Get information from an ObjectJson without Array

I have the class below and I can fetch information from a JSONArray in this format:
{"cliente":[{"id":"1334","nome":"Bruno"}]}
TextView nome_usuario;
private static final String TAG_CLIENTE = "cliente";
private static final String TAG_NOME = "nome";
JSONArray cliente = null;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View grafico = inflater.inflate(R.layout.fragment_fragment_perfil, container, false);
nome_usuario = (TextView ) grafico.findViewById(R.id.txtNome);
new JSONParse().execute();
return grafico;
}
private class JSONParse extends AsyncTask<String, String, JSONObject> {
private ProgressDialog pDialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Atualizando");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected JSONObject doInBackground(String... args) {
JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl("url do json");
return json;
}
#Override
protected void onPostExecute(JSONObject json) {
pDialog.dismiss();
try {
cliente = json.getJSONArray(TAG_CLIENTE);
JSONObject c = cliente.getJSONObject(0);
String nome = c.getString(TAG_NOME);
nome_usuario.setText(nome);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}
But now I would like to work with a json in the following format:
{"name": "Bruno"}
I found a question similar to my How to parse JSON Object Android Studio, but I could not apply it to my example.

Getting information from an JSONObject:
JSONObject aJsonObject = new JSONObject(aJsonResponse);
JSONArray aJsonArray = aJsonObject.getJSONArray("cliente");
for (int i = 0; i < aJsonArray.length(); i++) {
aJsonObject = aJsonArray.getJSONObject(i);
String aId = aJsonObject .getString("id");
String aNome = aJsonObject .getString("nome");
}

Try using this, you should replace aJsonResponse with the response from the server
JSONObject aJsonObject = new JSONObject(aJsonResponse);
String aId = aJsonObject.getString("id");
String aNome = aJsonObject.getString("name");

how to pass id with url while requesting?

loginpage.java this is my activity for login page.
i am using this json for it {"status":"success","msg":"Your are now Login Successfully","user_login_id":2650}.
here i am getting one unique filed (user_login_id) when user log in successfully.it works fine.
after log in i am using Navigationdrawer which is Activity class and it has different types fragment behavior,one of them is HomeFragment which extended with Fragment.
in that HomeFragment class I want to get some json data in List view.for that I have another json file.which has following link like http://sdfkjksd.com/apps/matching?version=apps&user_login_id=2650
public class HomeFragment extends Fragment {
NavDrawerListAdapter adapters;
private ProgressDialog pDialog;
//JSON parser class
JSONParsing jsonParser = new JSONParsing();
String result = "";
List<HashMap<String,String>> aList;
private static final String TAG_USERID="user_login_id";
private static final String MATCH_URL = "http://sdfa.com/apps/matching?version=apps&user_login_id="+TAG_USERID;
JSONArray matching=null;
private static final String TAG_SUCCESS = "status";
private static final String TAG_MATCH="matching";
private static final String TAG_NAME="name";
private static final String TAG_PROFILE="profile_id";
private static final String TAG_IMAGE="image";
private static final String TAG_CAST="cast";
private static final String TAG_AGE="age";
private static final String TAG_LOCATION="location";
private ListView listview;
ArrayAdapter<String> adapter;
public HomeFragment(){}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//String strtext = getArguments().getString("user_login_id");
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
aList = new ArrayList<HashMap<String,String>>();
/* Bundle bundle = this.getArguments();
if(bundle != null){
String i = bundle.getString("user_login_id", TAG_USERID);
}*/
new LoadAlbums().execute();
return rootView;
}
class LoadAlbums extends AsyncTask<String, String, String> {
/**

#Override

super.onPreExecute();

pDialog.setMessage("Loading...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
}
protected String doInBackground(String... args) {
// Building Parameters
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("version", "apps"));
// getting JSON string from URL
String json = jsonParser.makeHttpRequest(MATCH_URL, "POST",
params);
// Check your log cat for JSON reponse
Log.d("Albums JSON: ", "> " + json);
try {
JSONObject Jasonobject = new JSONObject(result);
JSONArray Jarray = Jasonobject.getJSONArray("matching");
if (Jarray != null) {
// looping through All data
for (int i = 0; i < Jarray.length(); i++) {
JSONObject c = Jarray.getJSONObject(i);
// Storing each json item values in variable
String user_name = c.getString(TAG_NAME);

