从RecyclerView内的RadioGroup获取上一个RadioButton值

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> data;
    private int lastCheckedPosition = -1;

    public MyAdapter(List<String> data) {
        this.data = data;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.radioButton.setText(data.get(position));
        holder.radioButton.setChecked(position == lastCheckedPosition);
    }

    @Override
    public int getItemCount() {
        return data.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        RadioButton radioButton;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            radioButton = itemView.findViewById(R.id.radioButton);

            radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if (isChecked) {
                        lastCheckedPosition = getAdapterPosition();
                        // 获取上一个RadioButton的值
                        if (lastCheckedPosition > 0) {
                            String previousValue = data.get(lastCheckedPosition - 1);
                            // 进行相应的处理
                        }
                    }
                }
            });
        }
    }
