Fragment loading data wrong data when I click in RecyclerView item

So I've been trying to fix this issue for so many hours but can't find the cause behind it.
Issue: My app shows data from my API into recyclerView, a standard feature. The issue comes when I use the search function. When I search for something, my search adapter shows the query data but going back to my Main fragment again, the view loader shows content fine but when I click on it, search items are actually being loaded instead.
Check my app to find out what I'm talking about: https://play.google.com/store/apps/details?id=envision.apps.newsextra
To reproduce, search for something, click on any article from search results, then go back and click any article from main feed, search items are actually being loaded instead.
Here's my main fragment:
public class FeedsFragment extends Fragment implements ArticleListener, LocalMessageCallback {
private PullRefreshLayout pullRefreshLayout;
private RecyclerView recyclerView;
private FeedsAdapter adapter;
private View layout;
private ArrayList<Object> data = new ArrayList<>();

How to add a search filter in RecyclerView to filter through parsed JSON data? edited

I am developing an android app which shows a list of countries affected by Coronavirus , the total number of confirmed cases and total Deaths. I am using a JSON API to get the data and displaying it using a RecyclerView . The app works fine , and i get a list of all the countries with their respective case counts. I want to add a search option so that the users can filter the list and find a specific country. How do i do that? I am new to programming , if someone could help with this that would be awesome.
Here is the code snippet
MainActivity.java
private RecyclerView mRecyclerView;
private Corona_Stats_Adapter mCorona_Stats_Adapter;
private TextView mErrorDisplay;
private ProgressBar mProgressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.corona_stats);
mRecyclerView = (RecyclerView)findViewById(R.id.Corona_stats_recycler);
mErrorDisplay = (TextView) findViewById(R.id.tv_error_message_display);
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
mRecyclerView.setLayoutManager(layoutManager);
mRecyclerView.setHasFixedSize(true);
mCorona_Stats_Adapter = new Corona_Stats_Adapter();
mRecyclerView.setAdapter(mCorona_Stats_Adapter);
mProgressBar = (ProgressBar)findViewById(R.id.pb_loading_indicator) ;
loadCoronaData();
}
private void loadCoronaData(){
showCoronaDataView();
//String Country = String.valueOf(mSearchQuery.getText());
new Fetch_data().execute();
}
private void showCoronaDataView(){
mErrorDisplay.setVisibility(View.INVISIBLE);
mRecyclerView.setVisibility(View.VISIBLE);
}
private void showErrorMessage(){
mRecyclerView.setVisibility(View.INVISIBLE);
mErrorDisplay.setVisibility(View.VISIBLE);
}
public class Fetch_data extends AsyncTask<Void,Void,String[]> {
#Override
protected void onPreExecute() {
super.onPreExecute();
mProgressBar.setVisibility(View.VISIBLE);
}
#Override
protected String[] doInBackground(Void... voids) {
URL covidRequestURL = NetworkUtils.buildUrl();
try {
String JSONCovidResponse = NetworkUtils.getResponseFromHttpUrl(covidRequestURL);
String[] simpleJsonCovidData = CovidJSON_Utils.getSimpleStringFromJson(MainActivity.this, JSONCovidResponse);
return simpleJsonCovidData;
} catch (IOException | JSONException e) {
e.printStackTrace();
return null;
}
}
#Override
protected void onPostExecute(String[] coronaData) {
mProgressBar.setVisibility(View.INVISIBLE);
if(coronaData !=null){
showCoronaDataView();
mCorona_Stats_Adapter.setCoronaData(coronaData);
} else{
showErrorMessage();
}
}
}
}
RecyclerView Adapter class Corona_stats_Adapter.java
public class Corona_Stats_Adapter extends RecyclerView.Adapter<Corona_Stats_Adapter.Corona_Stats_AdapterViewHolder>
{
private Context context;
// private List<Country> countryList;
// private List<Country> countryListFiltered;
private String[] mCoronaData;
public Corona_Stats_Adapter(){
}
#NonNull
#Override
public Corona_Stats_AdapterViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int viewType) {
Context context = viewGroup.getContext();
int LayoutIdForListItem =R.layout.corona_stats_list_item;
LayoutInflater inflater =LayoutInflater.from(context);
boolean ShouldAttachToParentImmediately = false;
View view = inflater.inflate(LayoutIdForListItem,viewGroup,ShouldAttachToParentImmediately);
return new Corona_Stats_AdapterViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull Corona_Stats_AdapterViewHolder corona_stats_adapterViewHolder, int position) {
String coronaStats = mCoronaData[position];
corona_stats_adapterViewHolder.mCoronaTextView.setText(coronaStats);
}
#Override
public int getItemCount() {
if(null == mCoronaData) return 0;
return mCoronaData.length;
// return countryListFiltered.size();
}
public class Corona_Stats_AdapterViewHolder extends RecyclerView.ViewHolder {
public final TextView mCoronaTextView;
public Corona_Stats_AdapterViewHolder(#NonNull View view) {
super(view);
mCoronaTextView = (TextView) view.findViewById(R.id.tv_corona_data);
}
}
public void setCoronaData(String[] coronaData){
mCoronaData = coronaData;
notifyDataSetChanged();
}
}
Parsing the JSON data in CovidJSON_Utils.java
public final class CovidJSON_Utils {
public static String[] getSimpleStringFromJson(Context context, String codivJsonString)
throws JSONException {
final String COV_COUNTRY = "Countries";
final String COV_CONFIRMED = "confirmed";
final String COV_DEATHS = "deaths";
final String COV_MESSAGE_CODE = "code";
String[] parsedCovidData = null;
JSONObject covidJsonObject = new JSONObject(codivJsonString);
if (covidJsonObject.has(COV_MESSAGE_CODE)) {
int errorCode = covidJsonObject.getInt(COV_MESSAGE_CODE);
switch (errorCode) {
case HttpURLConnection.HTTP_OK:
break;
case HttpURLConnection.HTTP_NOT_FOUND:
return null;
default:
return null;
}
}
JSONArray countryCovidArray = covidJsonObject.getJSONArray(COV_COUNTRY);
parsedCovidData = new String[countryCovidArray.length()];
for (int i = 0; i < countryCovidArray.length(); i++) {
JSONObject countryJSONObject = countryCovidArray.getJSONObject(i);
String Country = countryJSONObject.getString("Country");
String Confirmed = String.valueOf(countryJSONObject.getInt("TotalConfirmed"));
String Deaths = String.valueOf(countryJSONObject.getInt("TotalDeaths"));
parsedCovidData[i] = Country + "- Cases " + Confirmed + "- Deaths " + Deaths;
}
return parsedCovidData;
}
}

