My data of recyclerview loss in scroll down

I have a recyclerview and set text some textview in it. when I scroll down or my fragment goes to onPause state my data loss.
what can i do?
import static com.test.mohammaddvi.snappfood.Adapter.SectionListDataAdapter.decodeSampledBitmapFromResource;
public class RecyclerViewMenuFragmentAdapter extends RecyclerView.Adapter<RecyclerViewMenuFragmentAdapter.SingleItemInMenuFragment> {
private ArrayList<Food> foodList;

public RecyclerViewMenuFragmentAdapter(ArrayList<Food> foodList, Context mContext) {
this.foodList = foodList;
this.mContext = mContext;
}
#NonNull
#Override
public RecyclerViewMenuFragmentAdapter.SingleItemInMenuFragment onCreateViewHolder(ViewGroup parent, int viewType) {

return new RecyclerViewMenuFragmentAdapter.SingleItemInMenuFragment(v);
}
#Override
public void onBindViewHolder(final RecyclerViewMenuFragmentAdapter.SingleItemInMenuFragment holder, int position) {
Food food = foodList.get(position);
holder.foodName.setText(food.getName());
holder.foodDetails.setText(food.getDetails());
holder.foodPrice.setText(food.getPrice() + " تومان ");
holder.foodOrderNumber.setVisibility(View.INVISIBLE);
holder.foodMinusButton.setVisibility(View.INVISIBLE);
holder.foodOrderNumber.setText(0 + "");
holder.foodImage.setImageBitmap(decodeSampledBitmapFromResource(mContext.getResources(), mContext.getResources().getIdentifier(food.getImage(),
"drawable", mContext.getPackageName()), 50, 50));
handleClick(holder, position);
}
private void handleClick(final SingleItemInMenuFragment holder, final int position) {
holder.foodPlusButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int orderNumber = Integer.parseInt(holder.foodOrderNumber.getText().toString());
holder.foodOrderNumber.setText(orderNumber + 1 + "");
holder.foodOrderNumber.setVisibility(View.VISIBLE);
holder.foodMinusButton.setVisibility(View.VISIBLE);
}
});
holder.foodMinusButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int orderNumber = Integer.parseInt(holder.foodOrderNumber.getText().toString());
if (orderNumber > 1) {
holder.foodOrderNumber.setText(orderNumber - 1 + "");
holder.foodOrderNumber.setVisibility(View.VISIBLE);
}
if (orderNumber == 1) {
holder.foodOrderNumber.setText(orderNumber - 1 + "");
holder.foodOrderNumber.setVisibility(View.INVISIBLE);
holder.foodMinusButton.setVisibility(View.INVISIBLE);
}
}
});
}
#Override
public int getItemCount() {
return (null != foodList ? foodList.size() : 0);
}
public class SingleItemInMenuFragment extends RecyclerView.ViewHolder {
TextView foodName;
TextView foodPrice;
Button foodPlusButton;
Button foodMinusButton;
TextView foodOrderNumber;
ImageView foodImage;
TextView foodDetails;
SingleItemInMenuFragment(View itemView) {
super(itemView);
this.foodName = itemView.findViewById(R.id.foodName);
this.foodImage = itemView.findViewById(R.id.imageFood);
this.foodPrice = itemView.findViewById(R.id.foodPrice);
this.foodDetails = itemView.findViewById(R.id.foodDetails);
this.foodPlusButton = itemView.findViewById(R.id.plusbutton);
this.foodMinusButton = itemView.findViewById(R.id.minusbutton);
this.foodOrderNumber = itemView.findViewById(R.id.ordernumber);
}
}
}
and this is my fragment that i use recyclerview in that:
public class MenuFragment extends Fragment{
private static final String TAG = "menufragment";
ArrayList<Food> allfoods = new ArrayList<>();
RecyclerView recyclerview;
private static Bundle bundle;
private final String KEY_RECYCLER_STATE= "recycler_state";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.menufragment, container, false);
}
#Override
public void onStart() {
super.onStart();
String jsonFilePath = "foods.json";
recyclerview = getActivity().findViewById(R.id.lstitems);
RecyclerViewMenuFragmentAdapter adapter = new RecyclerViewMenuFragmentAdapter(allfoods, getContext());
recyclerview.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false));
recyclerview.setHasFixedSize(true);
recyclerview.setAdapter(adapter);
parsJson(jsonFilePath);
}
//this method is for read a local json and return a string
public String readLocalJson(String jsonFile) {
String json;
try {
InputStream is = getActivity().getAssets().open(jsonFile);
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException e) {
e.printStackTrace();
return null;
}
return json;
}
public void parsJson(String jsonFilePath) {
try {
JSONObject obj = new JSONObject(readLocalJson(jsonFilePath));
JSONArray jsonArray = obj.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
String image = jsonObject.getString("image");
JSONArray jsonArrayFoot = jsonObject.getJSONArray("foots");
for (int j = 0; j < jsonArrayFoot.length(); j++) {
JSONObject jsonObjectFoot = jsonArrayFoot.getJSONObject(j);
String foodName = jsonObjectFoot.getString("name");
String fooddetails = jsonObjectFoot.getString("fooddetails");
String price = jsonObjectFoot.getString("price");
allfoods.add(new Food(foodName, price, fooddetails, image));
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}

