Ошибка адаптера RecyclerView после удаления элемента из ArrayList

1 голос
/ 20 января 2020

У меня есть 2 RecyclerView Адаптер с именами AddDrinkAdapter и DrinkDetailAdapter.

AddDrinkAdapter - для перечисления различных типов напитков и желаемого количества.

В то время как DrinkDetailAdapter - для перечисления этих напитков с подробной информацией.

Это мой AddDrinkAdapter Класс 

public class AddDrinkAdapter extends RecyclerView.Adapter<AddDrinkViewHolder> {
private ArrayList<DrinkQuantity> listDrinkQuantity = new ArrayList<>();
private AddDrinkFragment.callbackListener listener;
private final int min = 0;
private final int max = 5;

AddDrinkAdapter(ArrayList<DrinkQuantity> listDrinkQuantity, AddDrinkFragment.callbackListener callbackListener) {
    this.listDrinkQuantity = listDrinkQuantity;
    listener = callbackListener;
}

public ArrayList<DrinkQuantity> getListDrinkQuantity() {
    return listDrinkQuantity;
}

@NonNull
@Override
public AddDrinkViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_drink_quantity, parent, false);

    return new AddDrinkViewHolder(itemView);
}

@SuppressLint("SetTextI18n")
@Override
public void onBindViewHolder(@NonNull AddDrinkViewHolder holder, int position) {
    DrinkQuantity drinkQuantity = listDrinkQuantity.get(position);
    holder.mTvName.setText(drinkQuantity.getDrinkType());
    holder.mEtQuantity.setText(Integer.toString(drinkQuantity.getQuantity()));

    holder.mEtQuantity.addTextChangedListener(setTextWatcher(position, holder.mEtQuantity));
    holder.mIvMinus.setOnClickListener(onClick(holder, position, "minus"));
    holder.mIvAdd.setOnClickListener(onClick(holder, position, "add"));
}

@Override
public int getItemCount() {
    return listDrinkQuantity.size();
}

private TextWatcher setTextWatcher(int position, EditText et){
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            String value = charSequence.toString();
            if(!Util.isNullOrEmpty(value.trim())) {
                int num = Integer.parseInt(charSequence.toString());
                if(num < 0 || num > 5) {
                    listener.onChangeText(min, max, num);
                    et.setText("0");
                } else {
                    listDrinkQuantity.get(position).quantity = num;
                }
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}

private View.OnClickListener onClick(@NonNull AddDrinkViewHolder holder, int position, String mode) {
    return new View.OnClickListener() {
        @SuppressLint("SetTextI18n")
        @Override
        public void onClick(View view) {
            int qty = listDrinkQuantity.get(position).quantity;
            if (mode.equals("minus")) {
                if(qty == 0) {
                    listener.onChangeText(min,max,-1);
                    return; // min 0 : abort
                }
                qty--;
                holder.mEtQuantity.setText(Integer.toString(qty));
            } else if (mode.equals("add")) {
                if(qty == 5) {
                    listener.onChangeText(min,max,6);
                    return; // max 5 : abort
                }
                qty++;
                holder.mEtQuantity.setText(Integer.toString(qty));
            }
        }
    };
}
}

DrinkDetailAdapter Класс 

public class DrinkDetailAdapter extends RecyclerView.Adapter<DrinkDataViewHolder> {
private static final String TAG = DrinkDetailAdapter.class.getSimpleName();
private ArrayList<Drink> drinkList = new ArrayList<>();
private final String NAME = "name";
private final String SUGAR = "sugar";
private final String ICE = "ice";

DrinkDetailAdapter(ArrayList<Drink> drink_list) {
    drinkList = drink_list;
}

ArrayList<Drink> getDrinkDetailsArrayList() {
    return drinkList;
}

void reset() {
    for(int i=0; i < drinkList.size(); i++) {
        drinkList.get(i).getDrinkDetails().drink_name = "";
        drinkList.get(i).getDrinkDetails().sugar = "0";
        drinkList.get(i).getDrinkDetails().ice = "0";
    }
}

@NonNull
@Override
public DrinkDataViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_drink_check, parent, false);

    return new DrinkDataViewHolder(itemView);
}

@Override
public void onBindViewHolder(@NonNull DrinkDataViewHolder holder, int position) {
    Drink drink = drinkList.get(position);
    holder.mEtName.setText(drink.getDrinkDetails().drink_name);
    holder.mEtSugar.setText(drink.getDrinkDetails().sugar);
    holder.mEtIce.setText(drink.getDrinkDetails().ice);

    holder.mEtName.addTextChangedListener(updateData(position, NAME, holder));
    holder.mEtSugar.addTextChangedListener(updateData(position, SUGAR, holder));
    holder.mEtIce.addTextChangedListener(updateData(position, ICE, holder));
}

@Override
public int getItemCount() {
    return drinkList.size();
}

TextWatcher updateData(int position, String editText, @NonNull DrinkDataViewHolder holder) {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            switch (editText) {
                case NAME:
                    drinkList.get(position).getDrinkDetails().drink_name = charSequence.toString();
                    break;
                case SUGAR:
                    drinkList.get(position).getDrinkDetails().sugar = charSequence.toString();
                    break;
                case ICE:
                    drinkList.get(position).getDrinkDetails().ice = charSequence.toString();
                    break;
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}
}

