Answer 1

You can use Glide to load image into your ImageView e.g.

Glide.with(context).load(imagePath).into(imageView);

imagePath could be Remote URL, Drawable asset, Bitmap, File Uri etc.

In your case you are loading picture name received in json response you need to attach BASE URL with picture variable to make complete path to the image

RecyclerViewAdapter.java

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
Context context;
ArrayList<DataList> arrName;

public RecyclerViewAdapter(Context context, ArrayList<DataList> arrName) {
    this.context = context;
    this.arrName = arrName;
}


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

@Override
public void onBindViewHolder(@NonNull ViewHolder viewHolder, int i) {
    viewHolder.name.setText(arrName.get(i).getName());
    viewHolder.address.setText(arrName.get(i).getAddress());
    DataList datalist = arrName.get(i);

    byte[] recordImage = datalist.getImage();
    Bitmap bitmap = BitmapFactory.decodeByteArray(recordImage, 0, recordImage.length);
    viewHolder.img.setImageBitmap(bitmap);
}

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

public class ViewHolder extends RecyclerView.ViewHolder {
    TextView name, address;
    ImageView img;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);
        name = itemView.findViewById(R.id.name);
        address = itemView.findViewById(R.id.addr);
        img = itemView.findViewById(R.id.image);
    }

        arrnames.add(new DataList(name, address, img));
        adapter.notifyDataSetChanged();
