Question

在我的应用程序中，我在listview中有一个微调器，下面的代码是我管理微调器的。

在listview适配器的getview（）内部

    addSpinnerValue(mList.get(position).getSchedule());// method to set the ArrayAdapter to spinner
    spinnerSchedule.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                Log.w("onCLick","position"+arg2);

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        }); 

  //Method which is setting the spinner Adapter(Outside the getview)
  public void addSpinnerValue(String schedule) {
    ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(Activity_ManageListing.this,R.layout.row_spinner, R.id.textView1, spinnerforlist);
    spinnerSchedule.setAdapter(adapter1); 
  }

当微调器点击时，我收到错误：

整天我试图解决这个问题，但仍然存在。任何人都可以指导解决此问题

先谢谢

编辑：我的疑问是为什么我得到这个以下错误，而spinner onclick

错误Spinner setOnItemSelectedListener：android.view.WindowManager $ BadTokenException：无法添加窗口 - 令牌null不适用于应用程序
