Oke, kita lanjutkan tutorial selanjutnya yaitu menambahkan list product dalam bentuk list.

Langkah - langkah nya adalah :

1. Bukan file HalamanList.java dan hapus kode yang tidak diperlukan dan hasilnya harus nya seperti code dibawah

    package id.gresikdev.foodbank.views;
    import android.os.Bundle;
    import android.support.v4.app.Fragment;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import id.gresikdev.foodbank.R;

    public class HalamanList extends Fragment {

        public HalamanList() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                Bundle savedInstanceState) {
            return inflater.inflate(R.layout.fragment_halaman_list, container, false);
        }

    }

2. buka file fragment_halaman_list.xml dan ubah codenya menjadi seperti dibawah ini

        <?xml version="1.0" encoding="utf-8"?>
        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            tools:context=".views.HalamanList">
   
            <android.support.v7.widget.RecyclerView
                android:id="@+id/list_food"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />
        </LinearLayout>
   

3. buat sebuah file pada folder layout dengan nama item_food

4. tambahkan code berikut pada file yang kamu buat

        <?xml version="1.0" encoding="utf-8"?>
            <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
   
            <ImageView
                android:id="@+id/img_food"
                android:layout_width="match_parent"
                android:layout_height="200dp"
                android:scaleType="fitXY"
                android:src="@drawable/humberger" />
   
            <TextView
                android:id="@+id/txt_food_name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="16.0dp"
                android:layout_marginTop="16.0dp"
                android:layout_marginRight="16.0dp"
                android:ellipsize="end"
                android:maxLines="1"
                android:text="Humberger"
   
                android:textColor="#000000"
                android:textSize="17.0dp" />
   
            <Button
                android:id="@+id/btn_ready_in"
                android:layout_width="150.0dp"
                android:layout_height="35.0dp"
                android:layout_gravity="right"
                android:layout_margin="16.0dp"
                android:background="@drawable/background_tombol"
                android:text="Ready in 26 min"
                android:textAllCaps="false"
                android:textColor="#FFFFFF" />
            </LinearLayout>

6. Tambahkan file java pada folder model dengan nama Food.

7. Tambahkan kode berikut

        package id.gresikdev.foodbank.models;
        import android.graphics.drawable.Drawable;
   
        public class Food {
            String foodName;
            Drawable foodImage;
            String foodDetail;
            String foodBtnTitle;
            int foodPrice;
   
            public Food(String foodName, Drawable foodImage, String foodDetail, String foodBtnTitle, int foodPrice) {
                this.foodName = foodName;
                this.foodImage = foodImage;
                this.foodDetail = foodDetail;
                this.foodBtnTitle = foodBtnTitle;
                this.foodPrice = foodPrice;
            }
   
            public Food() {
            }
   
            public String getFoodName() {
                return foodName;
            }
   
            public void setFoodName(String foodName) {
                this.foodName = foodName;
            }
   
            public Drawable getFoodImage() {
                return foodImage;
            }
   
            public void setFoodImage(Drawable foodImage) {
                this.foodImage = foodImage;
            }
   
            public String getFoodDetail() {
                return foodDetail;
            }
   
            public void setFoodDetail(String foodDetail) {
                this.foodDetail = foodDetail;
            }
   
            public String getFoodBtnTitle() {
                return foodBtnTitle;
            }
   
            public void setFoodBtnTitle(String foodBtnTitle) {
                this.foodBtnTitle = foodBtnTitle;
            }
   
            public int getFoodPrice() {
                return foodPrice;
            }
   
            public void setFoodPrice(int foodPrice) {
                this.foodPrice = foodPrice;
            }
        }
   

8. Tambahkan file java pada folder adapter dengan nama ListFoodController

9. Edit dan tambahkan code dibawah ini

         package id.gresikdev.foodbank.adapter;

         import android.content.Context;
         import android.support.annotation.NonNull;
         import android.support.v7.widget.RecyclerView;
         import android.view.LayoutInflater;
         import android.view.View;
         import android.view.ViewGroup;
         import android.widget.Button;
         import android.widget.ImageView;
         import android.widget.TextView;

         import java.util.ArrayList;

         import id.gresikdev.foodbank.R;
         import id.gresikdev.foodbank.models.Food;

         public class ListFoodController extends RecyclerView.Adapter<ListFoodController.ListFoodHolder> {


             private ArrayList<Food> listFood;
             private Context context;

             public ListFoodController(ArrayList<Food> listFood, Context context) {
                 this.listFood = listFood;
                 this.context = context;
             }

             @NonNull
             @Override
             public ListFoodHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
                 return new ListFoodHolder(LayoutInflater.from(context).inflate(R.layout.item_food, viewGroup, false));
             }

             @Override
             public void onBindViewHolder(@NonNull ListFoodHolder listFoodHolder, int i) {
                 Food myFood = listFood.get(i);
                 listFoodHolder.bind(myFood);
             }

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

             class ListFoodHolder extends RecyclerView.ViewHolder {
                 ImageView foodImage;
                 TextView title;
                 Button foodInfo;

                 private ListFoodHolder(@NonNull View itemView) {
                     super(itemView);
                     foodImage = itemView.findViewById(R.id.img_food);
                     title = itemView.findViewById(R.id.txt_food_name);
                     foodInfo = itemView.findViewById(R.id.btn_ready_in);
                 }

                 void bind(Food food) {
                     foodImage.setImageDrawable(food.getFoodImage());
                     title.setText(food.getFoodName());
                     foodInfo.setText(food.getFoodBtnTitle());
                 }
             }
         }

10. Buka file HalamanList.java kemudian edit menjadi seperti dibawah ini

            public class HalamanList extends Fragment {
            private ArrayList<Food> myFoods = new ArrayList<>();
            private RecyclerView mylistFood;
            private ListFoodController listAdapter;
    
            public HalamanList() {
            }
    
            private View myView;
    
            private void getFood() {
                for (int i = 0; i < 100; i++) {
                    myFoods.add(new Food("Food number " + i, getResources().getDrawable(R.drawable.donut), "detail food", "Ready in " + (10 * i) + " min", i));
                }
            }
    
            private void setView() {
                getFood();
                mylistFood = myView.findViewById(R.id.list_food);
                listAdapter = new ListFoodController(myFoods, getContext());
                mylistFood.setLayoutManager(new LinearLayoutManager(getContext()));
                mylistFood.setAdapter(listAdapter);
            }
    
            @Override
            public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                    Bundle savedInstanceState) {
                myView = inflater.inflate(R.layout.fragment_halaman_list, container, false);
                setView();
                return myView;
            }
    
        }
