Why my recyclerview isn't showing any item? - java

I just created my recyclerview to show a cardview when I just filling the required data on AddNewTimerFragment.java. But somehow it wont show the card that contains the data that I've fill in before. I've tried to changes something, but doesn't work.
Code :

Somebody please help me I am Newbie to this.
This is another method of sending data from Adapter to Activity.
Follow these steps carefully:
Create an interface with a method
public interface InterfaceTax {
public void getTaxMoney(int amount);
}
the parameters of the method should contain the data you want to send back to the activity.
Create a variable for that interface in the Adapter and add the interface to the constructor of the Adapter.
private InterfaceTax interfaceT;
public ChannelAdapter(/* other parameters */, InterfaceTax interface) {
interfaceT = interface;
}
Then in onBindViewHolder (or wherever your data is) call the method of the interface and send the data
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int i) {
money = String.valueOf(channel_tMoney.get(i));
interface.getTaxMoney(money);
}
Then in your activity implement the interface and override the method to receive data
public class UserDetailsActivity extends AppCompatActivity implements InterfaceTax {}
#Override
public void getTaxMonney(int data) {
// receive data here
}
In your AddChannel method, replace this line
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney);
with this
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney, this);
This will automatically send the data from the adapter to the activity and you can receive it in the method overridden in the activity.

ItemClickListener not working in Fragment RecyclerView with onclick

I've been following this tutorial: Tutorial
To make a json recyclerviewer with onclick, but i wanted to use Fragments instead of activities.
I've figured everything out until the point of the onClick.
My problem is the setOnItemClickListener is not taking my getActivity()
I've tried so much, but i just cant see the bright light.
If anyone could help me out that would be totally awesome!
Me only real problem is that the getActivity is giving a red line in the:

You cant use NieuwsAdapter.setOnItemClickListener(getActivity()); , unless your activity implements OnItemClickListener interface, but im seeing that your fragment implements OnItemClickListener, so you can use the fragment instead like this :
fNieuwsAdapter.setOnItemClickListener(NieuwsFragment.this);
And by the way, you are sending the data via intent with :
detailIntent.putExtra(EXTRA_URL, clickedItem.getImageUrl());
detailIntent.putExtra(EXTRA_HEADING, clickedItem.getHeading());
detailIntent.putExtra(EXTRA_CONTENT, clickedItem.getContent());
You have to get them with the same parameters (remove the ""):
String imageUrl = intent.getStringExtra(EXTRA_URL);
String creatorName = intent.getStringExtra(EXTRA_HEADING);
String likeCount = intent.getStringExtra(EXTRA_CONTENT);
Hope this helps
change
public NieuwsAdapter(Context context, ArrayList<NieuwsItem> nieuwslist) {
NieuwsContext = context;
NieuwsList = nieuwslist;
}
to
public NieuwsAdapter(Context context, ArrayList<NieuwsItem> nieuwslist, OnItemClickListener mOnClickListener) {
this.NieuwsContext = context;
this.NieuwsList = nieuwslist;
this.NieuwsListener = mOnClickListener;
}
and this
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (NieuwsListener != null) {
int position = getAdapterPosition();
if (position != RecyclerView.NO_POSITION) {
NieuwsListener.onItemClick(position);
}
}
}
});
change to
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
NieuwsListener.onItemClick(int position);
}
});
and then in fragment You can do it like this
fNieuwsAdapter = new NieuwsAdapter(getActivity(), fNieuwsList,new NieuwsAdapter.OnItemClickListener() {
#Override
public void onItemClick(int position)
{
//DoSomethingHere
}
});

Activity Reloads with Previous Selected Data Bug

So i developed an android news app. A spinner item is available on the toolbar and data reloads according to spinner selection. However, when the data reloads, for some of the items, it directly loads the relevant content but for some others, it loads the previously selected spinner data. Current data for the current item only shows after reloading same spinner data using the swipe refresh functionality which i had implemented. I want the correct data relevant to that selection to load the first time itself without having to refresh all the time.
Below is my MainActivity where all these functions are called.

I discovered that from API level 3, one can use the onUserInteraction() on an Activity with a boolean value thereby determining the user's interaction.
Find the documentation in the link below.
http://developer.android.com/reference/android/app/Activity.html#onUserInteraction()
#Override
public void onUserInteraction() {
super.onUserInteraction();
userInteracts = true;
}
The my adjustment goes as thus in the MainActivity.java
mySpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
int check = 0;
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
if (IsInteracting) {
Intent intent = getIntent(); //MainActivity
String itemSelected = mySpinner.getItemAtPosition(mySpinner.getSelectedItemPosition()).toString();
//TODO: DONE
prefManager.spinWriteString(itemSelected);
Toast.makeText(getApplicationContext(), "Constituency News Now Showing", Toast.LENGTH_SHORT).show();
startActivity(intent);
finish();
}

Json data output not updating fragment view

Currently I'm trying solve a issue. When I open my app, it must show the JSON output data, but the JSON take 1 - 2 seconds to finish the loading, and after that, still not updating the fragment view.
What I've tried:
1 - Using notifyDataSetChanged()
2 - Testing the app on real mobile device
3 - Search so much before create this thread.
Nothing helped me at this moment.

