Question

Recycleview用于项目。卡视图使用Imageview，ImageButton，TextView。当用户单击ImageView在objectbox数据库中存储的图像链接时。两个图像按钮显示为喜欢和不同。当用户单击喜欢或不喜欢的图像按钮时，将类似和不喜欢的图像按钮存储在数据库中。

如何通过不同的点击侦听器在数据库中存储图像以及喜欢和不喜欢的东西。

public class ThumbnailAdapter extends RecyclerView.Adapter<ThumbnailAdapter.MyViewHolder>{

    private Context mContext;
    private List<Thumbnail> albumList;
    private List<Giphy> giphyList;

    private BoxStore boxStore;
    private Box<Giphy> box;

    public class MyViewHolder extends RecyclerView.ViewHolder {
       // public TextView title, count;

        @BindView(R.id.imgThumbnail)
        public ImageView imageView;

        @BindView(R.id.imgButtonThumbUp)
        public ImageButton imageButtonUP;

        @BindView(R.id.imgButtonThumbDown)
        public ImageButton imageButtonDown;

        @BindView(R.id.tvThumbUpCount)
        public TextView tvUpCount;

        @BindView(R.id.tvThumbDownCount)
        public TextView tvCountDown;

        int countUP = 0;
        int countDown = 0;

        String url;
        int id = 0;
        int thumbUp,thumbDown;

        public MyViewHolder(View view) {
            super(view);
            mContext = view.getContext();
            //imageView = (ImageView) view.findViewById(R.id.imgThumbnail);

            ButterKnife.bind(this,view);




            int idCount = id++;

            giphyList = new ArrayList<>();


            imageView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                   // String Title = title.getText().toString();

                    Thumbnail list = albumList.get(getAdapterPosition());

                    url = list.getVideoUrl();
                    giphyList.add(new Giphy(0,url,thumbUp,thumbDown));

            addData(new Giphy(0,url,thumbUp,thumbDown));


        }



    }

    }

        Glide.with(mContext)

    }

    @Override

        return albumList.size();

   public void addData(Giphy giphy){

    }

Answer 1

在onBindViewHolder中，将该位置设置为ImageButton的标签：

holder.imageButtonUp.setTag(position);
holder.imageButtonDown.setTag(position);

然后在ImageButton的onClickListener中，获取位置：

int position = (Integer)view.getTag();
Thumbnail album = albumList.get(position);

然后做任何你想做的事。

但是当您使用Glide时，Glide使用ImageView的标签，因此您应该通知Glide使用另一个标签。看到这个：

Error "You must not call setTag() on a view Glide is targeting" when use Glide