The problem is with below initialization in the MainActivity.Oncreate method
mCorona_Stats_Adapter = new Corona_Stats_Adapter(this,countries);
Initialize the adapter in onPostExecute method with updated countries data.
Hope this will help you.

You have to set arraylist to update country data in adapter after getting data from the server.
Public void setCoronaData (Arraylist coronaData) {
countryList = coronaData;
notifyDataSetChanged ();
}

Holder cardview change textview color error

i want to change color of my textview inside of cardview when its value is "kritis" or "kurang" but somehow everytime when my textview in position 0 and its value is either kritis or kurang it always change color textiew in position 0 and also position 7, and also when its in position 1 it will set color text view in position 8 too and so... and then i try to use logd to see howmany times my setcolor initiate and its only 1x (when changing color only position 1 and 7) or 2x (when changing color text position 0,1,7,8)(my cardview is inside recyclerview)
this is my adapter code
public class ListAdapter extends RecyclerView.Adapter<form_mhs_04_fragment2.ListAdapter.ViewHolder>
{
private ArrayList<DataNote> dataList;
public ListAdapter(ArrayList<DataNote> data)
{

this is how i send data to adapter
public void initListView(String UserId){
Call<ListForm4Response> getListForm4 = mApiService.getListForm4(
UserId
);
getListForm4.enqueue(new Callback<ListForm4Response>() {
#Override
public void onResponse(Call<ListForm4Response> call, Response<ListForm4Response> response) {
boolean iserror_ = response.body().getError();
if (iserror_ == false) {
List<List_Form4> list = new ArrayList<>();
list = response.body().getEvalMhsf4();
ipk_cap = new String[list.size()];
ipk_kat = new String[list.size()];
sks_cap = new String[list.size()];
sks_kat = new String[list.size()];
catatan = new String[list.size()];
semester = new String[list.size()];
for (int i =0;i<list.size();i++) {
ipk_cap[i] = list.get(i).getIpkMhs();
ipk_kat[i] = list.get(i).getKategoriIpk();
sks_cap[i] = String.valueOf(list.get(i).getSksMhs());
sks_kat[i] = list.get(i).getKategoriSks();
catatan[i] = list.get(i).getCatatan();
semester[i] = list.get(i).getSemester();
}
ArrayList data = new ArrayList<DataNote>();
for (int i = 0; i < list.size(); i++)
{
data.add(
new DataNote
(
ipk_cap[i],
ipk_kat[i],
sks_cap[i],
sks_kat[i],
catatan[i],
semester[i]
));
}
mListadapter = new form_mhs_04_fragment2.ListAdapter(data);
listview.setAdapter(mListadapter);
}
}
#Override
public void onFailure(Call<ListForm4Response> call, Throwable t) {
Toast.makeText(getActivity().getBaseContext(), "Koneksi Jaringan Bermasalah", Toast.LENGTH_SHORT).show();
Log.e("debug", "onFailure: ERROR > " + t.toString());
Intent intent = new Intent(getActivity().getBaseContext(), Form_Mhs_Menu.class);
getActivity().startActivity(intent);
}
});
}
and this is my Datanote
package com.example.bimbinganpasi.Form_04.adapter;
public class DataNote {
String ipkkat,ipkcap,skskat,skscap,catatan,semester;
public DataNote(String ipkcap, String ipkkat, String skscap, String skskat,String catatan ,String semester) {
this.ipkkat = ipkkat;
this.ipkcap = ipkcap;
this.skskat = skskat;
this.skscap = skscap;
this.catatan = catatan;
this.semester = semester;
}
public String getIpkkat() {
return ipkkat;
}
public String getIpkcap() {
return ipkcap;
}
public String getSkskat() {
return skskat;
}
public String getSkscap() {
return skscap;
}
public String getCatatan() {
return catatan;
}
public String getSemester() {
return semester;
}
}

