how to handle click event for each item in recyclerview child in nested recyclerview

I have a nested recyclerview to show the list of foods in each category. When the user clicks the increase or decrease button, the quantity will be updated to the quantity textview and synced to the cart stored in the database, but currently I don't know how to listen for the event when the user clicks these buttons.
Here is my current UI when run:
enter image description here
Here is my fragment:
public class TabOrderFragment extends Fragment {
private static final String ARG_RESTAURANT_ID = "restaurantId";
private int restaurantId;
View view;
RecyclerView menuRecyclerView;
RecyclerView.LayoutManager layoutManager;
ArrayList<Menu> menuArrayList;
MenuAdapter menuAdapter;
public TabOrderFragment() { }
public static TabOrderFragment newInstance(int restaurantId) {
TabOrderFragment fragment = new TabOrderFragment();
Bundle args = new Bundle();
args.putInt(ARG_RESTAURANT_ID, restaurantId);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
restaurantId = getArguments().getInt(ARG_RESTAURANT_ID);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.fragment_tab_order, container, false);
if(restaurantId != 0) {
DatabaseHandler databaseHandler = DatabaseHandler.getInstance(getActivity());
menuArrayList = new ArrayList<Menu>();
menuArrayList = databaseHandler.getAllMenuFoodsByIdRestaurant(restaurantId);
menuRecyclerView = view.findViewById(R.id.rcv_foods_menu);
menuAdapter = new MenuAdapter(getActivity().getApplicationContext(), restaurantId);
layoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
menuRecyclerView.setLayoutManager(layoutManager);
menuAdapter.setData(menuArrayList);
menuRecyclerView.setAdapter(menuAdapter);
}
return view;
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.d("TabOrderFragment", "Restaurant Id = " + restaurantId);
}
Here is my MenuAdapter:
public class MenuAdapter extends RecyclerView.Adapter<MenuAdapter.MenuViewHolder> {
Context context;
private int restaurantId;
private RecyclerView.RecycledViewPool viewPool = new RecyclerView.RecycledViewPool();
ArrayList<Menu> menuList;
public MenuAdapter(ArrayList<Menu> menuList) {
this.menuList = menuList;
}
public MenuAdapter(Context context, int restaurantId) {
this.context = context;
this.restaurantId = restaurantId;
}
public void setData(ArrayList<Menu> menuList) {
this.menuList = menuList;
notifyDataSetChanged();
}
#NonNull
#Override
public MenuViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_foods_menu, parent, false);
return new MenuViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull MenuViewHolder holder, int position) {
Menu menu = menuList.get(position);
holder.txtMenuTitle.setText(menu.getTitle().concat(" (" + String.valueOf(menu.getQuantity()) + ")"));
LinearLayoutManager layoutManager = new LinearLayoutManager(holder.rcvListFoods.getContext(), LinearLayoutManager.VERTICAL, false);
layoutManager.setInitialPrefetchItemCount(menu.getFoods().size());
FoodAdapter foodAdapter = new FoodAdapter(menu.getFoods(), restaurantId);
holder.rcvListFoods.setLayoutManager(layoutManager);
holder.rcvListFoods.setAdapter(foodAdapter);
holder.rcvListFoods.setRecycledViewPool(viewPool);
}
#Override
public int getItemCount() {
if(menuList != null) {
return menuList.size();
}
return 0;
}
public class MenuViewHolder extends RecyclerView.ViewHolder {
private TextView txtMenuTitle;
private RecyclerView rcvListFoods;
public MenuViewHolder(#NonNull View itemView) {
super(itemView);
txtMenuTitle = itemView.findViewById(R.id.txv_menu_title);
rcvListFoods = itemView.findViewById(R.id.rcv_list_foods);
}
}
}
Here is my FoodAdapter:
public class FoodAdapter extends RecyclerView.Adapter<FoodAdapter.FoodViewHolder> {
private ArrayList<Food> foodList;
private int restaurantId;
private int userId;
SharedPreferences sharedPreferences;
public FoodAdapter(ArrayList<Food> foodList, int restaurantId) {
this.foodList = foodList;
this.restaurantId = restaurantId;
}
#NonNull
#Override
public FoodViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
sharedPreferences = fragmentActivity.getSharedPreferences("currentUser", Context.MODE_PRIVATE);
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_food, parent, false);
return new FoodViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull FoodViewHolder holder, int position) {
Food food =foodList.get(position);
Picasso.get().load(food.getThumbImage()).into(holder.foodThumbImage);
holder.foodName.setText(food.getName());
holder.foodDescription.setText(food.getDescription());
double price = Double.parseDouble(food.getPrice());
DecimalFormat formatter = new DecimalFormat("#,###");
holder.foodPrice.setText(formatter.format(price) + "đ");
}
#Override
public int getItemCount() {
if(foodList != null) {
return foodList.size();
}
return 0;
}
public class FoodViewHolder extends RecyclerView.ViewHolder {
private ImageView foodThumbImage;
private TextView foodName;
private TextView foodDescription;
private TextView foodPrice;
private TextView quantity;
private MaterialButton increaseBtn;
private MaterialButton decreaseBtn;
private ItemClickListener itemClickListener;
public FoodViewHolder(#NonNull View itemView) {
super(itemView);
foodThumbImage = itemView.findViewById(R.id.image_food);
foodName = itemView.findViewById(R.id.txv_food_name);
foodDescription = itemView.findViewById(R.id.txv_food_description);
foodPrice = itemView.findViewById(R.id.txv_food_price);
quantity = itemView.findViewById(R.id.txv_quantity);
increaseBtn = itemView.findViewById(R.id.btn_increase);
decreaseBtn = itemView.findViewById(R.id.btn_decrease);
}
}

