Volley, SwipeToRefresh and notifyDataSetChanged() not working

I fetch the data from my Server with Volley and put the data inside a GridView.
Now when I use swipeToRefresh, it should load the new/changed data. For this I tried everything but nothing worked.
First my code:
MainActivity.java
public class MainActivity extends AppCompatActivity {
List<getter_setter> list = new ArrayList<>();
grid_adapter grid_adapter;
GridView gridView;
SwipeRefreshLayout swipeRefreshLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
swipeRefreshLayout = findViewById(R.id.swipeRefresh);
getData();
gridView = findViewById(R.id.gridView);
grid_adapter = new grid_adapter(getApplicationContext(),list);
gridView.setAdapter(grid_adapter);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
getData();
grid_adapter.update(list);
swipeRefreshLayout.setRefreshing(false);
}
});
}
public void getData(){
final String url = "http://*.**.***.***/";
final RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("userdata");
for(int i = 0; i < jsonArray.length(); i++){
JSONObject jsonObject = jsonArray.getJSONObject(i);
String NAME = jsonObject.getString("NAME");
String BILD = jsonObject.getString("VORSCHAUBILD");
getter_setter getter_setter = new getter_setter(NAME,"",BILD);
list.add(getter_setter);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
requestQueue.add(jsonObjectRequest);
}
}
And the BaseAdapter
public class grid_adapter extends BaseAdapter{
Context context;
List<getter_setter> list;
public grid_adapter(Context context, List<getter_setter> list) {
this.context = context;
this.list = list;
}
#Override
public int getCount() {
return list.size();
}
#Override
public Object getItem(int i) {
return list.get(i);
}
#Override
public long getItemId(int i) {
return 0;
}
public void update(List<getter_setter> listUpdate){
this.list.addAll(listUpdate);
notifyDataSetChanged();
}
#Override
public View getView(int i, View view, ViewGroup viewGroup) {
View gridView = view;
if(view == null){
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
gridView = inflater.inflate(R.layout.grid_design,null);
}
final getter_setter getter = list.get(i);
TextView name = gridView.findViewById(R.id.NAME);
final ImageView bild = gridView.findViewById(R.id.bild);
name.setText(getter.getNAME());
Picasso.with(context).load(getter.getVORSCHAUBILD()).into(bild);
return gridView;
}
}

Check The Updated Listener
Explanation-:
Since You Are Passing Reference Of Your List Into RecyclerView Hence Updating List In The Activity Will Update The List In Adapter Automatically
No Need To Call update Method
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
list.clear(); // Clean The List Before Adding Updated Data
grid_adapter.notifyDataSetChanged();
getData();
grid_adapter.notifyDataSetChanged();
swipeRefreshLayout.setRefreshing(false);
}
});

