another class is

import androidx.appcompat.app.AppCompatActivity;

import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

import android.app.Activity;
import android.graphics.drawable.Drawable;
import android.os.Bundle;

import com.project.parkingapplication.adapter.HorizontalRecyclerAdapter;
import com.project.parkingapplication.entities.ParkPhotoFetchBean;

import java.util.ArrayList;
import java.util.List;

public class BookingDetail extends AppCompatActivity {
    private List<ParkPhotoFetchBean> parkingPhotoList = new ArrayList<>();
    RecyclerView rvContainer;
    Activity activity;
    HorizontalRecyclerAdapter myRecyclerViewAdapter;
    com.project.parkingapplication.entities.ParkPhotoFetchBean myRecyclerBean;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_booking_detail);
        activity = this;
        rvContainer.addItemDecoration(new DividerItemDecoration(BookingDetail.this, LinearLayoutManager.HORIZONTAL));
        myRecyclerViewAdapter = new HorizontalRecyclerAdapter(parkingPhotoList, this);
        LinearLayoutManager horizontalLayoutManager = new LinearLayoutManager(BookingDetail.this, LinearLayoutManager.HORIZONTAL, false);
        rvContainer.setLayoutManager(horizontalLayoutManager);
        rvContainer.setAdapter(myRecyclerViewAdapter);
        populatePhotoList();

    }

    private void populatePhotoList() {
        ArrayList<Integer> imagesList = new ArrayList();
        imagesList.add(R.drawable.image1);
        imagesList.add(R.drawable.image2);
        imagesList.add(R.drawable.image3);
        imagesList.add(R.drawable.image4);
        imagesList.add(R.drawable.car);

        ParkPhotoFetchBean parkPhotoFetchBean = new ParkPhotoFetchBean(imagesList); //image List should be array list and in my //bean how i can convert it into drawable

    }

    private void mappingWidget() {
        rvContainer = findViewById(R.id.rv_booking_detail_image_slider);
    }
}

Answer 1

Solution:

Instead of this:

ParkPhotoFetchBean parkPhotoFetchBean = new ParkPhotoFetchBean(imagesList); 

Write:

for(int i=0; i<imagesList.size(); i++) 
{
    parkingPhotoList.add(new ParkPhotoFetchBean(imagesList.get(i)))
}
myRecyclerViewAdapter.notifyDataSetChanged()

Now, you can use parkingPhotoList in your activity which contains your images from the bean class. You don't have to pass your arraylist to your bean class. You images will be displayed in RecyclerView
