android - 如何在 recyclerview 的项目上膨胀 xml 文件？

Question

我正在使用一个库将鼠标悬停在 recylerview 的项目上，但是项目的监听器不工作，它以前工作过，而且问题是——在另一个膨胀的 xml 文件上膨胀新的 xml 文件的正确方法是什么？

提前致谢。

public class LessonVideoAdapter extends RecyclerView.Adapter<LessonVideoAdapter.LessonDataHolder> {

    private List<VideoList> slipList;


    public LessonVideoAdapter() {
        slipList = new ArrayList<>();
        slipList.add(new VideoList("Chapter 1", R.drawable.demo_one));
        slipList.add(new VideoList("Chapter 2", R.drawable.demo_two));
        slipList.add(new VideoList("Chapter 3", R.drawable.demo_one));
        slipList.add(new VideoList("Chapter 4", R.drawable.demo_two));


    }

    @Override
    public LessonDataHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        Context context = parent.getContext();
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.abc_card_view_video, parent, false);

        return new LessonDataHolder(view);

    }

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

        VideoList s = slipList.get(position);
        holder.bindSlip(s);

    }

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


    public class LessonDataHolder extends RecyclerView.ViewHolder {

        public BlurLayout samplelayout;
        private TextView nameOfSlip;
        private ImageView slipImage;
        private Context context;


        public LessonDataHolder(View itemView) {
            super(itemView);

            context = itemView.getContext();
            nameOfSlip = (TextView) itemView.findViewById(R.id.demoText);
            slipImage = (ImageView) itemView.findViewById(R.id.imageViewDemoVideo);

            itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    {
                        Log.d("ashu", " clicked " + getAdapterPosition());

                    }
                }
            });
        }

        public void bindSlip(VideoList videoList) {
            nameOfSlip.setText(videoList.stringSlipName);
            slipImage.setImageResource(videoList.stringImage);
        }
    }


    public class VideoList {
        public String stringSlipName;
        public int stringImage;

        public VideoList(String stringSlipName, int stringImage) {
            this.stringImage = stringImage;
            this.stringSlipName = stringSlipName;
        }

    }
}

在没有看到你的 xml 的情况下，根据我的理解，我建议试试这个 -

onCreateViewHolder() 替换为这个

View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.abc_card_view_video, parent, false);
return new LessonDataHolder(v);  

在 itemView.setOnClickListener() 之前放这个 -

itemView.setClickable(true); 

我不确定膨胀 xml 的正确方法，但我使用下面的代码在我需要的地方膨胀 xml，除了 recyclerView 适配器 onCreateViewHolder() 方法回调 -

View view = getLayoutInflater(null).inflate(R.layout.scanner_manual_entry, null);