Parsing JSON news in Android

I am trying to display news received from a json data source. But, I am getting an error when I try to parse the data.
The json data looks something like this:
click here to view
Here is the class I wrote for parsing :
public class FragmentUniversityNews extends Fragment {
private String TAG = FragmentUniversityNews.class.getSimpleName();
private static final String endpoint = "https://api.myjson.com/bins/18smd";
private static final String endpoint_final = "http://srm-news-bot.herokuapp.com";
private SwipeRefreshLayout swipeRefreshLayout;
private SimpleStringRecyclerViewAdapter mAdapter;
private JsonObjectRequest req;
String[] titles = new String[15];
String[] snips = new String[15];
String[] links = new String[15];
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
RecyclerView recyclerView;
View rootView = inflater.inflate(R.layout.fragment_university_news, container, false);
//((ActivityMain) getActivity()).showFloatingActionButton();
recyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view_university);
swipeRefreshLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.swipe_refresh_layout);
swipeRefreshLayout.setColorSchemeResources(R.color.red500, R.color.black, R.color.google_blue_900);
mAdapter = new SimpleStringRecyclerViewAdapter(getContext(), titles, snips, links);
// Calling another function which has the details
setupRecyclerView(recyclerView);
// Make it look like something is happening
swipeRefreshLayout.setRefreshing(true);
// Make the request!
makeJSONRequest();
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
// onRefresh action here
swipeRefreshLayout.setRefreshing(true);
makeJSONRequest();
}
});
return rootView;
}
private void setupRecyclerView(RecyclerView recyclerView) {
recyclerView.setLayoutManager(new LinearLayoutManager(recyclerView.getContext()));
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(mAdapter);
}
public void makeJSONRequest() {
req = new JsonObjectRequest(endpoint_final,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
// Getting JSON Array node
JSONArray newsItems = response.getJSONArray("newsItems");
// UI
try {
for (int j = 0; j < newsItems.length(); j++) {
JSONObject newsItem = newsItems.getJSONObject(j);
titles[j] = newsItem.getString("title");
snips[j] = newsItem.getString("snip");
links[j] = newsItem.getString("link");
}
swipeRefreshLayout.setRefreshing(false);
} catch (JSONException e) {
Log.e(TAG, "Json parsing error: " + e.getMessage());
Toast.makeText(getContext(), "JSON Parsing error", Toast.LENGTH_LONG).show();
} mAdapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "Error: " + error.getMessage());
Toast.makeText(getContext(), "Error Receiving News", Toast.LENGTH_LONG).show();
}
});
// Adding request to request queue
InitializeVolley.getInstance().addToRequestQueue(req);
}
public static class SimpleStringRecyclerViewAdapter extends RecyclerView.Adapter<SimpleStringRecyclerViewAdapter.ViewHolder> {
private String[] mTitles, mSnips, mLinks;
private Context mContext;
public static class ViewHolder extends RecyclerView.ViewHolder {
public final View mView;
public final TextView mTextViewTitle, mTextViewSnip;
public ViewHolder(View view) {
super(view);
mView = view;
mTextViewTitle = (TextView) view.findViewById(R.id.univ_news_title);
mTextViewSnip = (TextView) view.findViewById(R.id.univ_news_snip);
}
}
// Constructor
public SimpleStringRecyclerViewAdapter(Context context, String[] Titles, String[] Snips, String[] Links) {
mContext = context;
mTitles = Titles;
mSnips = Snips;
mLinks = Links;
}
public String getTitleAt(int position) {
return mTitles[position];
}
public String getSnipAt(int position) {
return mSnips[position];
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_view_univ, parent, false);
return new ViewHolder(itemView);
}
#Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
holder.mTextViewTitle.setText(getTitleAt(position));
holder.mTextViewSnip.setText(getSnipAt(position));
holder.mView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//startScan();
Context context = v.getContext();
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(mLinks[holder.getAdapterPosition()]));
context.startActivity(intent);
}
});
}
#Override
public int getItemCount() {
return mTitles.length;
}
}
}
The error I am getting in Android Studio is at the line "JSONArray newsItems = response.getJSONArray("newsItems");",
It's saying
Unhandled exception:org.json.JSONException
When I move JSONArray newsItems = response.getJSONArray("newsItems"); in "try" block, it says
`Cannot resolve constructor 'JsonObjectRequest(java.lang.String, anonymous com.android.volley.Response.Listener<org.json.JSONObject>, anonymous com.android.volley.Response.ErrorListener)'`

Isolating just the parsing part out of your code I couldn't reproduce the error, here is my code:
String jsonStr = "";//TODO insert JSON sample from link
JSONObject jsonObj = null;
try {
jsonObj = new JSONObject(jsonStr);
JSONArray newsItems = jsonObj.getJSONArray("newsItems");
for (int j = 0; j < newsItems.length(); j++) {
JSONObject newsItem = newsItems.getJSONObject(j);
Log.d(TAG,
"Title: " +newsItem.getString("title") +
"\nSnip: " + newsItem.getString("snip") +
"\nLink: " +newsItem.getString("link")
);
}
} catch (JSONException e) {
e.printStackTrace();
}
There is either an error while retrieving the content directly as a JSONObject, or anything unrelated to the JSON parsing.
To help you out further it would be great to have an errorlog, as mentioned by Kris Roofe already.

I solved my problem by adding "null" in the JSONObjectRequest function. I didn't understand why.
public void makeJSONRequest() {
req = new JsonObjectRequest(endpoint_final, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());

how to use both Swipe List Adapter and Scroll List Adapter at the listview

I'm developing an android application that have the Swipe List function found Here and now i have add a fast scroll function to the list view that found here
Here is my code :

You need to clear your listblogs list before adding new items. This is why you get duplicated values.
Also you're already adding new items to listblogs in parseJSONResponse() method, so there is no need for listblogs=parseJSONResponse(response); in onResponse() method, while its the same list.
Change your onResponse() method to:
#Override
public void onResponse(JSONArray response) {
listblogs.clear(); // here you clear the old data
parseJSONResponse(response);
mAdapterDashBoard.setBloglist(listblogs);
System.out.println("it worked!!!");
}

Listview items reloaded on fragment

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:
public class TabFragmentComerTiposRestaurante extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
public static int int_items = 2 ;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
/**

*/
View x = inflater.inflate(R.layout.tab_layout_tipo_rte,null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
/**
*Set an Apater for the View Pager
*/
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
/**
* Now , this is a workaround ,
* The setupWithViewPager dose't works without the runnable .
* Maybe a Support Library Bug .
*/
tabLayout.post(new Runnable() {
#Override

tabLayout.setupWithViewPager(viewPager);
}
});
return x;

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. :)
