RecyclerView适配器从模型中获取字符串作为内存对象

标签： android android-recyclerview recycler-adapter

我有非常正常的recyclerview适配器。我将数组列表传递给适配器，并根据需要尝试使用Glide设置图像。

问题是，当我尝试将图像链接到loggin时，它们似乎正常，但是当我将数据列表传递给适配器时，它们无法正常工作。并给予内存对象而不是String。

我应该得到这个： http://somelin.com/image.jpg

相反，我得到了这个： package.name.models.responses.chain.Logo_@c170923

我该怎么办？我的适配器正常工作，因为我在其他地方以相同的方式使用此适配器并且它可以工作。

我的适配器

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

private Context mContext;
private List<Restaurant> modelList;

private OnItemClickListener mItemClickListener;

public ChainAdapter(Context context, ArrayList<Restaurant> modelList) {
    this.mContext = context;
    this.modelList = modelList;
}

public void updateList(ArrayList<Restaurant> modelList) {
    this.modelList = modelList;
    notifyDataSetChanged();
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_chain_list, viewGroup, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {

    //Here you can fill your row view
    if (holder instanceof ViewHolder) {
        final Restaurant model = getItem(position);
        ViewHolder genericViewHolder = (ViewHolder) holder;

        String link = "http://cdn.link.in/unsafe/" + model.getLogo();
        System.out.println("chainAdapter " + link);

        Glide.with(mContext).load(link).into(genericViewHolder.rest_logo);
        CenteredImageSpan imagespan = new CenteredImageSpan(mContext, R.drawable.verified_account);

        Spannable text = new SpannableString(model.getName() + "  ");
        text.setSpan(imagespan, model.getName().length(), model.getName().length() + 1, 0); //text is an object of TextView

        if (model.getVerified()) {
            genericViewHolder.rest_name.setText(text);
        } else {
            genericViewHolder.rest_name.setText(model.getName());
        }

        Calendar today = Calendar.getInstance();
        List<Today> hours = model.getToday();
        for (Today hour : hours) {
            if (hour.getWeekday() == today.get(Calendar.DAY_OF_WEEK) - 1) {
                genericViewHolder.restCloseNowIcon.setImageResource(R.drawable.ic_open_now);
                genericViewHolder.restCloseNowText.setText(mContext.getString(R.string.open_now));
                genericViewHolder.restCloseNowText.setTextColor(mContext.getResources().getColor(R.color.open_now));
            } else {
                genericViewHolder.restCloseNowIcon.setImageResource(R.drawable.ic_close_now);
                genericViewHolder.restCloseNowText.setText(mContext.getString(R.string.close_now));
                genericViewHolder.restCloseNowText.setTextColor(mContext.getResources().getColor(R.color.close_now));
            }
        }

        int totalRatings = model.getTotalRatings();

        if (totalRatings != 0)
            genericViewHolder.restStars.setText((int) totalRatings + "");
    }
}


@Override
public int getItemCount() {

    return modelList.size();
}

public void SetOnItemClickListener(final OnItemClickListener mItemClickListener) {
    this.mItemClickListener = mItemClickListener;
}

private Restaurant getItem(int position) {
    return modelList.get(position);
}


public interface OnItemClickListener {
    void onItemClick(View view, int position, Restaurant model);
}

public class ViewHolder extends RecyclerView.ViewHolder {

    @BindView(R.id.imageView8)
    ImageView rest_logo;
    @BindView(R.id.textView3)
    TextView rest_name;
    @BindView(R.id.isVerified)
    ImageView isVerified;
    @BindView(R.id.rest_close_now_icon)
    ImageView restCloseNowIcon;
    @BindView(R.id.rest_close_now_text)
    TextView restCloseNowText;
    @BindView(R.id.rest_stars)
    TextView restStars;

    public ViewHolder(final View itemView) {
        super(itemView);

        ButterKnife.bind(this, itemView);

        itemView.setOnClickListener(view -> mItemClickListener.onItemClick(itemView, getAdapterPosition(), modelList.get(getAdapterPosition())));

    }
}
}

答案 0 :(得分：1)

正如您所发现的那样，问题出现在这一行：

String link = "YOUR_URL" + model.getLogo();

您的方法getLogo（）不返回要在此处附加的字符串，而是返回类型为Logo_的对象。您有3个选择：

  1. 更改模型中的方法getLogo以返回String（可能是徽标文件名）。

  2. 在Logo对象中，创建另一个方法以返回名称并按以下方式调用它：

    String link = "YOUR_URL" + model.getLogo().getFilename();

    3. 3.在Logo对象中更改toString方法以返回文件名。

    @Override
public String toString(){
    return this.filename;
}

    编辑：您可以在徽标POJO中使用getPath（）：

    String link = "YOUR_URL" + model.getLogo().getPath();
