Question

我的Recycler View中的所有内容都工作得很好，除了这个问题，当片段启动时，第一个在Recycler View中显示的列表有设计问题，滚动后它是正确的并修复它！什么是原因？这是我的Recycler视图适配器：

        View rootView = inflater.inflate(R.layout.fragment_order_list, container,
            false);

    recyclerView = (RecyclerView) rootView.findViewById(R.id.my_recycler_view);

    mAdapter = new MoviesAdapter(movieList);
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getContext());
    recyclerView.setLayoutManager(mLayoutManager);
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(mAdapter);

    prepareMovieData();

这就是我回收的XML行：

这是结果！为什么会这样？正如您在第一个列表结果中显示的那样，我们在设计中遇到问题，并在滚动后通过回收站查看修复！

我曾经遇到过这样的问题，通过在recyclerView适配器中添加这些方法解决了这个问题。这样做的是它甚至在可见之前重新加载行。

    @Override
    public void onViewAttachedToWindow(ViewHolder holder) {
        super.onViewAttachedToWindow(holder);
        int wPosition = holder.getAdapterPosition();   // if you need the position of current item else ignore..
        /* copy paste whatever you have in your onBindViewHolder method here */
     }

    @Override
    public void onViewRecycled(ViewHolder holder) {
         super.onViewRecycled(holder);
    /* copy paste whatever you have in your onBindViewHolder method here */

     }

第一个结果中的Recycler视图与滚动设计不同？
