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);
        }

    }
  1. 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>
    
  2. buat sebuah file pada folder layout dengan nama item_food

  3. 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>
    
  4. Download dan tambahkan gambar disini Noted : Gambar mungkin memiliki hak cipta, saya sarankan gunakan gambar lain yang sudah jelas tidak memiliki hak cipta agar aplikasi tidak ditolak di playstore.

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

  6. 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;
             }
         }
    
  7. Tambahkan file java pada folder adapter dengan nama ListFoodController

  8. 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());
                 }
             }
         }

  1. 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;
            }
    
        }
