Question

我正在使用一个库悬停在recylerview的项目上，但是项目的列表器工作之前没有工作，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;
        }

    }
}

如果没有看到你的xml并根据我的理解，我会建议试试这个 -

onCreateViewHolder（）替换为此

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

在itemView.setOnClickListener（）之前将它放在 -

之前

itemView.setClickable(true);

我不确定正确的方法来膨胀xml但是我正在使用下面的代码来扩展xml我需要的地方除了recyclerView适配器onCreateViewHolder（）方法回调 -

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

如果这样可以解决您的问题，请将此帖标记为答案希望这有帮助
