无法在相册的“回收者”视图中显示多个图像

Question

我正在创建一个活动，用户可以从手机照片库中选择图像，然后这些照片将使用毕加索显示在“回收者视图”中并存储在Firebase存储器中。我已经尝试了所有解决方案，但是图像未在Recycler View中加载。

我的AddProduct.java代码

imgAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent();
                intent.setType("image/*");
                intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);//Specify the type of intent
                intent.setAction(Intent.ACTION_GET_CONTENT);             //What action needs to be performed.
                startActivityForResult(Intent.createChooser(intent, "Select Product Image"), PICK_IMAGE);
            }
        });

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if(requestCode == PICK_IMAGE && resultCode == RESULT_OK){
            if(data.getClipData()!= 
                int totalItemsSelected = data.getClipData().getItemCount();
                for(int j = 0; j < totalItemsSelected; j++){
                    Uri fileUri = data.getClipData().getItemAt(j).getUri();
                    mImageUrls.add(fileUri);
                }
            }else if(data.getData()!=null){
                Toast.makeText(getApplicationContext(), "Single file selected.", Toast.LENGTH_SHORT).show();
            }
        }

        LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
        RecyclerView recyclerView = findViewById(R.id.rvPhotos);
        recyclerView.setLayoutManager(layoutManager);
        AddProductPicAdapter adapter = new AddProductPicAdapter(this, mImageUrls);
        recyclerView.setAdapter(adapter);
    }

我的适配器代码

import android.content.Context;
import android.net.Uri;
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.ImageView;
import com.bumptech.glide.Glide;
import com.squareup.picasso.Picasso;
import java.util.ArrayList;

public class AddProductPicAdapter extends RecyclerView.Adapter<AddProductPicAdapter.ViewHolder> {

    private ArrayList<Uri> mImageUrls;
    private Context mContext;

    public AddProductPicAdapter(Context context, ArrayList<Uri> imageUrls) {
        this.mImageUrls = imageUrls;
        this.mContext = context;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {     //This binds the layout file.
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.add_product_pic_layout, viewGroup, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder viewHolder, int i) {           //This binds the data.
        Picasso.get().load(mImageUrls.get(i)).fit().centerCrop().into(viewHolder.image);


    }

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

    public class ViewHolder extends RecyclerView.ViewHolder{

        ImageView image;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);

            image = itemView.findViewById(R.id.ivProdImage);
        }
    }
}