После получения Drink количества, это код для обновления DrinkDetailAdapter ArrayList

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_ADD_DRINK) {
        if (resultCode == Activity.RESULT_OK) {
            try {
                Bundle args = data.getBundleExtra("args");
                if (args != null) {
                    drinkCheckResponse = args.getParcelable(DRINK_CHECK_RESPONSE);
                    drinkQuantityList.clear();
                    drinkQuantityList.addAll(drinkCheckResponse.getData().drink_quantities);
                }
            } catch (Exception e) {
                Logger.e(TAG, "onActivityResult Exception: msg[%s]", e.getMessage());
                Logger.logException(e);
            }
            updateDrinkList();
        }
    }
}

private void updateDrinkList() {
    for(int i = 0; i < drinkQuantityList.size(); i++) {
        setDrinkList(drinkQuantityList.get(i).drink_type, drinkQuantityList.get(i).quantity);
    }
    drinkDetailsAdapter.notifyDataSetChanged();
}

private void setDrinkList(String name, int enteredQuantity) {
    int drinkTypeCount = drinkTypeCount(name);
    int diffCount = enteredQuantity-drinkTypeCount;
    if (diffCount != 0) {
        addRemoveDrink(diffCount, enteredQuantity, name);
    }
}

private int drinkTypeCount(String name) {
    int count = 0;
    for(int i=0; i < drinkList.size(); i++) {
        String subName = drinkList.get(i).getDrinkDetails().drink_name.substring(0, drinkList.get(i).getDrinkDetails().drink_name.indexOf("(")).trim();
        if(subName.equals(name)) {
            count++;
        }
    }
    return count;
}

private void addRemoveDrink(int diffCount, int enteredQuantity, String name) {
    if(diffCount > 0) {
        for(int i=enteredQuantity-diffCount+1; i <= enteredQuantity; i++) {
            DrinkDetails drinkDetails = new DrinkDetails(name + " (" + i + ")");
            drinkList.add(new Drink(drinkDetails));
        }
    } else if(diffCount < 0) {
        for(int i=enteredQuantity-diffCount; i > enteredQuantity; i--) {
            for (Iterator<Drink> iterator = drinkList.iterator(); iterator.hasNext();) {
                Drink drink = iterator.next();
                if (drink.getDrinkDetails().drink_name.equals(name + " (" + i + ")")) {
                    // Remove the current element from the iterator and the list.
                    iterator.remove();
                    drinkDetailsAdapter.notifyItemRemoved(drinkList.indexOf(drink));
                }
            }
        }
    }
    Collections.sort(drinkList);
    Log.d(TAG, "addRemoveDrink: " + drinkList.size());
}

Это ошибка, которую я получил, когда добавляю количество 10-15 (общее для всех типов напитков), а затем минус количество к 0 или 1 для каждого типа.

В основном это 2 страницы для этих двух RecyclerView адаптеров.

    drink_type = in.readString();
    quantity = in.readInt();
}

public static final Creator<DrinkQuantity> CREATOR = new Creator<DrinkQuantity>() {
    @Override
    public DrinkQuantity createFromParcel(Parcel in) {
        return new DrinkQuantity(in);
    }

    @Override
    public DrinkQuantity[] newArray(int size) {
        return new DrinkQuantity[size];
    }
};

public String getDrinkType() {
    return drink_type;
}

public int getQuantity() {
    return quantity;
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel parcel, int i) {
    parcel.writeString(drink_type);
    parcel.writeInt(quantity);
}
}

Я нахожу структуру очень запутанной, поскольку AddDrinkAdapter использует ArrayList<DrinkQuantity> и DrinkDetailAdapter использует ArrayList<Drink>, тогда мне нужно выполнить l oop, чтобы сопоставить эти 2 списка. Если кто-то может изменить структуру, чтобы сделать это лучше, пожалуйста, сообщите мне. Спасибо.

После долгих часов отладки по этому вопросу, наконец, я увидел, в чем проблема. Моя функция updateData была той, которая вызывала у меня проблему, поскольку она содержит исходный int position.

Итак, это мой обновленный код для решения этой проблемы.

DrinkDetailAdapter Класс 

TextWatcher updateData(String editText, @NonNull DrinkDataViewHolder holder) {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            Drink drink = getDrink(holder.mTvDrinkName.getText().toString());
            if(drink == null) return;
            switch (editText) {
                switch (editText) {
                    case NAME:
                        drinkList.get(drinkList.indexOf(drink)).getDrinkDetails().drink_name = charSequence.toString();
                        break;
                    case SUGAR:
                        drinkList.get(drinkList.indexOf(drink)).getDrinkDetails().sugar = charSequence.toString();
                        break;
                    case ICE:
                        drinkList.get(drinkList.indexOf(drink)).getDrinkDetails().ice = charSequence.toString();
                        break;
                }
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    };
}

private Drink getDrink(String name) {
    for (Drink drink : drinkList) {
        if (drink.getDrinkDetails().drink_name.equalsIgnoreCase(name))
            return drink;
    }
    return null;
}
...
