Question

imageList应该是arraylist

以及在我的bean中如何将其转换为Drawable和我们如何将其设置为bean中的参数

在给定的类下面是我的豆子

public class ParkPhotoFetchBean {
    private int parkPics;
    arraylist should come here

，我们需要将其更改为可绘制的如何通过将其更改为drawableimage来设置

    void ParkPhotoFetchBin(int parkPics){
        this.parkPics = parkPics;
    }

    public int getParkPics() {
        return parkPics;
    }
getter and setter
    public void setParkPics(int parkPics) {
        this.parkPics = parkPics;
    }

}

另一堂课是

import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.DividerItemDecoration;
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

解决方案：

代替此：

ParkPhotoFetchBean parkPhotoFetchBean = new ParkPhotoFetchBean(imagesList);

写：

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

现在，您可以在包含来自Bean类的图像的活动中使用parkingPhotoList。您不必将arraylist传递给bean类。您的图片将显示在RecyclerView

中

Arraylist整数到android中的可绘制图像
