пользовательский просмотр карт в Android в режиме recyclerView с использованием фрагментов

/ 01 мая 2018

Проблема в том, что мое приложение вылетает каждый раз, когда я его запускаю .. есть ли здесь проблемы? Я пытаюсь реализовать просмотры карт в программе recyclerView, которая инициализируется во фрагменте.

Вот мой код.

Это макет фрагмента

home.xml 

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container2"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<android.support.design.widget.FloatingActionButton
    android:id="@+id/floatingActionButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clickable="true"
    app:backgroundTint="@color/colorPrimary"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    android:layout_marginRight="8dp"
    android:layout_marginBottom="8dp"
    app:layout_constraintVertical_bias="1.0"
    app:srcCompat="@drawable/ic_home_black_24dp" />

 <android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true" />
</android.support.constraint.ConstraintLayout>

Вот макет карты с кучей текстов

item_list.xml

            </LinearLayout>
        </LinearLayout>
    </android.support.v7.widget.CardView>
</LinearLayout>

пока здесь, это класс, где у меня есть сеттеры и геттеры.

Items.java 

public class Items {
    private String currency;
    private String title;
    private int number;
    private int date;
    private int budget;
        public Items(){
        }
    public Items(String currency, String title,int number, int date, int   

    budget){
    this.currency = currency;
    this.title = title;
    this.number = number;
    this.date = date;
    this.budget = budget;
}
public String getTitle(){
    return title;
}
public void setTitle(String title){
    this.title = title;
}
public String getCurrency(){
    return currency;
}
public void setCurrency(String currency){
    this.currency = currency;
}
public int getNumber(){
    return number;
}
public void setNumber(int number){
    this.number = number;
}
public int getDate(){
    return date;
}
public void setDate(int date){
    this.date = date;
}
public int getBudget(){
    return budget;
}
public void setBudget(int budget){
    this.budget = budget;
    }


}

Ниже представлен адаптер указанного класса, как вы можете видеть!

ItemsAdapter.java 

import android.content.ClipData;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.List;

public class ItemsAdapter extends     
RecyclerView.Adapter<ItemsAdapter.myViewHolder>{
private Context mContext;
private List<Items> itemsList;

public class myViewHolder extends RecyclerView.ViewHolder {
    TextView title, currency, date, budget, number;

    public myViewHolder(View itemView) {
        super(itemView);
        title = (TextView) itemView.findViewById(R.id.tv_title);
        currency = (TextView) itemView.findViewById(R.id.tv_currency);
        date = (TextView) itemView.findViewById(R.id.tv_date);
        budget = (TextView) itemView.findViewById(R.id.tv_budget);
        number = (TextView) itemView.findViewById(R.id.tv_number);
    }
}

public ItemsAdapter(Context mContext, List<Items>itemsList){
    this.mContext = mContext;
    this.itemsList = itemsList;
}

@Override
public myViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view  = 

LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent,
false);

    return new myViewHolder(view);
}

@Override
public void onBindViewHolder(final myViewHolder holder, int position) {
    Items items = itemsList.get(position);
    holder.title.setText(items.getTitle());
    holder.currency.setText(items.getCurrency());
    holder.number.setText(items.getNumber());
    holder.budget.setText(items.getBudget());
    holder.date.setText(items.getDate());

}

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

В то время как здесь ниже класс фрагмента, где я хочу, чтобы при просмотре этого класса отображались карты.

Home.java 

public class Home extends Fragment {
    private RecyclerView rv;
    private ItemsAdapter adapter;
    private List<Items> itemsList;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.home, container, false);
    rv = (RecyclerView) rootView.findViewById(R.id.recyclerView);
    itemsList = new ArrayList<>();
    adapter = new ItemsAdapter(getActivity(),itemsList);
    RecyclerView.LayoutManager lm = new LinearLayoutManager(getActivity());
    rv.setAdapter(adapter);
    rv.setLayoutManager(lm);

return rootView;
}

private void populate() {
    Items a = new Items("$","this",7,8,190);
    itemsList.add(a);
    Items b = new Items("$","thi",7,8,90);
    itemsList.add(b);
    Items c = new Items("$","thi",7,8,99);
    itemsList.add(c);

    adapter.notifyDataSetChanged();

}

public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    populate();
}

Любая помощь / решение / вклад любого из вас, опытных ребят, будет высоко оценен любым полезным. Спасибо!

Замените ваш onBindViewHolder следующим образом. Это может решить вашу проблему. 

@Override
    public void onBindViewHolder(final myViewHolder holder, int position) {
        Items items = itemsList.get(position);
        holder.title.setText(items.getTitle());
        holder.currency.setText(items.getCurrency());
        holder.number.setText(String.valueOf(items.getNumber()));
        holder.budget.setText(String.valueOf(items.getBudget()));
        holder.date.setText(String.valueOf(items.getDate()));
    }

Один из setText методов Android TextView принимает целочисленный идентификатор ресурса . В методе onBindViewHolder вашего ItemsAdapter эти три строки пытаются установить текст в целое число: 

holder.number.setText(items.getNumber());
holder.budget.setText(items.getBudget());
holder.date.setText(items.getDate());

Похоже, что Android здесь не понимает ваших намерений и думает, что вы передаете ему идентификаторы ресурсов, а не целые числа, которые должны быть преобразованы в строки. Попробуйте преобразовать каждый целочисленный аргумент в строку перед передачей их в метод setText: 

holder.number.setText(String.valueOf(items.getNumber()));
holder.budget.setText(String.valueOf(items.getBudget()));
holder.date.setText(String.valueOf(items.getDate()));
