Question

我可以在模拟器中看到来自Firebase的图像，但是当我发布到手机上时却看不到手机中的图像。我正在使用 Firebase 实时数据库和Picasso库。我将图片网址存储在数据库中。我使用毕加索显示图片。但是我可以在模拟器中看到图像，看不到手机。我尝试使用“ with”功能，但是代码不允许使用。我怎样才能解决这个问题？

public class IngredientsAdapter extends 
RecyclerView.Adapter <IngredientsAdapter.MyViewHolder> {
**Context** mContext;
ArrayList<Ingredients> mIngredientsArrayList;
CustomItemClickListener mListener;
public IngredientsAdapter(Context context, ArrayList<Ingredients> 
ingredientsArrayList, CustomItemClickListener listener) {
    mContext = context;
    mIngredientsArrayList = ingredientsArrayList;
    mListener = listener;
}



   @Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    final View view = 
    LayoutInflater.from(mContext).inflate(R.layout.soup_cardview, parent, false);
    final MyViewHolder viewHolder = new MyViewHolder(view);
    view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mListener.onItemClick(view, viewHolder.getAdapterPosition());
        }
    });
    return viewHolder;
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {


    holder.soupName.setText(mIngredientsArrayList.get(position).getName());
   Picasso.get().load(mIngredientsArrayList.get(position).getImage()).into(holder.soupImage);
}

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

class MyViewHolder extends RecyclerView.ViewHolder {
    TextView soupName;
    ImageView soupImage;
    TextView soupIngredients;
    TextView soupDetail;


    public MyViewHolder(View itemView) {
        super(itemView);
        soupName = itemView.findViewById(R.id.menu_name);
        soupImage=itemView.findViewById(R.id.menu_image);

    }  }

Answer 1

打开硬件加速后，设备可以渲染最大图像大小。此大小取决于设备。如果位图大于此大小-将不会呈现。

int[] maxSize = new int[1];
GLES20.glGetIntegerv(GLES20.GL_MAX_TEXTURE_SIZE, maxSize, 0);

模拟器正在显示我的图像。但是我的手机不能
