        private String latitude;
        @SerializedName("longitude")
        private String longitude;
        public void setName(String name) {
            this.name = name;
        }
        public String getName() {
            return name;
        }
        public void setLastName(String lastName) {
            this.lastName = lastName;
        }
        public String getLastName() {
            return lastName;
        }
        public void setPhoneNumber(String phoneNumber) {
            this.phoneNumber = phoneNumber;
        }
        public String getPhoneNumber() {
            return phoneNumber;
        }
        public void setLatitude(String latitude) {
            this.latitude = latitude;
        }
        public String getLatitude() {
            return latitude;
        }
    public void setLongitude(String longitude) {
        this.longitude = longitude;
    }
    public String getLongitude() {
        return longitude;
    }
}

我用老方法解析这个JSONArray！用这个方法：

ArrayList<Contact> setFields(JSONArray jsonArray) {
        ArrayList<Contact> contacts = new ArrayList<Contact>();
            for(int i=0; i<jsonArray.length(); i++) {
                try {
                    Contact contact = new Contact();
                    JSONObject object = (JSONObject) jsonArray.get(i);
                    contact.setName(object.getString("name"));
                    contact.setLastName(object.getString("lastName"));
                    contact.setPhoneNumber(object.getString("phoneNumber"));
                    contact.setLatitude(object.getString("latitude"));
                    contact.setLongitude(object.getString("longitude"));
                    contacts.add(contact);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            return contacts;
        }

它工作，但我不想处理和解析JSONArray的这种老方法，并希望使用GSON代替，任何人都可以帮助我与这个例子？这里是我的JSONArray和JSON对象：

{
  "getContactResult": [
    {
      "id": 2041,
      "lastName": "xxxx",
      "latitude": xxx,
      "longitude": xxx,
      "name": "xxxx",
      "phoneNumber": "xxxx"
    }
  ]
}

谢谢
