The error result is, it is showing null... Which mean no ID that can be obtained.

In your for loop you are not setting id of your List, but your new Story.
Instead of:
for (int i=0; i<storyList.size(); i++) {
Story story = new Story();
story.setIdStory(String.valueOf(i));
}
Use this:
for (int i=0; i<storyList.size(); i++) {
storyList.get(i).setIdStory(String.valueOf(i));
}
Also because your index i=0 starts from zero, you should change for loop index i to start from 1 like this:
for (int i=1; i<=storyList.size(); i++) {
storyList.get(i).setIdStory(String.valueOf(i));
}
Check this main activity:
public class MainActivity extends AppCompatActivity {
private static final String TAG = MainActivity.class.getSimpleName();
// CONNECTION_TIMEOUT and READ_TIMEOUT are in milliseconds
private ArrayList<Story> storyList;
// url to fetch contacts json
private static final String URL = "https://api.kafeinkode.com/childtidur.json";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
storyList = new ArrayList<>();
//Fetch JSON data
fetchData();
}
private void fetchData(){
JsonArrayRequest request = new JsonArrayRequest(URL, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
if (response.length() > 0) {
// Parsing json
List<Story> items = new Gson().fromJson(response.toString(), new TypeToken<List<Story>>() {}.getType());
// adding contacts to contacts list
storyList.clear();
storyList.addAll(items);
for (int i=0; i<storyList.size(); i++) {
storyList.get(i).setIdStory(String.valueOf(i + 1));
}
Log.d("StoryLid: ", storyList.toString());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// error in getting json
Log.e(TAG, "Error: " + error.getMessage());
}
});
VolleyService.getInstance(this).getRequestQueue().add(request);

Assuming you are making an api call:
You should encode parameters in your url.
String query = URLEncoder.encode("phone 6", "utf-8");
String url = "http://myurl.com/search?q=" + query;
The result would be: http://myurl.com/search?q=phone%206

I am working on an instant chat application.My problem is that when i am sending message through my chat application,Message is displayed two times instead of one.Screen shot is given below :

Not able to set action bar title on back press in Android fragments

I am currently working on an Android app. It has a navigation drawer and a few fragments. I want the actionbar title to change depending on the fragment. I have managed to do this. But the problem is when I press the back button the setTitle() method is executed and the title is changed but it does not reflect on the action bar visibly.
EDIT: I found out that the problem was with the navigation drawer opening and closing. So I removed the changing title part from the ondraweropened() and ondrawerclosed(). It solved the current problem. But I want the name to change on opening and retain the current fragment name on closing. Can anyone help me on that?

Try this !.
//on home activity
public ActionBar getsupportactionbar() {
ActionBar mActionBar = getSupportActionBar();
return mActionBar;
}
On your fragments :
ActionBar mActionBar = ((HomeActivity) getActivity()).getsupportactionbar();
if(mActionBar !=null)
mActionBar .setTitle(R.string.dest);
or may be you need to settitle on OnactivityCreated.
