嗨，我正在根据用户选择动态创建微调器列表。在这里，我还为每个微调器实现 OnItemSelectedListener，因为有多个微调器我想知道当前正在访问哪个微调器的方法。这是代码，

     for (int i = 0; i < count; i++) {
        ArrayList<String> spinnerArray = new ArrayList<String>();
        spinnerArray.add("one");
        spinnerArray.add("two");
        spinnerArray.add("three");
        spinnerArray.add("four");
        spinnerArray.add("five");

        Spinner spinner = new Spinner(this);

        spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {

                Object item = parent.getItemAtPosition(position);
                Log.d("vij-debug", "selector1 no is " + item);
                Log.d("vij-debug", "selector1 id is"+ view.getId());

                 //medicineArray1[i][1]=(String)item;
                // here I want to access the iteration value i



            }

            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

        ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(
                this, android.R.layout.simple_spinner_dropdown_item,
                spinnerArray);
        spinner.setAdapter(spinnerArrayAdapter);

任何人都可以提出一个合适的解决方案吗？

在创建时将Spinner's 标记设置为，然后从 中的参数中i检索它。AdapterView<?> parentonItemSelected()

Spinner spinner = new Spinner(this);
spinner.setTag(i);
...
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
    {
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
        {
            int spinnerNumber = parent.getTag();
        }
        ...
    }
);

您可以使用 aList并将您的微调器存储在那里。在你的 for 循环中

//inside for loop
List<Spinner> spinnerList=new ArrayList<Spinner>();
Spinner spinner = new Spinner(this);
spinnerlist.add(spinner);

//end

//outside for loop
for(int i=0;i<spinnerList.size();i++){

setListenerToSpinner(spinnerList.get(i));

}

//end


//function
public void setListenerToSpinner(Spinner spinner){

spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view,
                    int position, long id) {

                Object item = parent.getItemAtPosition(position);
                Log.d("vij-debug", "selector1 no is " + item);
                Log.d("vij-debug", "selector1 id is"+ view.getId());

                 //medicineArray1[i][1]=(String)item;
                // here I want to access the iteration value i

            }

}