Can you help me? I really don't know what I must do to fix this problem and make the system update the view after JSON finish the loading
Solution:
Follow the below steps:
Step1:
Make this: RecyclerViewAdapter recyclerViewAdapter as a Global object so that you can access it throughout the Fragment.
Step2:
Add this line: recyclerviewadapter.notifyDataSetChanged() after the for loop in your onResponse() method.
Try it, Hopefully it should work.
Try to initialize the array list in your fragment where you have declared it
private List<mList> listContact= new ArrayList<>();
and try notifyDataSetChanged(); in your fragment too
Create an instance of your adapter in fragment and
check whether your adapter is null or not.
if(adapter != null){
adapter.notifyDataSetChanged();
} else {
adapter = new Adapter(getContext, listContact);
recyclerView.setAdapter(adapter);
}

Please comment if you have any doubts.
if Somebody looking for same Solution. bellow is my code
public class Search_vender extends AppCompatActivity {
String catname,city;
int catid;
SearchView Vendname;
private Session session;
ListView listview;
SearchAdapter adapter;
ArrayList<Search> vendersearchlist = new ArrayList<Search>();
ArrayList<Search> filteredSearchResults = new ArrayList<Search>();
ProgressDialog progressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search_vender);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
session = new Session(Search_vender.this);
progressDialog = new ProgressDialog(Search_vender.this);
progressDialog.setCancelable(false);
catid = getIntent().getIntExtra("CatId",00);
catname= getIntent().getStringExtra("CatName");
city = session.getUserLocation().get(session.KEY_UCITY);
//Toast.makeText(Search_vender.this,catid + city,Toast.LENGTH_LONG).show();
listview = (ListView) findViewById(R.id.listview);
Vendname = (SearchView) findViewById(R.id.searchitem);
Vendname.setQueryHint("Search "+catname+" in "+city);
Vendname.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
//Toast.makeText(Search_vender.this, String.valueOf(hasFocus),Toast.LENGTH_SHORT).show();
}
});
Vendname.setOnQueryTextListener(new OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
// TODO Auto-generated method stub
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
if(newText.length() > 2){
listview.setVisibility(View.VISIBLE);
GetDataVender gv = (GetDataVender) new GetDataVender().execute(newText);
}else{
listview.setVisibility(View.INVISIBLE);
}
return false;
}
});
}
public void filterSearchArray(String newText){
String pName;
filteredSearchResults.clear();
for (int i = 0; i < vendersearchlist.size(); i++)
{
pName = vendersearchlist.get(i).getVname().toLowerCase();
if ( pName.contains(newText.toLowerCase()))
{
filteredSearchResults.add(vendersearchlist.get(i));
}
}
}
class GetDataVender extends AsyncTask<String, Void, String>{
String textsearch;
#Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog.setMessage("Loading Please Wait...");
showDialog();
}
#Override
protected String doInBackground(String... strings) {
OkHttpClient client = new OkHttpClient();
okhttp3.Request request = new okhttp3.Request.Builder()
.url("http://api.zesteve.com/autosearch.php?city="+city+"&catid="+catid+"&name="+strings[0])
.build();
this.textsearch = strings[0];
try {
Response response = client.newCall(request).execute();
JSONArray array = new JSONArray(response.body().string());
for (int i=0; i<array.length(); i++){
JSONObject object =array.getJSONObject(i);
Search catagory = new Search(object.getInt("id"),
object.getString("name"));
vendersearchlist.add(catagory);
}
}catch (IOException e){
e.printStackTrace();
} catch (JSONException e) {
System.out.println("End of Catagory");
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if(result != null && result.equalsIgnoreCase("Exception Caught")){
Toast.makeText(Search_vender.this, "Unable to connect to server,please try later", Toast.LENGTH_LONG).show();
hideDialog();
}else{
filterSearchArray(textsearch);
listview.setAdapter(new SearchAdapter(Search_vender.this,filteredSearchResults));
hideDialog();
}
//hideDialog();
//adapter.notifyDataSetChanged();
}
}
private void showDialog() {
if (!progressDialog.isShowing())
progressDialog.show();
}
private void hideDialog() {
if (progressDialog.isShowing())
progressDialog.dismiss();
}
#Override
public boolean onSupportNavigateUp() {
onBackPressed();
return true;
}
}
it works when user stat search from second character.