in your food adapter's onBindViewHolder method use
holder.increaseBtn.setOnClickListener{
onIncreaseClick()
}
while create an interface like
interface Listener{
public void onIncreaseClick();
public void onDecreaseClick();
}
and implement your interface in your activity or fragment or viewmodel where you can listen for the click event

What you can do generally when you have something like that, is to create an interface for the interaction with the Recycler view:
interface Interaction {
public void onFoodClick(Food food)
}
Then you add an instance of this interface in your recycler view adapter, and you let your activity or fragment implement this interface, please find a good explanation here: https://stackoverflow.com/a/31671289/7334951

Recyclerview items don't answer for first click

I'm having a problem with assigning onclicklistener to recyclerview items.
When I click the item, first click is ignored and listener doesn't run.
I mean, I have to click once, and then again to run the listener.
Once it runs, listener works well.
here is my code.

Calling setAdapter on Fragment (Recycler View) not working

I tried to set the adapter on fragment, but nothing shows up.
The object retrieves the data from API but doesn't show on the screen.
I have already put the break point on rvItem.setAdapter(mainAdapter); but nothings happen, the debug passes straight through.
public class ItemFragment extends Fragment {
private MainAdapter mainAdapter;
private ItemPresenter itemPresenter;
private GridLayoutManager mLayoutManager;
private List<ObjectAdapter> list = new ArrayList<>();

#Bind(R.id.rvItem)
RecyclerView rvItem;
public ItemFragment() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_item, container, false);
ButterKnife.bind(this, view);
itemPresenter = new ItemPresenter();
mLayoutManager = new GridLayoutManager(getActivity(), 4);
rvItem.setLayoutManager(mLayoutManager);
getList();
return view;
}
private void getList() {
itemPresenter.loadItemList(region, "all", AppConfigs.api_key, new ItemListListener() {
#Override

}
});
}
public void displayItemList(List<ObjectAdapter> itemList) {
list = itemList;
mainAdapter = new MainAdapter(getActivity(), list, new MainAdapter.OnObjectClickListener() {
#Override
public void OnObjectClickListener(ObjectAdapter objectAdapter) {
Toast.makeText(getActivity(), "Object Adapter" + objectAdapter.Id, Toast.LENGTH_SHORT).show();
}
});
rvItem.setAdapter(mainAdapter);
mainAdapter.notifyDataSetChanged();
}
}
Adapter:

