android - 在 RecyclerView 中获取微调器选择的项目

Question

我在 RecyclerView 中添加了 Spinner ，当我试图获取微调器选择的项目数据时，它得到另一个/错误的位置数据，有人建议我改正从 Spinner onItemSelected

中选择的项目和位置

这是我的代码

@Override
public void onBindViewHolder(final QuestionHolder holder, final int position) {
        if (position % 2 == 1)
            holder.itemView.setBackgroundColor(Color.parseColor("#F8F8F8"));
        adapter = new ArrayAdapter<Option>(binding.getRoot().getContext(),
                        R.layout.item_spinner, questionList.get(position).getOptions());
        adapter.setDropDownViewResource(R.layout.item_spinner);
        binding.optionSpinner.setAdapter(adapter);

        binding.serialNo.setText((position + 1) + ".");
        binding.setQuestion(questionList.get(position));
        binding.executePendingBindings();
        binding.optionSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(holder.itemView.getContext(), position+" : "+binding.optionSpinner.getSelectedItem().toString(), Toast.LENGTH_SHORT).show();
                spinnerData.setSelectedData(position, binding.optionSpinner.getSelectedItem().toString());
            }

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

            }
        });

    }

我想你必须试试这个

  showSpinnerList.setOnItemSelectedListener(new 
         AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int 
               position, long id) {
                // On selecting a spinner item

                String item = parent.getItemAtPosition(position).toString();

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {
                // todo for nothing selected
            }
        });