Basically, you just initialized the data on onStart which will eventually called when your activity/fragment is resumed, and because of that all data you've changed was overwritten to initial data.
Move your onStart initialization to onViewCreated:
#Override
public void onViewCreated() {
super.onViewCreated();
String jsonFilePath = "foods.json";
recyclerview = getActivity().findViewById(R.id.lstitems);
RecyclerViewMenuFragmentAdapter adapter = new RecyclerViewMenuFragmentAdapter(allfoods, getContext());
recyclerview.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false));
recyclerview.setHasFixedSize(true);
recyclerview.setAdapter(adapter);
parsJson(jsonFilePath);
}
And for scrolling, its normal because RecyclerView recycles the view from the list above but the data is not, so what you need to do is store values from the list source.
#Override
public void onBindViewHolder(final RecyclerViewMenuFragmentAdapter.SingleItemInMenuFragment holder, int position) {
Food food = foodList.get(position);
holder.foodName.setText(food.getName());
holder.foodDetails.setText(food.getDetails());
holder.foodPrice.setText(food.getPrice() + " تومان ");
holder.foodOrderNumber.setVisibility(View.INVISIBLE);
holder.foodMinusButton.setVisibility(View.INVISIBLE);
holder.foodOrderNumber.setText(food.getFoodOrderNumber());
holder.foodImage.setImageBitmap(decodeSampledBitmapFromResource(mContext.getResources(), mContext.getResources().getIdentifier(food.getImage(),
"drawable", mContext.getPackageName()), 50, 50));
handleClick(holder, position);
}
private void handleClick(final SingleItemInMenuFragment holder, final int position) {
holder.foodPlusButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int orderNumber = Integer.parseInt(holder.foodOrderNumber.getText().toString());
int newOrderNumber = orderNumber + 1;
Food food = foodList.get(position);
food.setFoodOrderNumber(newOrderNumber);
holder.foodOrderNumber.setText(newOrderNumber + "");
holder.foodOrderNumber.setVisibility(View.VISIBLE);
holder.foodMinusButton.setVisibility(View.VISIBLE);
}
});
holder.foodMinusButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Food food = foodList.get(position);
int orderNumber = food.getFoodOrderNumber();
if (orderNumber > 1) {
int newOrderNumber = orderNumber - 1;
food.setFoodOrderNumber(newOrderNumber);
holder.foodOrderNumber.setText(newOrderNumber + "");
holder.foodOrderNumber.setVisibility(View.VISIBLE);
}
if (orderNumber == 1) {
int newOrderNumber = orderNumber - 1;
food.setFoodOrderNumber(newOrderNumber);
holder.foodOrderNumber.setText(newOrderNumber + "");
holder.foodOrderNumber.setVisibility(View.INVISIBLE);
holder.foodMinusButton.setVisibility(View.INVISIBLE);
}
}
});
}
And on your Food object just add this field and functions:
public class Food {
int foodOrderNumber;
public int getFoodOrderNumber() {
return foodOrderNumber;
}
public void setFoodOrderNumber(int foodOrderNumber) {
this.foodOrderNumber = foodOrderNumber;
}
}

add this line to your onBindViewHolder method and check again if the problem still exits:
holder.setIsRecyclable(false);

How to add Native Ads in between my data items?

I want to know where to add a check to hide and unhide the items. Lets say I got 6 items. So, in the recyclerview it should show 9 items including the native ads. (every 3rd position).

if (position == 0 || (position + 1) % 3 == 0) { //add your nativeAdd here }

changing items in recyclerview adapter

I inserted/removing from particular position in ArrayList onBindViewHolder . Now , i want to show this modified list on recyclerview .

you will see following lines in above code where i am removing/inserting item in a list onBindview and would like to show same in recyclerview .
But right now i am getting normal datalist(unchanged) .
//Here i removed and inserted item in list .
dataList.remove(i);
dataList.add(0,ci);
Please help me to achieve this .

onBindViewHolder is not the place where you should update your adapter. The staregy is to update item inside your Adapter data list and then notifyDataChanged(). For example thise are the methods for updating info inside my adapter:
public void update(Track track) {
tracks.remove(track);
add(track);
}
public void add (Track track) {
tracks.add(track);
this.notifyDataSetChanged();
}
public void addTracks(List<Track> tracks){
this.tracks.addAll(tracks);
this.notifyDataSetChanged();
}
public void clearAndAddTracks(List<Track> tracks) {
for (int i = 0; i < this.tracks.size(); i++) {
if (!this.tracks.get(i).isRunning()){
}
}
this.tracks.clear();
this.tracks.addAll(tracks);
this.notifyDataSetChanged();
}

I fetch CategoryID from Adapter Class and pass this with putExtra.
for load more data i use Interface class : OnLoadMoreListener
How can i fix this bug and when scrolling on posts, show next 10 posts!
Attention : Please don't give me negative points, help me and i really need you helps! thanks all <3 How can i fix it?

I find my problem! but my problem is strange!!! i remove this code :
mAdapter.setOnLoadMoreListener(new OnLoadMoreListener() {
#Override
public void onLoadMore() {
dataModels.add(null);
mAdapter.notifyItemInserted(dataModels.size() - 1);
LoadMoreData(catID, pageCount);
}
});
and write again this, fix my problem!!!! it's very strange :D .
Hope help you
