谢谢 首先检查正常布局，然后检查内容是否正确连接，或者没有看到布局的xml代码 我的主要怀疑是getItemCount（）方法，您只返回一个列表的计数，我在recyclerview中看到了许多其他多个布局的实现，其中大多数使用单个列表，并将一些字段设置为null，在onBindviewholder中仅检索特定布局所需的字段，希望这有所帮助

回收服务适配器替换SimpleItemRecycleServiceAdapter
，它可以根据项目视图类型对不同类型的布局进行调整。
例如，RecycleServiceActivity
需要包含一个对象列表，如下所示：
private ArrayList<Object> getSampleArrayList() {
ArrayList<Object> items = new ArrayList<>();
items.add(new Movie ("Mad Max: Fury Road", "Action & Adventure", "2015"));
items.add(new Theatres ("Something", "something"));
items.add(new Blockbuster ("Something else", "Something else"));
return items;
}
等等
之后，您需要创建ComplexRecycleServiceAdapter
public class MoviesAdapter extends RecyclerView.Adapter<MoviesAdapter.MyViewHolder> {
private List<Movie> moviesList;
private List<Movie1> moviesList1;
final int Movie = 0, Movie1 = 1;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title, year, genre;
public MyViewHolder(View view, int viewType) {
super(view);
title = (TextView) view.findViewById(R.id.title);
genre = (TextView) view.findViewById(R.id.genre);
year = (TextView) view.findViewById(R.id.year);
}
}
public class MyViewHolder2 extends RecyclerView.ViewHolder {
public TextView title, year, genre;
public MyViewHolder2(View view, int Viewtype) {
super(view);
title = (TextView) view.findViewById(R.id.title);
genre = (TextView) view.findViewById(R.id.genre);
year = (TextView) view.findViewById(R.id.year);
}
}
@Override
public int getItemViewType(int position) {
if (moviesList.get(position) instanceof Movie) {
return Movie;
} else if (moviesList1.get(position) instanceof Movie1) {
return Movie1;
}
return -1;
}
public MoviesAdapter(List<Movie> moviesList, List<Movie1> moviesList1) {
this.moviesList = moviesList;
this.moviesList1 = moviesList1;
}
@Override

@Override

而不是SimpleItemRecycleServiceAdapter

recyclerView.setAdapter(new ComplexRecyclerViewAdapter(getSampleArrayList()));
}

谢谢朋友，什么是CodeMate中的RecycleServiceImpleTextViewHolder？它用于捕获switch语句中的意外值。。你可以忽略它，或者改变它来处理你的默认操作。你可以改变代码以便
