Question

我正在使用Recycleview在Horizontal RecyclerView中显示联系人图像和姓名，并且可以正常加载。我已经实现了Click侦听器，该侦听器在单击时会打开新活动并根据RecyclerView的位置向用户显示详细信息。

但是我希望对RecyclerView进行自动滚动，以便每5秒钟recycleview自动滚动一次，我实现了以下代码，效果很好。

 top.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                int lastItem = llm.findLastCompletelyVisibleItemPosition();
                if(lastItem == llm.getItemCount()-1){
                    mHandler.removeCallbacks(SCROLLING_RUNNABLE);
                    Handler postHandler = new Handler();
                    postHandler.postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            top.setAdapter(null);
                            top.setAdapter(staggeredBooksAdapter);
                            mHandler.postDelayed(SCROLLING_RUNNABLE, 5000);
                        }
                    }, 5000);
                }
            }
        });
        mHandler.postDelayed(SCROLLING_RUNNABLE, 5000);

但是现在，当我单击任何联系人时，将不会像以前那样启动带有用户详细信息的新活动。但是，当我删除滚动侦听器时，我可以再次单击RecyclerView项。

我的RecyclerView是

      final LinearLayoutManager llm = new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false);
        top.setLayoutManager(llm);
        top.setHasFixedSize(true);
        staggeredBooksAdapter = new TopAdapter(this, bookslist);

        top.setAdapter(staggeredBooksAdapter);

并且来自适配器类是

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

        database = FirebaseDatabase.getInstance();

        g = bookslist.get(position);

        holder.teacher_location.setText(g.getBlocas());
        holder.teacher_name.setText(g.getSellername());

        holder.profile_details.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                g = bookslist.get(position);
                Intent intent = new Intent(v.getContext(), gender_details.class);
                intent.putExtra(KEY_IMAGE, g.getPics());



                v.getContext().startActivity(intent);
            }
        });

我该如何解决。。谢谢。

将this类添加到您的项目中，然后添加以下代码：

recyclerView.addOnItemTouchListener(new RecyclerItemClickListener(
        this, top, new RecyclerItemClickListener.OnItemClickListener() {
    @Override
    public void onItemClick(View view, int position) {
        Log.i("recyclerView ", "onItemClick " + position);
    }

    @Override
    public void onLongItemClick(View view, int position) {
        Log.i("recyclerView ", "onLongItemClick " + position);
    }
}));

让我知道它是否有效。
