Question

我正在使用适配器/ cardLayout / recycleView，我使用this教程进行设置

一切正常，现在我需要下载一张图片（我使用毕加索）并在卡片布局中设置，我需要在每张卡上传递：/

这就是我现在所做的事情：

 .bublina.upper {
    border-top-right-radius: 300px;
    border-top-left-radius: 300px;
    border-bottom-right-radius: 0;
    border-bottom-left-radius: 0;
 }

 .bublina.lower {
    border-top-right-radius: 0;
    border-top-left-radius: 0;
    border-bottom-right-radius: 300px;
    border-bottom-left-radius: 300px;
 }

如何将图片传递到正确的卡片？任何提示？

Answer 1

您需要在Picasso适配器方法中按onBindViewHolder加载图片。看看我在适配器中做了什么..

public class OffersAdapter extends RecyclerView.Adapter<OffersAdapter.MyViewHolder> {
    private List<OffersModel> list;
    Context mContext;


    public OffersAdapter(Context mContext, List<OffersModel> list) {
        this.list = list;
        this.mContext = mContext;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview_offers, parent, false);
        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        OffersModel offersModel = list.get(position);
        holder.product.setText(offersModel.getProduct());
        holder.description.setText(offersModel.getDiscription());
        Picasso.with(mContext)
            .load(offersModel.getImageurl())
            .into(holder.offersimage);
    }

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

    public class MyViewHolder extends RecyclerView.ViewHolder{
        ImageView offersimage;
        TextView product,description,category;
        public MyViewHolder(View itemView) {
            super(itemView);
            offersimage = (ImageView) itemView.findViewById(R.id.offersimage);
            product = (TextView) itemView.findViewById(R.id.offertitle);
            description = (TextView) itemView.findViewById(R.id.offerdescription);
        }
    }
}

删除您的ImageLoad (String Species) { . . }方法调用以及实施。像这样创建你的适配器类。

public class SimplePlants extends RecyclerView.Adapter<SimplePlants.MyViewHolder> {
private List<Plant> list;
Context mContext;


public SimplePlants(Context mContext, List<Plant> list) {
    this.list = list;
    this.mContext = mContext;
}

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.your_single_plant_layout, parent, false);
    return new MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(final MyViewHolder holder, int position) {
    Plant plant = list.get(position);
    holder.species.setText(plant.getSpecies ());
    holder.description.setText(plant.getDiscription());

    loadImage (holder.image, plant.getSpecies ());
}

public void loadImage(ImageView imageView, String specie){
    String urlFoto = "http://10.0.2.2:3000/images/" + specie + "/Thumbnail.jpg";
    Picasso.with(this)
            .load(urlFoto)
            .into(imageView);

}

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

public class MyViewHolder extends RecyclerView.ViewHolder{
    ImageView image;
    TextView species,description;
    public MyViewHolder(View itemView) {
        super(itemView);
        image = (ImageView) itemView.findViewById(R.id.image);
        species = (TextView) itemView.findViewById(R.id.title);
        description = (TextView) itemView.findViewById(R.id.description);
    }
}
}

我希望这会对你有所帮助。