try adding else to set default background color :
if(holder.textViewSKSkat.getText().equals("kritis") || holder.textViewSKSkat.getText().equals("kurang")){
holder.textViewSKSkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewSKSkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}
if(holder.textViewIPKkat.getText().equals("kritis") || holder.textViewIPKkat.getText().equals("kurang")){
holder.textViewIPKkat.setTextColor(Color.rgb(255,0,0));
Log.d("testing", "ayayaya");
} else {
holder.textViewIPKkat.setTextColor(Color.rgb(0,0,0)); //TODO : SET DEFAULT COLOR
}

In My Case i tried this code..
holder.textview.setColor(ContextCompat.getColor(YourActivity.this,R.color.colorPrimary));

how to put a few data into array variable and post as JSONarray?

I'm trying to make a laundry ordering application. I've made it to the order process, at the end of the order process, the user clicks the next button to checkout the ordered results, I have successfully made the checkout results, but what I made is still in one variable string. how to put the checkout results into an array variable so that I can post the results in the form of JSONArray?
HERE IS MY ORDER ACTIVITY CODE :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_produk);
// menghubungkan variablel pada layout dan pada java
listProduk = (ListView)findViewById(R.id.list_produk);
swipeProduct = (SwipeRefreshLayout)findViewById(R.id.swipeProduct);
radioExpress = (RadioButton)findViewById(R.id.radio_express);
radioReguler = (RadioButton)findViewById(R.id.radio_regular);
tvTotal = (TextView)findViewById(R.id.total);
next = (Button)findViewById(R.id.button_next);
actionBar = getSupportActionBar();
laundry_id = getIntent().getStringExtra(TAG_LAUNDRY_ID);
// untuk mengisi data dari JSON ke dalam adapter
productAdapter = new CheckboxAdapter(this, (ArrayList<ProductModel>) productList, this);
listProduk.setAdapter(productAdapter);
listProduk.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
productAdapter.setCheckBox(position);
}
});
// menampilkan widget refresh
swipeProduct.setOnRefreshListener(this);
swipeProduct.post(new Runnable() {
#Override
public void run() {
swipeProduct.setRefreshing(true);
productList.clear();
tvTotal.setText(String.valueOf(0));
radioReguler.isChecked();
regular = true;
productAdapter.notifyDataSetChanged();
callProduct();
}
}
);
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String checkbox = "";
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(dipilih);
}
});
}
private void formSubmit(String hasil){
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
LayoutInflater inflater = getLayoutInflater();
View dialogView = inflater.inflate(R.layout.form_submit, null);
dialog.setView(dialogView);
dialog.setIcon(R.mipmap.ic_launcher);
dialog.setTitle("Menu Yang Dipilih");
dialog.setCancelable(true);
txtnamaProduk = (TextView) dialogView.findViewById(R.id.txtNama_produk);
txtnamaProduk.setText(hasil);
dialog.setNeutralButton("CLOSE", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
dialog.show();
}
AND HERE IS THE CODE OF THE RESULT :
next.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String checkbox = "";
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(dipilih);
}
});
}
in my code above, I still use the variable checkbox to accommodate all the results of the order chosen by the user. how to put all the result into array variable so i can post to server as a JSONArray? Please help me to solve this problem. because i'm still a beginner in android.
HERE IS MY ADAPTER CODE IF NEEDED :
public class CheckboxAdapter extends BaseAdapter{