// creating new HashMap

// adding each child node to HashMap key => value
map.put(TAG_NAME,user_name);
map.put(TAG_PROFILE, user_profile);
map.put(TAG_IMAGE, user_image);
map.put(TAG_CAST, user_cast);
map.put(TAG_AGE, user_age);
map.put(TAG_LOCATION, user_location);
// adding HashList to ArrayList
aList.add(map);
}
}else{
Log.d("Albums: ", "null");
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog after getting all albums
pDialog.dismiss();
// updating UI from Background Thread
runOnUiThread(new Runnable() {
public void run() {
/**
* Updating parsed JSON data into ListView
* */
SimpleAdapter adapter = new SimpleAdapter(
getActivity().getBaseContext(), aList,
R.layout.list_item_matchs, new String[] { TAG_NAME,TAG_PROFILE,TAG_IMAGE,TAG_CAST,TAG_AGE,TAG_LOCATION
}, new int[] {
R.id.txtproname,R.id.txtprofileage,R.id.propic,R.id.txtprofilecast,R.id.txtprofileplace});
// updating listview
listview.setAdapter(adapter);
}
});
}
private void runOnUiThread(Runnable runnable) {
// TODO Auto-generated method stub
}
}
}
so the problem is , in that link i am using user_login_id field of login json,,so i want to send or pass that field during requesting with URL..

I just suggest you to use SharedPreference for this. When you get Login response, just parse the JSON and then get log_in_id field value and save it in SharedPreferences, then whenever you want to use this value you can use throughout your application.

you already used the same method in your doInBackground :
here is a suggested edit to prepare it for the next:
add "user_login_id" to params list
change POST to GET if it is so.
protected String doInBackground(String... args) {
// Building Parameters
List params = new ArrayList();
params.add(new BasicNameValuePair("version", "apps"));
// add the user_login_id to params.
params.add(new BasicNameValuePair("user_login_id ", "265"));
// getting JSON string from URL
// I think you are using GET bcz the url shows the parameters.
String json = jsonParser.makeHttpRequest(MATCH_URL, "GET",
params);

android from activity to fragment

I'm new to android. I want to put one of the activity under one of the tab of my app(the tab is fragment) when i paste my code into fragment, there's a lot of error...
There's error in new JSONParse().execute(); It shows that the type JSONParse is not visible.
in this line private class JSONParse extends AsyncTask there's error
showing illegal modifier for the class JSONParse.only public, abstract and final are permitted.
this line pDialog = new ProgressDialog(TabActivityQueue.this); it shows the constructor progressDialog is undefined.
All the variables phonenumber, peoplenumber , remarks, status, table2, url are not resolved as variables.
What should I change? I'm really stuck.
Here's the activity code :
public class MainActivity extends Activity {
ListView list;
TextView number;
TextView info;
TextView remark;
TextView statuss;
Button Btngetdata;

}
});
}
} catch (JSONException e) {

Whereever you have used context as TabActivityQueue.this (or getApplicationCOntext()) change to getActivity() .
Also if some android pre defined method doesn't work try prefix getActivity() like:- getActivity().method();

declare private Activity activity as public Activity activity;

Can't get the string value in Hash Map on List view adapter in Android

I already getting the string value from JSON but it seems to have the problem in Hash map or something, im getting null value on my List adapter. Can anyone help me or tell me if i did something wrong in my code. Thanks in advance.
Here is my code.
The Activity -
public class TestJSON extends Activity{
public static ListView lv;

// Showing progress dialog before sending http request
pDialog = new ProgressDialog(this);
pDialog.setMessage("Please wait..");
pDialog.setIndeterminate(true);
pDialog.setCancelable(false);
pDialog.show();

JSONArray cannot be converted to JSONObject Android

}
When i run the code i get the error JSONArray cannot be converted to JSONObject.
Please help

Because you are getting a JSONArray not a JSONObject, try this:
JSONArray json = jParser.getJSONFromUrl(url_chapters);
and return JSONArray from getJSONFromUrl(String)
and also remove chaps = json.getJSONArray(TAG_CHAPTERS); because your TAG_CHAPTER is not an array.
And in the for loop do
JSONObject c = json.getJSONObject(i);
in place of
JSONObject c = chaps.getJSONObject(i);
Edit
public class Sheria extends SherlockListFragment {
// Progress Dialog
// private ProgressDialog pDialog;
// private View view;
// Creating JSON Parser object
JSONParser jParser = new JSONParser();
ArrayList<HashMap<String, String>> chapterList;
// url to get all products list
