Question

有人有这样的样本吗？或者可以告诉适配器看起来怎么样？这是适配器内部的适配器（用于对recyclerView进行充气的适配器，以及用于对recyclerView的每个项目内的MaterialBetterSpinner布局进行充气的适配器）感谢名单！

我认为这会给你一些想法......

public class Yearly_day_type_adapter extends RecyclerView.Adapter<Yearly_day_type_adapter.MyViewHolder> {

    private List<Year_Day_Type_Model> moviesList;
    private Context context;
    TextView txt;
    int pos;
    private List<String> monthList;
    ArrayAdapter<String> monthAdapter;  

    public class MyViewHolder extends RecyclerView.ViewHolder {
        public Spinner spinner_left_yearly; 
        public MyViewHolder(View view) {
            super(view);
            spinner_left_yearly = (Spinner) view.findViewById(R.id.spinner_left_yearly);

        }
    }


    public Yearly_day_type_adapter(Context context,List<Year_Day_Type_Model> moviesList) {
        this.moviesList = moviesList;
        this.context=context;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.yearly_day_type, parent, false);



        return new MyViewHolder(itemView);
    }

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

        populateSpinner();
        holder.spinner_left_yearly.setAdapter(monthAdapter);
        holder.spinner_left_yearly.setSelection(Integer.parseInt(moviesList.get(position).getMonPos()));
        holder.spinner_left_yearly.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
                moviesList.get(position).setMonPos(String.valueOf(pos));
                MultipleSelectionActivity.setYearlyDayTypeMonth(position,pos);
            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }


        });

    }

    @Override
    public int getItemCount() {

        return moviesList.size();

    }
    public void populateSpinner() {
        monthList = new ArrayList<>();
        monthList.add("Januvary");
        monthList.add("Februvary");
        monthList.add("March");
        monthList.add("April");
        monthList.add("May");
        monthList.add("June");
        monthList.add("July");
        monthList.add("August");
        monthList.add("September");
        monthList.add("October");
        monthList.add("Novemebr");
        monthList.add("December");
        monthAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_spinner_item, monthList);
        monthAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    }

android数据绑定在RecyclerView里面的MaterialBetterSpinner