}
return view;
}
public ArrayList<ProductModel> getAllData(){
return productItems;
}
public void setCheckBox(int position){
ProductModel items = productItems.get(position);
items.setCheckbox(!items.isCheckbox());
notifyDataSetChanged();
}
static class ViewHolder{
TextView decrease, count, increase, price;

}
}

just create getter setter method of Arraylist like below
CompleteOrder:-
public class CompleteOrder {
List<OrderItem> order_items;
public List<OrderItem> getOrder_items() {
return order_items;
}
public void setOrder_items(List<OrderItem> order_items) {
this.order_items = order_items;
}
}
Create another Getter setter class of variable you want to add in arraylist
OrderItem:-
public class OrderItem {
String product_name;
int product_total;
public OrderItem(String product_name, int product_total) {
this.product_name = product_name;
this.product_total = product_total;
}
public String getProduct_name() {
return product_name;
}
public void setProduct_name(String product_name) {
this.product_name = product_name;
}
public int getProduct_total() {
return product_total;
}
public void setProduct_total(int product_total) {
this.product_total = product_total;
}
}
Now in your onClick method just create new List as below
public void onClick(View view) {
String checkbox = "";
CompleteOrder completeOrder=new CompleteOrder();
List<OrderItem> masterProductorderCount=new ArrayList<>();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
masterProductorderCount.add(new OrderItem(holder.getProduct_name(),total);
}
}
completeOrder.setOrder_items(masterProductorderCount);
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
formSubmit(completeOrder);//pass object of CompleteOrder
}
});
CompleteOrder object give JSON output as below
{
"CompleteOrder":[
{
"product_name":"your product name",
"product_total":1
},
{
"product_name":"your product name",
"product_total":1
},
{
"product_name":"your product name",
"product_total":1
}
]
}

make a model that contains product name , total and etc,
then put each data into an object and put each object into an array
finally use Gson to map properties to model / list of models or the other way around.
ArrayList<Model> list = new ArrayList<>();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
Model model = new Model();
model.productName = hold.getProduct_name();
model.total = total;
list.add(model);
}
}
String jsonArray = Gson().toJson(list);

You need to create a JSONObject for each entry in the JSONArray.
As far as I can see this should take care of it:
public void onClick(View view) {
String checkbox = "";
JSONArray jsonArray = new JSONArray();
for (ProductModel hold : productAdapter.getAllData()) {
int total = Integer.parseInt(hold.getProduct_price())*(hold.getCountProduct());
if (hold.isCheckbox()) {
checkbox += "\n" + hold.getProduct_name() + " " + total;
JSONObject jsonObj = new JSONObject();
jsonObj.put("product_name", hold.getProduct_name());
jsonObj.put("product_total", total);
jsonArray.put(jsonObj);
}
}
if (!checkbox.isEmpty()) {
dipilih = checkbox;
} else {
dipilih = "Anda Belum Memilih Menu.";
}
String jsonArrayString = jsonArray.toString();
formSubmit(dipilih);
}
Depending on your data the resulting string from jsonArrayString would be:
{[
{"product_name":"product1","product_total":1},
{"product_name":"product2","product_total":2},
{"product_name":"product3","product_total":3}
]}
I really do not know what you intend on doing with the JSON data so I just created a String "jsonArrayString".. do what ever you need to with it.

The issue I have is that I want to display the timer (the timeLeftText String) in the txtTempsRestant TextView, but I can't access it. Can anyone give me advice?
When I print in the console and the output is correct, but I'm not able to display it. Should I change the way I'm working?

You don't want to declare the TextView static if you'll be changing the value.
Try declaring it outside the method here:
public class TicketAdapter extends ArrayAdapter<TicketModel> implements View.OnClickListener{
private ArrayList<TicketModel> dataSet;
Context mContext;
static long timeLeftMS = Long.valueOf(TicketModel.getTempsRestantTicket());
private TextView txtTempsRestant ;
// View lookup cache
private static class ViewHolder {
TextView txtName;
TextView txtType;
TextView txtDate;
TextView txtSLA;
ImageView info;
RelativeLayout layout;
TextView txtTempsRestant ;
}

Hi i have a code its good
beucse u dont need definination 3 textview for right and left ,....
You will create one TextView and use this code for create
private void Time() {
mCountTimer = new CountDownTimer(aTime, 1000) {
#Override
public void onTick(long millisUntilFinished) {
aMinute = (int) (millisUntilFinished / 1000) / 60;
mSecond = (int) (millisUntilFinished / 1000) % 60;
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", aMinute, mSecond));
}
#Override
public void onFinish() {
mTimer.setText(String.format(Locale.getDefault(), "%d:%02d", 0, 0));
mSend_Again.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Your EVENT
}
});
}
}.start();
}