}
#Override

switch (ob.Type){
case CHAMPION: url = String.format(AppConfigs.portraitChampion, ob.Portrait);
break;
case SPELL: url = String.format(AppConfigs.portraitSpell, ob.Portrait);

break;
}
Picasso.with(mContext).load(url).into(holder.ivRetrato);
}
#Override

return this.mObjecterList.size();
}
public static class MainAdapterViewHolder extends RecyclerView.ViewHolder {
public TextView tvNameText;
public ImageView ivRetrato;
public MainAdapterViewHolder(View itemView) {
super(itemView);
this.tvNameText = (TextView) itemView.findViewById(R.id.tvNameText);
this.ivRetrato = (ImageView) itemView.findViewById(R.id.ivImagePortrait);
}
public void bind(final ObjectAdapter objectAdapterListItem, final OnObjectClickListener listener) {
itemView.setOnClickListener(new View.OnClickListener() {
#Override

You need to set adapter directly at onCreateView method and call notifyDataSetChanged() of adapter when data loaded

Handle button click inside row in recyclerView

I would like to know how to handle position of the row if the adapter is changed - for example if I write something to SearchView - adapter has changed and position is different. I have done this (below), but it shows the item before changed position.
My issue is with Recycler view item click.
Could you help me with that?

private static OnItemClickListener listener;
public interface OnItemClickListener {
void onItemClick(View itemView, int position);
}
public void setOnItemClickListener(OnItemClickListener listener) {
this.listener = listener;
}

public ContactsRecyclerAdapter(Context context, List<Contact> contact) {
this.mContext = context;
this.mContacts = contact;
this.mContactsFiltered = contact;

listener.onItemClick(itemView, getLayoutPosition());
}
});

BindingHolder holder = new BindingHolder(view);
return holder;
}
#Override
public void onBindViewHolder(BindingHolder holder, int position) {
final Contact contact = mContactsFiltered.get(position);
holder.getBinding().setVariable(BR.contact, contact);
holder.getBinding().executePendingBindings();

}

//item click
mAdapter.setOnItemClickListener(new ContactsRecyclerAdapter.OnItemClickListener() {
#Override
public void onItemClick(View itemView, int position) {
Contact contact = SugarRecord.findById(Contact.class, (long) position + 1);
name = contact.getName();
number = contact.getNumber();
email = contact.getEmail();
showAlertDialog();
}
});
searchFilter();
return view;
}
public void sortList() {
if(mContact.size() > 0) {
if (!isSort) {
Collections.sort(mContact, new Comparator<Contact>() {
#Override
public int compare(Contact contact1, Contact contact2) {
return contact1.getName().compareToIgnoreCase(contact2.getName());
}
});
}
else {
Collections.reverse(mContact);
isSort = false;
}
}
mAdapter.notifyDataSetChanged();

Click listener does not work with a RecyclerView. use OnItemTouchListener()
RecyclerView recyclerView = findViewById(R.id.recycler);
recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
#Override public void onItemClick(View view, int position) {
// do whatever
}
#Override public void onLongItemClick(View view, int position) {
// do whatever
}
})
);

you have to overide onclick in BindingHolder class. Inside onclick method invoke a callback method of object passed via constructor etc
public static class BindingHolder extends RecyclerView.ViewHolder {
private ViewDataBinding binding;
public BindingHolder(final View rowView) {
super(rowView);
binding = DataBindingUtil.bind(rowView);
public void onClick(View view) {
//call a callback method here
}
}
public ViewDataBinding getBinding() {
return binding;
}
}

Recycler View + Stars instead of Checkboxes: keeping state while scrolling

I'm having the usual problem with a list + a RecyclerView: when I change the resource file of an item (aka: selected/unselected star icon) and then scroll, other items of the list are keeping the same selected/unselected state for their own star. Plus, when I select an item and then go back, I'm missing the selected/unselected state.
The fullStar and the emptyStar are simple Android Vector images.
Here it is my ListFragment:
public class PetrolStationListFragment extends Fragment {
private RecyclerView mPetrolStationRecyclerView;
private PetrolStationAdapter mAdapter;
private int itemPosition;
public static boolean toBeCreated;
private static final String ARG_POSITION = "position";
// Design pattern to instantiate a new fragment.
public static PetrolStationListFragment newInstance(int position) {
PetrolStationListFragment fragment = new PetrolStationListFragment();
Bundle args = new Bundle();
args.putInt(ARG_POSITION, position);
fragment.setArguments(args);
return fragment;
}

} else {
mFavourite = true;
}

}

this.mFavourite = favourite;
}
Any hint about how to fix this issue? I'm finding difficult to apply the CheckBoxes examples I've found to my own case.
