I have 2 fragment( Fragment A and fragment B) with functions to load data using .json.
When I click fragment A, the data will load, and when I click fragment B the data will load too.
When I click fragment A another time, the data is reloaded and duplicated (appended with the data from the first click).
How to stop loading data if data is already loaded?

here my fragment code

Just wrap your movieRequest with
if(movieList.isEmpty()){
JsonArrayRequest movieReq = new JsonArrayRequest(url, ... ETC...
// etc
}
But remember that with this approach your data will not update if it is changed on server, to make it updatable you must clear movieList before filling it every time instead:
movieList.clear();

I display pictures from moviesdb using volley in a gridview. The next step is have that gridview in the landscape mode too. So my logic behind this,is to store the list that contains the data as key value pair inside the onSaveInstantState method as:
#Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putParcelableArrayList("movies", moviesList);
outState.putStringArrayList("images", images);
Log.v("TAG","list size:" + moviesList.size());
}
The log output gives me a size of 20 which is correct. However when I am using the debugger, the line
outState.putParcelableArrayList("movies", moviesList);
gives me an empty bundle. That's very strange! The images list works fine,and can see what's in there. Any ideas what is wrong?
Here is my code.
public class MainFragment extends Fragment {
String BASE_URL = "http://api.themoviedb.org/3/discover/movie?api_key=my_key";

// Required empty public constructor

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(savedInstanceState != null) {
moviesList = savedInstanceState.getParcelableArrayList("movies");

}else{
moviesList = new ArrayList<>();
images = new ArrayList<>();
movieAdapter = new MovieAdapter(getActivity());
updateMovies();

gridview = (GridView) rootView.findViewById(R.id.gridview);
int ot = getResources().getConfiguration().orientation;
gridview.setNumColumns(ot == Configuration.ORIENTATION_LANDSCAPE ? 3 : 2);
gridview.setAdapter(movieAdapter);
return rootView;
}
private void updateMovies(){
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.GET,
BASE_URL,
new Response.Listener<JSONObject>() {
#Override

It throws the following exception:
Attempt to invoke virtual method 'void com.example.qtv.qtvmaterial.adapter.Fragment_Film_Adapter.notifyDataSetChanged()' on a null object reference
at com.example.qtv.qtvmaterial.fragment.FragmentListFilm$1.onResponse(FragmentListFilm.java:110)
at com.example.qtv.qtvmaterial.fragment.FragmentListFilm$1.onResponse(FragmentListFilm.java:71)
Before setting adapter to RecyclerView initialize it:
recycleView.setLayoutManager(new LinearLayoutManager(recycleView.getContext()));
adapter = new Fragment_Film_Adapter(inforFilms);
recycleView.setAdapter(adapter);
In my app there is a fragment class (TabFragmentComerTiposRestaurante). It has also two tab fragments in it (Case 0: PrimaryFragmentComerTiposRestaurante, Case 1: SocialFragmentComerTiposRestaurante).
On both fragment classes there is a listview. When clicking on an item from this list, another fragment class is shown (PrimaryFragmentComer.
Shorty this the schema:
TabFragmentComerTiposRestaurante(#F1)
-[PrimaryFragmenComerTiposRestaurante](#F11)--[PrimaryFragmentComer](#F111)
-[SocialFragmentComerTiposRestaurante](#F12)--[SocialFragmentComer](#F121)
The issue I need to solve is the following:
If at (#F111) or at (#F121) the users click on the back button, then the listview items from #F11 and #F12 are loaded again. That means, if on the first #F11 call there is an item called "Cocina americana", then going back from #F111 to #F11 or going back from #F121 to #F12, there are now two equal items: First row=Cocina americana, Second row=Cocina americana. And that happens every time the user goes from #F11 or #F12 to #F111 or #F112.
Here you can find the code for
F1:

As mentioned in the comment,
Data is being readded to tipoRestauranteList in your onResponse() method so to avoid that write tipoRestauranteList.clear() after hidePDialog().
Same will be happening in your #F12. Doing this you can rectify the same. :)
For some reason when the listview in my fragment is loaded it gets cut off at the first row however the same code is used in other listfragments in my app and those are fine ???...
Here is my xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#eeeeee">
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:divider="#eeeeee"
android:dividerHeight="8dp"
android:listSelector="#drawable/list_row_selector"
/>
</LinearLayout>
and here is the fragment class .. I dont the fault lies with the adapter class as I am using that in the other fragments that are working.
public class TabTwoFragment extends ListFragment {
private static final String TAG = AccommodationFragment.class.getSimpleName();
// Movies json url
private static final String url = "http://api.mywebsite.com/json.php";
private ProgressDialog pDialog;
private List<Movie> movieList = new ArrayList<Movie>();
private ListView listView;
private CustomListAdapter adapter;
private View mheaderView;
//private TextView txtFragmentone;
public static TabTwoFragment newInstance() {
Bundle bundle = new Bundle();
TabTwoFragment fragment = new TabTwoFragment();
fragment.setArguments(bundle);
return fragment;
}
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.accommodation_fragment, container, false);
rootView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT ));
listView = (ListView) getActivity().findViewById(android.R.id.list);
adapter = new CustomListAdapter(getActivity(), movieList);
setListAdapter(adapter);
mheaderView = inflater.inflate(R.layout.list_header, null);
pDialog = new ProgressDialog(getActivity());
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
// Creating volley request obj
JsonArrayRequest movieReq = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
Movie movie = new Movie();
movie.setTitle(obj.getString("title"));
movie.setThumbnailUrl(obj.getString("image"));
movie.seturl(obj.getString("url"));
/*movie.setRating(((Number) obj.get("rating"))
.doubleValue());*/
movie.setYear(obj.getString("releaseYear"));
// Genre is json array
JSONArray genreArry = obj.getJSONArray("genre");
ArrayList<String> genre = new ArrayList<String>();
for (int j = 0; j < genreArry.length(); j++) {
genre.add((String) genreArry.get(j));
}
movie.setGenre(genre);
// adding movie to movies array
movieList.add(movie);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes

}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
/* if (mheaderView != null) listView.addHeaderView(mheaderView);*/
// Don't forget to now call setListAdapter()
this.setListAdapter(adapter);
setHasOptionsMenu(true);
}
#Override
public void onListItemClick(ListView l, View v, int position, long id) {
Movie m= movieList.get(position);
String yourURL = m.geturl();
MyDetailFragment myDetailFragment = new MyDetailFragment();
Bundle args = new Bundle();
args.putString("YourKey", yourURL);
myDetailFragment.setArguments(args);
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, myDetailFragment).addToBackStack(null).commit();
}
I have no idea why it is cutting off my listview and I really can't find a solution on my own.... so any help would be great!
